• Throwing Exception in CTOR and Smart Pointers

  - by David Relihan

  Is it OK to have the following code in my constructor to load an XML document into a member variable - throwing to caller if there are any problems: MSXML2::IXMLDOMDocumentPtr m_docPtr; //member Configuration() { try { HRESULT hr = m_docPtr.CreateInstance(__uuidof(MSXML2::DOMDocument40)); if ( SUCCEEDED(hr)) { m_docPtr->loadXML(CreateXML()); } else { //throw exception to caller } } catch(...) { //throw exception to caller } } Based on Scott Myers RAII implementations in More Effective C++ I believe I am alright in just allowing exceptions to be thrown from CTOR as I am using a smart pointer(IXMLDOMDocumentPtr). Let me know what you think....

• Alright to truncate database tables when also using Hibernate?

  - by Marcus

  Is it OK to truncate tables while at the same time using Hibernate to insert data? We parse a big XML file with many relationships into Hibernate POJO's and persist to the DB. We are now planning on purging existing data at certain points in time by truncating the tables. Is this OK? It seems to work fine. We don't use Hibernate's second level cache. One thing I did notice, which is fine, is that when inserting we generate primary keys using Hibernate's @GeneratedValue where Hibernate just uses a key value one greater than the highest value in the table - and even though we are truncating the tables, Hibernate remembers the prior value and uses prior value + 1 as opposed to starting over at 1. This is fine, just unexpected. Note that the reason we do truncate as opposed to calling delete() on the Hibernate POJO's is for speed. We have gazillions of rows of data, and truncate is just so much faster.

• Bind multiple request parameters to one object in Spring 3

  - by Max

  Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

• How to have onSearchRequested not open a web browser.

  - by pcm2a

  I have a button in my app. When it is pressed I call the onSearchRequested() method. When this is called the stock search box comes up so the user can type some junk in there. When they press "Go" I need the results returned back to my application but instead the stock browser is opened and a google search is performed. How can I tell it to return the results to my application instead. I've tried these items in my manifest.xml file: <meta-data android:name="android.app.default_searchable" android:value=".MainActivity" /> <activity android:name=".MainActivity" android:launchMode="singleTop" <intent-filter> <action android:name="android.intent.action.SEARCH" /> </intent-filter> I've also tried to capture the result in my onCreate with this: Intent intent = getIntent(); if (Intent.ACTION_SEARCH.equals(intent.getAction()))

• NDepend: How to not display 'tier' assemblies in dependency graph?

  - by Edward Buatois

  I was able to do this in an earlier version of nDepend by going to tools-options and setting which assemblies would be part of the analysis (and ignore the rest). The latest version of the trial version of nDepend lets me set it, but it seems to ignore the setting and always analyze all assemblies whether I want it to or not. I tried to delete the "tier" assemblies by moving them over to the "application assemblies" list, but when I delete them out of there, they just get added back to the "tier" list, which I can't ignore. I don't want my dependency graph to contain assemblies like "system," "system.xml," and "system.serialization!" I want only MY assemblies in the dependency graph! Or is that a paid-version feature now? Is there a way to do what I'm talking about?

• Is there a Java API for creating a XHTML document?

  - by Bedwyr Humphreys

  I want to provide a simple XHTML representation of each of the resources in a REST web service. At the moment i'm using a StringBuilder to generate these which is both tedious and error prone. I don't see these changing after I publish the service but the process of coding each is a bit painful. Is there a XHTML document writer api? Should I just use an XML writer? Which one? Should I just roll my own basic HTML document class - doctype is the same each time, i just need to set the title, metatags and body content, most of which (but not all content) is already in HTML for the GETs. Or should I just use StringBuilder and stop whining? ;) Thanks.

• Serializing C# objects to DB

  - by Robert Koritnik

  I'm using a DB table with various different entities. This means that I can't have an arbitrary number of fields in it to save all kinds of different entities. I want instead save just the most important fields (dates, reference IDs - kind of foreign key to various other tables, most important text fields etc.) and an additional text field where I'd like to store more complete object data. the most obvious solution would be to use XML strings and store those. The second most obvious choice would be JSON, that usually shorter and probably also faster to serialize/deserialize... And is probably also faster. But is it really? My objects also wouldn't need to be strictly serializable, because JsonSerializer is usually able to serialize anything. Even anonymous objects, that may as well be used here. What would be the most optimal solution to solve this problem?

• Invoke webservice using jaxws when the wsdl has more than one service

  - by Hugo Palma

  I'm trying to get hold of the FindService on this wsdl using jaxws. I generated the classes just fine using wsimport. But when i do: FindService findService = new FindService(); i get the exception: Exception in thread "main" javax.xml.ws.WebServiceException: {http://s.mappoint.net/mappoint-30/}FindService is not a valid service. Valid services are: {http://s.mappoint.net/mappoint-30/}CommonService So, it seems that jaxws is only finding CommonService in the wsdl which is the first one declared in it. Any idea how i can use the FindService ? Thanks.

• JSF2 - Why does render response not rerender component setting?

  - by fekete-kamosh

  From the tutorial: "If the request is a postback and errors were encountered during the apply request values phase, process validations phase, or update model values phase, the original page is rendered during Render response phase" (http://java.sun.com/javaee/5/docs/tutorial/doc/bnaqq.html) Does it mean that if view is restored in "Restore View" phase and then any apply request/validation/update model phase fails and skips to "Render response" that Render response only passes restored view without any changes to client?

• Oracle Application Server 10.1.3.5 Security issue.

  - by Marius Bogdan IONESCU

  Hello! we are tying to port a J2EE app from OAS 9.0.4 (working perfectly) on OAS 10.1.3.5 the reson we do that is because we need the app compiled with java 1.5 and OAS 10.1.3.5 would be the single major version supporting that binaries which has oc4j/orion kernel. The issue is that the security constraints in matter of user/group/role are not read by the app server, and instead of asking for these sets of users, i have to use the oc4jadmin instead the selected users for auth. All xml files needed for describing these sets of rules are being checked with the OAS book, and it seems they are correctly filled in... anybody has an idea about this?

• Spring Roo unable to generate Selenium tests because of Xerces error

Does anyone know of a clear way to remove jars from the classpath? Has anyone encountered this Roo problem before and solved it another way?

• how can I retrieve an html document from a url from javascript?

  - by Matt

  Hi, I have a url and I want to retrieve the html dom generated when going to the url (all the code for the page) in a javascript variable. How can I do this? I'm guessing an html get or post? Can anyone give an example with jQuery? Every time I do a $.get or $.post like this: $.get("http://www.google.ca", function(result) { alert(result); alert($(result).html()); }); $.post("http://www.google.ca", function(result) { alert(result); alert($(result).html()); }, "xml"); the first alert in each call comes up blank and the second comes up as null. Any ideas? Thanks, Matt

• Tree View Control problem with render Control function

  - by vikas

  I am using TreeView Control in Asp.net. I have placed this control inside a panel. The tree control is completely binded (we don’t want populate on demand) with an Xmldatasource during a callback and then I call Panel.renderControl to return the response (HTML) to the client side callback handler. Problem: 1. The tree expand/collapse (on click of plus sign) is causing postback whereas when I normally bind a tree with xml during postback and without using renderControl of container control, the expand/collapse (on click of plus sign) is being handled at client side.

• How to rewrite the URL

  - by Kalpana

  I have a small application built using Seam 2.2, Richfaces 3.3, JBoss 5.1. Most of the page navigation adds the request parameters to the target URL. I would like to hide parameters to be hidden to the customer who is using the application (e.g. I would expect the URL to be something like "http://localhost:8080/books/Book.seam". The parameters (userId, orderId and cmId) are currently mapped to the backend bean via Book.page.xml. How do I prevent the request parameters from showing up in the browser URL, as it also allows the customer to manipulate the URL. We did look at seam URL re-writing feature, it talked about manipulating say the primary key id in a REST format, not sure how to accomplish something more complex like the above use case in a elegant fashion.

• C#: How do I get the path of the assembly the code is in?

  - by George Mauer

  Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code. Basically my unit test needs to read some xml test files which are located relative to the dll. I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else. Edit: People seem to be misunderstanding what I'm asking. My test library is located in say c:\projects\myapplication\daotests\bin\Debug\daotests.dll and I would like to get the "*c:\projects\myapplication\daotests\bin\Debug*" path. The three suggestions so far fail me when I run from the MbUnit Gui: Console.Out.Write(Environment.CurrentDirectory) gives c:\Program Files\MbUnit Console.Out.Write(System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location) gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll Console.Out.Write(System.Reflection.Assembly.GetExecutingAssembly().Location) gives the same as the previous

• Using the Antenna and J2ME Polish preprocessors interchangeably and setting a variable value

  - by walter

  I have J2ME code, which I want to be able to compile using the J2ME Polish preprocessor or the wtkpreprocessor (antenna). They mostly use the same directives so it usually works, but ... When I want to insert an URL value in the Java code this gives a problem. In Antenna the code would look like this: //#ifdef my.url //# System.out.println("My Url"); //#expand String location = "%my.url%"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif and in J2ME Polish it would look like this: //#ifdef my.url:defined //# System.out.println("My Url"); //#= String location = "${my.url}"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif I want some way in which I can use the preprocessors interchangeably and still be able to set the url in the build.xml, any ideas?

  - by mauvo

  I want MyCanvas to draw lines on itself, but they seem to be drawn behind the background. What's going on and how should I do this? Main.mxml <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:my="*"> <my:MyCanvas width="300" height="300" id="myCanvas"></my:MyCanvas> <mx:Button label="Draw" click="myCanvas.Draw();"></mx:Button> </mx:Application> MyCanvas.as package { import mx.containers.Canvas; public class MyCanvas extends Canvas { public function MyCanvas() { this.setStyle("backgroundColor", "white"); } public function Draw():void { graphics.lineStyle(1); graphics.moveTo( -10, -10); graphics.lineTo(width + 10, height + 10); } } } Thanks.

• Alternative for PHPlivedocx?

  - by Derek

  Hello, Is there any other free alternatives to PHPliveDocx? I would like to create a Word document based on templates and user inputted data. The template will resides on the server and the client(online or c# windows application) will be used to collect user input. Once data has been collected, server-side script(PHP) will be used to generate a Word document. So far I have only found phplivedocx. However I'm not very comfortable at consuming web services from a server that I have no control over with (am I worrying too much?). I have also thought about using client to do the work (c# windows application, Open Office XML). But I'm not sure that's the right way of doing things. Any guidance/help will be really appreciated! Thanks!
