• Eclipse wont open Android Xml files

  - by mike

  I'm just starting with Android and everything seems to be working fine, but when I try to look at any XML file in eclipse, I get the following error. The only way I can see them is by "Opening With" - TextFile. org.eclipse.core.runtime.CoreException: Error opening the Android XML editor. Is the document an XML file? at com.android.ide.eclipse.adt.internal.editors.AndroidEditor.createTextEditor(Unknown Source) at com.android.ide.eclipse.adt.internal.editors.AndroidEditor.createAndroidPages(Unknown Source) at com.android.ide.eclipse.adt.internal.editors.AndroidEditor.addPages(Unknown Source) at org.eclipse.ui.forms.editor.FormEditor.createPages(FormEditor.java:138) at org.eclipse.ui.part.MultiPageEditorPart.createPartControl(MultiPageEditorPart.java:357) at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:662) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:462) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.EditorReference.getEditor(EditorReference.java:286) at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditorBatched(WorkbenchPage.java:2857) at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditor(WorkbenchPage.java:2762) at org.eclipse.ui.internal.WorkbenchPage.access$11(WorkbenchPage.java:2754) at org.eclipse.ui.internal.WorkbenchPage$10.run(WorkbenchPage.java:2705) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:70) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2701) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2685) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2676) at org.eclipse.ui.ide.IDE.openEditor(IDE.java:651) at org.eclipse.ui.ide.IDE.openEditor(IDE.java:610) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.openInEditor(EditorUtility.java:361) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.openInEditor(EditorUtility.java:168) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:229) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:208) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.dispatchRun(SelectionDispatchAction.java:274) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.run(SelectionDispatchAction.java:250) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerActionGroup.handleOpen(PackageExplorerActionGroup.java:373) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart$4.open(PackageExplorerPart.java:526) at org.eclipse.ui.OpenAndLinkWithEditorHelper$InternalListener.open(OpenAndLinkWithEditorHelper.java:48) at org.eclipse.jface.viewers.StructuredViewer$2.run(StructuredViewer.java:842) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.runtime.Platform.run(Platform.java:888) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:48) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:175) at org.eclipse.jface.viewers.StructuredViewer.fireOpen(StructuredViewer.java:840) at org.eclipse.jface.viewers.StructuredViewer.handleOpen(StructuredViewer.java:1101) at org.eclipse.jface.viewers.StructuredViewer$6.handleOpen(StructuredViewer.java:1205) at org.eclipse.jface.util.OpenStrategy.fireOpenEvent(OpenStrategy.java:264) at org.eclipse.jface.util.OpenStrategy.access$2(OpenStrategy.java:258) at org.eclipse.jface.util.OpenStrategy$1.handleEvent(OpenStrategy.java:298) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3880) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3473) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2405) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2369) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:194) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:368) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

• WstxParsingException: "Expected a text token, got START_ELEMENT"

  - by lasombra

  I have a stub generated by WSDL2Java. I send a request and the answer that comes back (used tcptrace) looks fine. However, an AxisFault is thrown: org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxParsingException: Expected a text token, got START_ELEMENT. at [row,col {unknown-source}]: [4,1313] at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430) at org.tempuri.MyStub.fromOM(MyStub.java:1726) at org.tempuri.MyStub.acceptResults(MyStub.java:612) The corresponding code in MyStub.java looks like: 607: org.apache.axis2.context.MessageContext _returnMessageContext = _operationClient 608: .getMessageContext(org.apache.axis2.wsdl.WSDLConstants.MESSAGE_LABEL_IN_VALUE); 609: org.apache.axiom.soap.SOAPEnvelope _returnEnv = _returnMessageContext 610: .getEnvelope(); 611: 612: java.lang.Object object = fromOM(_returnEnv.getBody() 613: .getFirstElement(), 614: org.tempuri.AcceptQcResultsResponse.class, 615: getEnvelopeNamespaces(_returnEnv)); How do I find out which token is meant by the error? I have [row,col {unknown-source}]: [4,1313] but I don't know how to use that information.

• How to get a safecontrol entry into manifest.xml with WSPBuilder project

  - by andrew

  Upon taking the default sharepoint master page for MySite, making some changes, and making a wsp out of it with WSPBuilder, I come to these errors in my logs: http://spoint/MySite/%5Fcatalogs/masterpage/MySite.master - An unexpected error has been encountered in this Web Part. Error: The control with virtual path '_controltemplates/Welcome.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite'., Source: [UnsafeControlException: The control with virtual path '_controltemplates/Welcome.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite' (stack trace omitted) http://spoint/MySite/%5Fcatalogs/masterpage/MySite.master - An unexpected error has been encountered in this Web Part. Error: The control with virtual path '_controltemplates/DesignModeConsole.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite'., Source: [UnsafeControlException: The control with virtual path '_controltemplates/DesignModeConsole.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite' (stack trace ommited) So, this masterpage does in fact use these OOTB controls and so I guess I need to get them safecontrolled. And I guess I want to do this via the manifest.xml. But I do not see how to make WSPBuilder do this.

• Setting collation property in the connection string to SQL Server 2005

  - by user369745

  I have a ASP.Net web application with connection string for SQL Server 2005 in the web.config. Data Source=ABCSERVER;Network Library=DBMSSOCN;Initial Catalog=myDataBase; User ID=myUsername;Password=myPassword; I want to specify the collation property in the web.config for different languages like French like Data Source=ABCSERVER;Network Library=DBMSSOCN;Initial Catalog=myDataBase; User ID=myUsername;Password=myPassword;Collation=French_CS_AS But the Collation word is not valid in the connection string. What is the correct keyword that we need to use to specify the collation in SQL Server 2005 connection string?

• Embed SQL Password into Crystal Reports RPT file?

  - by codeulike

  We are experimenting with Crystal Reports viewers such as this one: http://www.thereportviewer.com/ ... which can actually re-connect to the data source and re-run a Crystal Reports RPT file with live data. However when running the report the viewer asks for a password to connect to the data source (in this case SQL Server). Does Crystal Reports have some way of embedding a connection password into a RPT file to avoid this? Or should I be using a System DSN from the Control Panel/ODBC thing to get around this? I figure someone else must have had this problem.

• ProcessAjaxOpenIdResponse doesn't exist in OpenAuth library?

  - by Stacey

  Using the NerdDinner 2.0 source code, I was trying to emulate its use of OpenID. All was fine and good until I ran into this line of code.. ( seen in the source code at : http://nerddinner.codeplex.com/sourcecontrol/network/Show?projectName=nerddinner&changeSetId=46375#952606 ) - ( trunk/nerddinner/services/OpenIdRelyingPartyService.cs ) public ActionResult ProcessAjaxOpenIdResponse() { return relyingParty.ProcessAjaxOpenIdResponse().AsActionResult(); } ProcessAjaxOpenIdResponse doesn't exist, though! If I download the nerddinner application and follow the dependancies, I can see that the OpenAuth library they use has this method. However, getting the newest version from http://www.dotnetopenauth.net/ - the library does not have this method. Any ideas on what happened to it, and what I should use instead?

• HTML5 video tag in chrome - wmv

  - by elcuco

  Hi Al, I need to make a page which displays a video. Firefox and and Opera support the OGG format, no problem there. Chrome is ... "stupid" and does not recognize OGG. Does Chrome on Windows know how to handle WMV? I already have them encoded, and no I cannot recode new videos since the media is limited in spaced (CDROM). My code currently looks like this (and not working in chrome) <video controls> <source codecs="theora, vorbis" media="video/ogg" src="video.ogv" /> <source media="video/x-ms-wmv" src="video.wmv" /> Please install a new browser, or just get out </video> Note that I am missing a codec entry, does anyone know what I need to put there?

• fullCalendar className to multiple eventSources

  - by Justin

  I am trying to setup my fullCalendar event sources. instead of pulling all of my events through 1 source, I would like to use multiple sources (ie: google, and local json) Here is what I have so far (In short): eventSources: [ //CA HOLIDAYS $.fullCalendar.gcalFeed('http://www.google.com/calendar/feeds/en.canadian%23holiday%40group.v.calendar.google.com/public/basic', { className: 'holiday' }), //General events 'events.php?a=getAllCalendarEvents' ], The problem that I am having is, I can get the gCalFeed to have a className, but not exactly sure how to get my other source to have a className... Any ideas would be greatly appreciated.

• SCCM 2012 unable to update boot images with pxe enabled

  - by Adam

  we are fighting an error in sccm 2012. When we attempt to distribute boot images (after selecting the pxe option) we receive an error that the pxe image cannot be expanded (distmgr log). Can you give us any direction on what to try or attempt in this scenario? We only have one dp in our environment at the moment, however we have found that by creating another dp on a different server we don’t have this problem. However we really need the primary site to be a dp. We have tried: Removing and reinstalling the dp Removing and reinstalling the WDS Reinstalled the OS ... ouch Reinstalled SQL We even attempted to manually mount these wims in the remote install folder, no luck... And we have been working on this for days... Any and all help is appreciated! Our log is below Thank you very much, Small Town IT guy Attempting to add or update a package on a distribution point.

• Exception seem in an eclipse GMF application when file not present in workspace

  - by rush00121

  I am developing a GMF application . In this situation , I start my workspace and load a file in the workspace . Then I close the workspace and then delete the file from the workspace . After that, I try to restart my application and restore the workspace . Of course , now since the file does not exist , there are going to be exceptions . I tried a lot to handle these exceptions but if I try to get rid of one exception , then another pops up . Does anyone know what methods do I have to override in order to handle this situation correctly .

• java 7 upgrade and hibernate annotation processor error

  - by Bill Turner

  I am getting the following warning, which seems to be triggering a subsequent warning and an error. I have been googling like mad, though have not found anything that makes it clear what it is I should do to resolve this. This issue occurs when I execute an Ant build. I am trying to migrate our project to Java 7. I have changed all the source='1.6' and target="1.6" to 1.7. I did find this related article: Forward compatible Java 6 annotation processor and SupportedSourceVersion It seems to indicate that I should build the Hibernate annotation processor jar myself, compiling it with with 1.7. It does not seem I should be required to do so. The latest version of the class in question (in hibernate-validator-annotation-processor-5.0.1.Final.jar) has been compiled with 1.6. Since the code in said class refers to SourceVersion.latestSupported(), and the 1.6 of that returns only RELEASE_6, there does not seem to be a generally available solution. Here is the warning: [javac] warning: Supported source version 'RELEASE_6' from annotation processor 'org.hibernate.validator.ap.ConstraintValidationProcessor' less than -source '1.7' And, here are the subsequent warnings/error.

• Automation testing tool for Regression testing of desktop application

  - by user285037

  Hi I am working on a desktop application which uses Infragistic grids. We need to automate the regression tests for same. QTP alone does not support this, we need to buy new plug in for same which my company is not very much interested in. Do we have any open source tool for automating regression testing of desktop application? Application is in Dot net but i do not think it makes much of a difference. Please suggests, i have zeroed in for test complete but again it is licensed one. I need some open source.

• SQLiteDataAdapter Fill exception

  - by Lirik

  I'm trying to use the OleDb CSV parser to load some data from a CSV file and insert it into a SQLite database, but I get an exception with the OleDbAdapter.Fill method and it's frustrating: An unhandled exception of type 'System.Data.ConstraintException' occurred in System.Data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is the source code: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=No;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); // <-- Exception here InsertData(ds, tableName); // <-- Inserts the data into the my SQLite db } } } class Program { static void Main(string[] args) { SQLiteDatabase target = new SQLiteDatabase(); string csvFileName = "D:\\Innovations\\Finch\\dev\\DataFeed\\YahooTagsInfo.csv"; string tableName = "Tags"; target.InsertData(csvFileName, tableName); Console.ReadKey(); } } The "YahooTagsInfo.csv" file looks like this: tagId,tagName,description,colName,dataType,realTime 1,s,Symbol,symbol,VARCHAR,FALSE 2,c8,After Hours Change,afterhours,DOUBLE,TRUE 3,g3,Annualized Gain,annualizedGain,DOUBLE,FALSE 4,a,Ask,ask,DOUBLE,FALSE 5,a5,Ask Size,askSize,DOUBLE,FALSE 6,a2,Average Daily Volume,avgDailyVolume,DOUBLE,FALSE 7,b,Bid,bid,DOUBLE,FALSE 8,b6,Bid Size,bidSize,DOUBLE,FALSE 9,b4,Book Value,bookValue,DOUBLE,FALSE I've tried the following: Removing the first line in the CSV file so it doesn't confuse it for real data. Changing the TRUE/FALSE realTime flag to 1/0. I've tried 1 and 2 together (i.e. removed the first line and changed the flag). None of these things helped... One constraint is that the tagId is supposed to be unique. Here is what the table look like in design view: Can anybody help me figure out what is the problem here? Update: I changed the HDR property from HDR=No to HDR=Yes and now it doesn't give me an exception: OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited"""); I assumed that if HDR=No and I removed the header (i.e. first line), then it should work... strangely it didn't work. In any case, now I'm no longer getting the exception. The new problem is here: public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { conn.Open(); using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } Now the Num rows updated is 0... any hints?

• using java.util.Scanner to read a file byte by byte

  - by openidsucks

  I'm trying to read a one line file character by character using java.util.Scanner. However I'm getting this exception": Exception in thread "main" java.util.InputMismatchException: For input string: "contents of my file" at java.util.Scanner.nextByte(Scanner.java:1861) at java.util.Scanner.nextByte(Scanner.java:1814) at p008.main(p008.java:18) <-- line where I do scanner.nextByte() Here's my code: public static void main(String[] args) throws FileNotFoundException { File source = new File("file.txt"); Scanner scanner = new Scanner(source); while(scanner.hasNext()) { System.out.println((char)scanner.nextByte()); } scanner.close() } Does anyone have any ideas as to what I might be doing wrong? Edit: I realized I wrote hasNext() instead of hasNextByte(). However if I do that it doesn't print out anything.

• Silverlight 4 MediaElement play sound

  - by NealWalters

  I converted a local sound file to a resource, which built this in my XAML: <UserControl.Resources> <my:Uri x:Key="SoundFiles">file:///c:/Audio/HebrewDemo/Shalom.wav</my:Uri> </UserControl.Resources> I did this by pasting a local disk mp3 filename into source, then clicked on the "dot" by source and chose "Extract Value to Resource". When I run, it tells me that "Uri" is not valid, and sure enough, in the Intellisense, I see other elements that start with "uri" but not just URI by itself. In the real world I want to specify a dynamic mp3 file name. For example, I might have a database of foreign language words used for flashcards, I want to play a sound file on a URL. But I thought I would try to walk before running...

• Strange "INavigatorContent" error compiling in 4.0

  - by Stephano

  I've recently decided to try an upgrade to 4.0. The only error I still can't work out is this one: "The children of Halo navigators must implement INavigatorContent" I seem to be getting it on all my ViewStacks that have validators. <mx:ViewStack xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:NumberValidator id="systolicValidator" source="{systolic}" required="true" property="text" minValue="10" maxValue="300" domain="int"/> <mx:NumberValidator id="diastolicValidator" source="{diastolic}" required="true" property="text" minValue="10" maxValue="200" domain="int"/> <mx:TextInput id="systolic"/> <mx:TextInput id="diastolic"/> ... The error gets thrown on the validator tags. My compiler is set to "flex 3 compatibility mode" and my theme is set to Halo (default). This seems like it should be a really straight forward fix, so I hate to spin my wheels on it for too long. Any ideas what I might be missing?

• Programatically determining which node in an XML document caused validation against its XML Schema t

  - by jd1212

  My input is a well-formed XML document and a corresponding XML Schema document. What I would like to do is determine the location within the XML document that causes it to fail validation against the XML Schema document. I could not figure out how to do this using the standard validation approach in Java: SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); Schema schema = schemaFactory.newSchema(... /* the .xsd source */); Validator validator = schema.newValidator(); DocumentBuilderFactory ... DocumentBuilder ... Document document = DocumentBuilder.parse(... /* the .xml source */); try { validator.validate(new DOMSource(document)); ... } catch (SAXParseException e) { ... } I have toyed with the idea of getting at least the line and column number from SAXParseException, but they're always set to -1, -1 on validation error.

• Ball to Ball Collision - Detection and Handling

  - by Simucal

  With the help of the Stack Overflow community I've written a pretty basic-but fun physics simulator. You click and drag the mouse to launch a ball. It will bounce around and eventually stop on the "floor". My next big feature I want to add in is ball to ball collision. The ball's movement is broken up into a x and y speed vector. I have gravity (small reduction of the y vector each step), I have friction (small reduction of both vectors each collision with a wall). The balls honestly move around in a surprisingly realistic way. I guess my question has two parts: What is the best method to detect ball to ball collision? Do I just have an O(n^2) loop that iterates over each ball and checks every other ball to see if it's radius overlaps? What equations do I use to handle the ball to ball collisions? Physics 101 How does it effect the two balls speed x/y vectors? What is the resulting direction the two balls head off in? How do I apply this to each ball? Handling the collision detection of the "walls" and the resulting vector changes were easy but I see more complications with ball-ball collisions. With walls I simply had to take the negative of the appropriate x or y vector and off it would go in the correct direction. With balls I don't think it is that way. Some quick clarifications: for simplicity I'm ok with a perfectly elastic collision for now, also all my balls have the same mass right now, but I might change that in the future. In case anyone is interested in playing with the simulator I have made so far, I've uploaded the source here (EDIT: Check the updated source below). Edit: Resources I have found useful 2d Ball physics with vectors: 2-Dimensional Collisions Without Trigonometry.pdf 2d Ball collision detection example: Adding Collision Detection Success! I have the ball collision detection and response working great! Relevant code: Collision Detection: for (int i = 0; i < ballCount; i++) { for (int j = i + 1; j < ballCount; j++) { if (balls[i].colliding(balls[j])) { balls[i].resolveCollision(balls[j]); } } } This will check for collisions between every ball but skip redundant checks (if you have to check if ball 1 collides with ball 2 then you don't need to check if ball 2 collides with ball 1. Also, it skips checking for collisions with itself). Then, in my ball class I have my colliding() and resolveCollision() methods: public boolean colliding(Ball ball) { float xd = position.getX() - ball.position.getX(); float yd = position.getY() - ball.position.getY(); float sumRadius = getRadius() + ball.getRadius(); float sqrRadius = sumRadius * sumRadius; float distSqr = (xd * xd) + (yd * yd); if (distSqr <= sqrRadius) { return true; } return false; } public void resolveCollision(Ball ball) { // get the mtd Vector2d delta = (position.subtract(ball.position)); float d = delta.getLength(); // minimum translation distance to push balls apart after intersecting Vector2d mtd = delta.multiply(((getRadius() + ball.getRadius())-d)/d); // resolve intersection -- // inverse mass quantities float im1 = 1 / getMass(); float im2 = 1 / ball.getMass(); // push-pull them apart based off their mass position = position.add(mtd.multiply(im1 / (im1 + im2))); ball.position = ball.position.subtract(mtd.multiply(im2 / (im1 + im2))); // impact speed Vector2d v = (this.velocity.subtract(ball.velocity)); float vn = v.dot(mtd.normalize()); // sphere intersecting but moving away from each other already if (vn > 0.0f) return; // collision impulse float i = (-(1.0f + Constants.restitution) * vn) / (im1 + im2); Vector2d impulse = mtd.multiply(i); // change in momentum this.velocity = this.velocity.add(impulse.multiply(im1)); ball.velocity = ball.velocity.subtract(impulse.multiply(im2)); } Source Code: Complete source for ball to ball collider. Binary: Compiled binary in case you just want to try bouncing some balls around. If anyone has some suggestions for how to improve this basic physics simulator let me know! One thing I have yet to add is angular momentum so the balls will roll more realistically. Any other suggestions? Leave a comment!

• JSF Portlets in Liferay on JBoss

  - by JBirch

  I'm currently looking at working with and deploying JSF portlets into Liferay 6.0.5, sitting on JBoss 5.1.0. I ran into a lot of trouble trying to port some JSF-y/Seam-y/EJB-y stuff I had lying around, so I thought I'd start simple and work my way up. I could generate generic portlets using the NetBeans Maven archetype for Liferay portlets absolutely fine, but it's rather irrelevant because I wanted JSF portlets I took an example JSF portlet from http://www.liferay.com/downloads/liferay-portal/community-plugins/-/software_catalog/products/5546866 and attempted to deploy into a clean, vanilla installation of Liferay 6.0.5/JBoss 5.1.0 to no avail. The log messages are reproduced at the end of this. This particular example was actually tested for GlassFish and Tomcat, so it's not particularly helpful considering I'm deplying into JBoss. I tried ripping it apart and removing the jsf implementation contained within as there is a jsf implementation shipped with JBoss (Mojarra 1.2_12, in this case). 03:16:17,173 INFO [PortletAutoDeployListener] Copying portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war Expanding: /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war into /tmp/20110201031617188 Copying 1 file to /tmp/20110201031617188/WEB-INF Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 47 files to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Copying 1 file to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Deleting directory /tmp/20110201031617188 03:16:20,075 INFO [PortletAutoDeployListener] Portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war copied successfully.

• .Net Intermittent System.Web.Services.Protocols.SoapHeaderException

  - by ScottE

  We have a .net 3.5 web app that consumes third party web services. The proxy was created by adding a web reference to their wsdl. This proxy is not compiled. Our error logging is picking up frequent but intermittent exceptions: An exception of type 'System.Web.Services.Protocols.SoapHeaderException' occurred and was caught If I follow the url to the page that generated the exception, I can't recreate it.

We had MS support involved today, and they looked at some traces and network captures. The web service host does round-robin DNS, and they may be responding on a different IP address for the syn syn/ack from one ip, and the next from a different ip. This is not good. This is likely quite specific to our situation, but perhaps it applies to others as well. Microsoft Network Monitor and an application trace got us the information we needed.

• Automapper use in a MVVM application

  - by Echiban

  I am building a MVVM application. The model / entity (I am using NHibernate) is already done, and I am thinking of using AutoMapper to map between the ViewModel and Model. However this clause scares the jebus out of me: (from http://www.lostechies.com/blogs/jimmy_bogard/archive/2009/01/22/automapper-the-object-object-mapper.aspx) Blockquote AutoMapper enforces that for each type map (source/destination pair), all of the properties on the destination type are matched up with something on the source type To me, the logical choice is to map from model to viewmodel, (and I'll let viewmodel manually assign to model), but the quote basically kills the idea since the viewmodel will definitely have properties that don't exist on the model. How have you been using Automapper in a MVVM app? Please help!

• libevent, windows and .NET programming

  - by Chris

  I experiment with a lot of open source software and I've noticed a fair amount of server type applications in the open source world use libevent to facilitate event-based processing rather than spawn multiple threads to handle requests. I also do a lot of .NET programming (it's my core job function), and I'm interested in learning how libevent relates to the .NET event model. Are events in .NET the equivalent of libevent for C programs? Should I try to learn libevent and attempt to use it in custom .NET server applications or is using the standard .NET event model basically the same thing?

• Ado.net performance:What does SNIReadSync do?

  - by Beatles1692

  We have a query that takes 2 seconds to run in Sql Server Management Studio but it takes 13 seconds to be shown on a client screen. I used dotTrace to profile my source code and noticed there is this SNIReadSync method (part of ADO.net assemblies)that takes a lot of time to do its job(9 seconds).I ran my source over server so I could omit the network effects and the result was the same. It doesn't matter if I'm using OleDBConnection or SqlConnection. It doesn't matter if I'm using a DataReader or a DataSet. Connection pooling does not solve this issue(as my result shows). I googled this issue and I couldn't find an answer to the question that what this method is actually doing and how we can improve it. here's what I found on StakOverFlow that's not helpful either: http://stackoverflow.com/questions/1610874/snireadsync-executing-between-120-500-ms-for-a-simple-query-what-do-i-look-for

• Option Trading: Getting the most out of the event session options

  - by extended_events

  You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!
