  • How can I stop rails validating xml?

    - by Andrei T. Ursan
    I'm submitting to a rails webservice the following message: xmlPostData = "<message> <message-text>" + MESSAGE_WITH_XML + "</message-text> <name>" + subject + "</name> <f1>" + toPhone + "</f1> <f2>" + fromPhone + "</f2> </message>"; The problem is the the field with contain a text with XML data, is a workaround but I need to be able to submit that xml to the db and get it from there. Can I stop rails validating and replacing my xml in json format? this is how it looks: --- !map:HashWithIndifferentAccess smil: !map:HashWithIndifferentAccess head: !map:HashWithIndifferentAccess layout: !map:HashWithIndifferentAccess root_layout: !map:HashWithIndifferentAccess height: &quot;600&quot; background_color: white width: &quot;800&quot; type: text/smil-basic-layout body: !map:HashWithIndifferentAccess par: !map:HashWithIndifferentAccess text: !map:HashWithIndifferentAccess left: &quot;33&quot; begin: &quot;33&quot; dur: &quot;33&quot; val: 34343434343434343aaaaaaa height: &quot;33&quot; width: &quot;33&quot; top: &quot;33&quot; And this is the ruby method from the rails webservice: # POST /messages # POST /messages.xml def create @message = Message.new(params[:message]) respond_to do |format| if @message.save flash[:notice] = 'Message was successfully created.' format.html { redirect_to(@message) } format.xml { render :xml => @message, :status => :created, :location => @message } else format.html { render :action => "new" } format.xml { render :xml => @message.errors, :status => :unprocessable_entity } end end end Is a workaround but for the moment this has to work ...

  • Problem connecting to Apache Derby using Hibernate configuration file in Netbeans (ERROR XSDB6)

    - by me_here
    I've created a local Apache Derby database in Netbeans, but am having problems when I try and autogenerate the POJO files, using the "Hibernate Reverse Engineering Wizard". My Hibernate configuration (generated by Netbeans from the database connection, then I added a few bits): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Default Netbeans generated parameters --> <property name="hibernate.connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="hibernate.connection.url">jdbc:derby:C:/CerealDatabase</property> <property name="hibernate.connection.username">cerealuser</property> <property name="hibernate.connection.password">cerealpass</property> <!-- Additional parameters --> <property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.default_schema">CEREALUSER</property> </session-factory> </hibernate-configuration> When I try and generate the POJOs using this configuration file, I get the message to check my configuration file, and the derby.log gives the errors: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: ERROR XSDB6: Another instance of Derby may have already booted the database C:\CerealDatabase. I've closed any other connections to the database before trying this, and there is no "db.lck" lock file at the time, which indicates there are no connections to the database as I understand it. Does anyone have any ideas? Help gratefully received.

  • PDCurses TUI C++ Win32 console app - Access violation reading location

    - by Bach
    I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime, which suggests a bad pointer: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

  • How to inject a Session Bean into a Message Driven Bean?

    - by Hank
    Hi guys, I'm reasonably new to JEE, so this might be stupid.. bear with me pls :D I would like to inject a stateless session bean into a message-driven bean. Basically, the MDB gets a JMS message, then uses a session bean to perform the work. The session bean holds the business logic. Here's my Session Bean: @Stateless public class TestBean implements TestBeanRemote { public void doSomething() { // business logic goes here } } The matching interface: @Remote public interface TestBeanRemote { public void doSomething(); } Here's my MDB: @MessageDriven(mappedName = "jms/mvs.TestController", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class TestController implements MessageListener { @EJB private TestBean testBean; public TestController() { } public void onMessage(Message message) { testBean.doSomething(); } } So far, not rocket science, right? Unfortunately, when deploying this to glassfish v3, and sending a message to the appropriate JMS Queue, I get errors that glassfish is unable to locate the TestBean EJB: java.lang.IllegalStateException: Exception attempting to inject Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session into class mvs.test.TestController Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session into class mvs.test.TestController Caused by: javax.naming.NamingException: Lookup failed for 'java:comp/env/mvs.test.TestController/testBean' in SerialContext [Root exception is javax.naming.NamingException: Exception resolving Ejb for 'Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session' . Actual (possibly internal) Remote JNDI name used for lookup is 'mvs.test.TestBean#mvs.test.TestBean' [Root exception is javax.naming.NamingException: Lookup failed for 'mvs.test.TestBean#mvs.test.TestBean' in SerialContext [Root exception is javax.naming.NameNotFoundException: mvs.test.TestBean#mvs.test.TestBean not found]]] So my questions are: - is this the correct way of injecting a session bean into another bean (particularly a message driven bean)? - why is the naming lookup failing? Thanks for all your help! Cheers, Hank

  • How to avoid saving a blank model which attributes can be blank

    - by auralbee
    Hello people, I have two models with a HABTM association, let´s say book and author. class Book has_and_belongs_to_many :authors end class Author has_and_belongs_to_many :books end The author has a set of attributes (e.g. first-name,last-name,age) that can all be blank (see validation). validates_length_of :first_name, :maximum => 255, :allow_blank => true, :allow_nil => false In the books_controller, I do the following to append all authors to a book in one step: @book = Book.new(params[:book]) @book.authors.build(params[:book][:authors].values) My question: What would be the easiest way to avoid the saving of authors which fields are all blank to prevent too much "noise" in the database? At the moment, I do the following: validate :must_have_some_data def must_have_some_data empty = true hash = self.attributes hash.delete("created_at") hash.delete("updated_at") hash.each_value do |value| empty = false if value.present? end if (empty) errors.add_to_base("Fields do not contain any data.") end end Maybe there is an more elegant, Rails-like way to do that. Thanks.

  • Windows 7 64 Bit - ODBC32 - Legacy App Problem

    - by Arturo Caballero
    Good day StackOverFlowlers, I´m a little stuck (really stuck) with an issue with a legacy application on my organization. I have a Windows 7 Enterprise 64 Bit machine, Access 2000 Installed and the Legacy App (Is built with something like VB but older) The App uses System ODBC in order to connect to a SQL 2000 DataBase on a Remote Server. I created the ODCB using C:\Windows\SysWOW64\odbcad32.exe app in order to create a System DSN. I did not use the Windows 7 because it is not visible to the Legacy App. I tested the ODBC connection with Access and worked ok, I can access the remote database. Then I run the legacy App as Administrator and the App can see the ODBC, but I´m getting errors on credential validation and I´m getting this error: DIAG [08001] [Microsoft][ODBC SQL Server Driver][Multi-Protocol]SQL Server does not exist or access denied. (17) DIAG [01000] [Microsoft][ODBC SQL Server Driver][Multi-Protocol]ConnectionOpen (Connect()). (53) DIAG [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed (0) I use Trusted Connection on the ODBC in order to validate the user by Domain Controller. I think that the credentials are not being sent by the Legacy App to the ODBC, or something like that. I don´t have the source code of the Legacy App in order to debug the connection. Also, I turned off the Firewall. Any ideas?? Thanks in advance!

  • Data loss when downloading data from LDAP server

    - by Ricky D'Amelio
    Hi there. This question comes from a previous one I asked about handling NSData objects: http://stackoverflow.com/questions/2453785/converting-nsdata-to-an-nsstring-representation-is-failing. I have reached the point where I am taking an NSImage, turning it into NSData and uploading those data bytes to the LDAP server. I am doing this like so; //connected successfully to LDAP server above... struct berval photo_berval; struct berval *jpegPhoto_values[2]; photo_berval.bv_len = [photo length]; photo_berval.bv_val = [photo bytes]; jpegPhoto_values[0] = &photo_berval; jpegPhoto_values[1] = NULL; mod.mod_type = "jpegPhoto"; mod.mod_op = LDAP_MOD_REPLACE|LDAP_MOD_BVALUES; mod.mod_bvalues = jpegPhoto_values; mods[0] = &mod; mods[1] = NULL; //perform the modify operation rc = ldap_modify_ext_s(ld, givenModifyEntry, mods, NULL, NULL); That happens with no errors, and you can see a big blob of data when you're in the command line. My problem is, when I go to access the same data at a later stage, I am getting an image file back that's about 120 times smaller than the original image. //find the jpegPhoto attribute photoA = ldap_first_attribute(ld, photoE, &photoBer); while (strcasecmp(photoA, "jpegphoto") != 0) { photoA = ldap_next_attribute(ld, photoE, photoBer); } //get the value of the attribute if ((list_of_photos = ldap_get_values_len(ld, photoE, photoA)) != NULL) { //get the first JPEG photo_data = *list_of_photos[0]; selectedPictureData = [NSData dataWithBytes:&photo_data length:sizeof(photo_data)]; [selectedPictureData writeToFile:@"/Users/username/Desktop/Photo 2.jpg" atomically:YES]; NSLog (@"%@", selectedPictureData); Has anyone successfully done this before or can anyone see what I might be doing wrong? I appreciate anyone's help. Sorry to post so many questions! Ricky.

  • Rendering a control generates security exception in .Net 4

    - by Jason Short
    I am having a problem with code that worked fine in .Net 2 giving this error under .Net 4. Build (web): Inheritance security rules violated while overriding member: 'Controls.RelatedPosts.RenderControl(System.Web.UI.HtmlTextWriter)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden. This is in DotNetBlogEngine. There were several other security demands in the code that .Net 4 didn't seem to like. I followed some of the advice I found on blogs (and here) and got rid of all the other errors. But this one still eludes me. The Main blogengine core dll is not set for security demands anylonger and is compiled for .Net 4 as well. This error is in the website side attempting to use the dll. There are controls that call a RenderControl method taking an HtmlTextWriter. Apparently the text writer now has some soft of security attributes set on it. Each of the controls implements a custom interface ( public interface ICustomFilter ), there are no security permissions present or demands. The site is running full trust on my local dev machine.

  • Solutions for working with multiple branches in ASP.Net

    - by Corey McKinnon
    At work, we are often working on multiple branches of our product at one time. For example, right now, we have a maintenance branch, a branch with code just going to QA, and a branch for a new major initiative, that won't be merged for some time now. Our web project is set up to use IIS, so every time we switch to a different branch, we have to go in to IIS Admin and change the path on the virtual directory, then reset IIS, and sometimes even restart Visual Studio, to avoid getting build errors. Is there any way to simplify this, other than not having our web project set up as a virtual directory? I'm not sure we want to make that change at this point. What do you do to make this easier, assuming you do this? Corey @RedWolves, virtual machines would definitely work, but I'm not sure it would be any simpler, especially for some of the other developers on my team, which is partly why I'm looking for more simplicity. @Dan, we're not able to change source control providers, unfortunately. @pix0r, that's something I'll try when I get back to work. Thanks for the suggestion. @Haacked, I'll have to give that a try too, but I think we have some issues with why that won't work (I can't remember exactly why right now; this application was originally written in .Net 1.1, pre-Cassini, and I can't remember if we tried it when we upgraded to 2.0 or not). Thanks all for the responses so far.

  • Asp.Net MVC Tutorial Unit Tests

    - by Nicholas
    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out if (cart.Lines.Count == 0) { ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); return View(); } // Invoke model binding manually if (TryUpdateModel(cart.ShippingDetails, form.ToValueProvider())) { orderSubmitter.SubmitOrder(cart); cart.Clear(); return View("Completed"); } else // Something was invalid return View(); } with the following unit test [Test] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var result = controller.CheckOut(cart, new FormCollection { { "Name", "" } }); // Assert Assert.IsEmpty(result.ViewName); Assert.IsFalse(result.ViewData.ModelState.IsValid); } I have resolved any issues surrounding 'TryUpdateModel' by upgrading to ASP.NET MVC 2 (Release Candidate 2) and the website runs as expected. The associated error messages are: *Tests.CartControllerTests.Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error: System.ArgumentNullException : Value cannot be null. Parameter name: controllerContext* and the more detailed at System.Web.Mvc.ModelValidator..ctor(ModelMetadata metadata, ControllerContext controllerContext) at System.Web.Mvc.DefaultModelBinder.OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.DefaultModelBinder.BindComplexModel(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider) at WebUI.Controllers.CartController.CheckOut(Cart cart, FormCollection form) Has anyone run into a similar issue or indeed got the test to pass?

  • Load dll's from Environment Variable Path from a service

    - by Paulo Manuel Santos
    We install Matlab Runtime on a machine, then we restart a .net windows service that invokes methods from the Matlab Runtime. The problem is that we receive TypeInitializationException errors until we restart windows. We think this happens because Environment Variables are not changed on services until restart and Matlab uses the %Path% variable to reference it's core DLL's. My question is, do you think I can change the %Path% variable so that Matlab will use it when referencing the core dll's for it's engine? Or is it possible to add a directory to the runtime DLL loading mechanism of .NET so that those Matlab core dll's would be referenced correctly without restarting the machine? Here is the exception we get System.TypeInitializationException: The type initializer for 'MatlabCalculation.Calculation' threw an exception. ---> System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'mclmcrrt710.dll': Kan opgegeven module niet vinden.

  • IE9 selectAllChildren on an out-of-view element

    - by MrSlayer
    I am trying to replicate a service that is provided by Tynt.com that appends some text to a user's selection when copying. I understand that users don't particularly like this, but it is a client's request to append the URL and copyright notice whenever a user copies something from their website. In current browsers, I am able to do this by creating a DOM element, adding the selected text, appending the copyright text and then selecting the new node: var newSelection = document.createElement( 'div' ); newSelection.style.cssText = "height: 1px; width: 1px; overflow: hidden;"; if( window.getSelection ) { var selection = window.getSelection( ); if( selection.getRangeAt ) { var range = selection.getRangeAt( 0 ); newSelection.appendChild( range.cloneContents( ) ); appendCopyright( ); document.body.appendChild( newSelection ); selection.selectAllChildren( newSelection ); // ... remove element, return selection } } In IE9, this errors out on the selection.selectAllChildren( newSelection ) statement and I was able to figure out that this is because newSelection was effectively "hidden" from the viewport due to the styles applied in the second line above. Commenting that out works, but obviously the new node is shown to the end user. It appears that this was resolved in later versions of IE, but I am having trouble coming up with a workaround that is sufficient for IE9, a browser that I need to support. I've tried a variety of alternatives, like setting visibility: hidden;, positioning it off-screen, and trying some alternative selection functions, but they each present different problems. The error thrown by IE is: SCRIPT16389: Unspecified error.

  • My AJAX is only firing once,

    - by sea_1987
    Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

  • WCF- "The underlying connection was closed: The connection was closed unexpectedly"

    - by SumGuy
    Hi there. I'm recieving that wonderfuly ambiguous error message when using one of my webmethods on my WCF webservice. As that error message doesn't provide any explanation whatsoever allow me to post my theory. I believe it may have something to do with the return type I'm using I have a Types DLL which is refrenced in both the webservice and the client. In this DLL is the base class ExceptionMessages. There is a child of this class called DrawingExcepions. Here is some code: public class ExceptionMessages { public object[] ReturnValue { get; set; } } public class DrawingExceptions : ExceptionMessages { private List<DrawingException> des = new List<DrawingException>(); } public class DrawingException { public Exception ExceptionMsg { get; set; } public List<object> Errors { get; set; } } The using code: [OperationContract] ExceptionMessages createNewBom(Bom bom, DrawingFiles dfs); public ExceptionMessages createNewBOM(Bom bom, DrawingFiles dfs) { return insertAssembly(bom, dfs); } public DrawingExceptions insertAssembly(Bom bom, DrawingFiles dfs) { DrawingExceptions des = new DrawingExceptions(); foreach (DrawingFile d in dfs.drawingFiles) { DrawingException temp = insertNewDrawing(bom, d); if (temp != null) des.addDrawingException(temp); if (d.Child != null) des.addDrawingException(insertAssembly(bom, d.Child)); } return des; } Returns to: ExceptionMessages ems = client.createNewBom(bom, currentDFS); if (ems is DrawingExceptions) { } Basically the return type from the webmethod is ExceptionMessages however I would usually be sending the child class back instead. My only idea is that it's the child that's causing the error but as far as I've read, this should have no effect. Has anyone got any ideas what could be going wrong here? If any more info is required, just ask :) Thanks.

  • dojo.io.iframe erroring when uploading a file

    - by Grant Collins
    Hi, Hit an interesting problem today when trying to upload an image file < 2MB using dojo.io.iframe. My function to process the form is called, but before the form is posted to the server I am getting the following error: TypeError: ifd.getElementsByTagName("textarea")[0] is undefined My function that is used to action the post of the form is : function uploadnewlogo(){ var logoDiv = dojo.byId('userlogo'); var logoMsg = dojo.byId('uploadmesg'); //prep the io frame to send logo data. dojo.io.iframe.send({ url: "/users/profile/changelogo/", method: "post", handleAs: "text", form: dojo.byId('logoUploadFrm'), handle: function(data,ioArgs){ var response = dojo.fromJson(data); if(response.status == 'success'){ //first clear the image //dojo.style(logoDiv, "display", "none"); logoDiv.innerHTML = ""; //then we update the image logoDiv.innerHTML = response.image; }else if(response.status == 'error'){ logoMsg.innerHTML = data.mesg; }else{ logoMsg.innerHTML = '<div class="error">Whoops! We can not process your image.</div>'; } }, error: function(data, ioArgs){ logoMsg.innerHTML = '<div class="error">' + data + '</div>'; } }); } The form is very basic with just a File input component and a simple button that calls this bit of javascript and dojo. I've got very similar code in my application that uploads word/pdf documents and that doesn't error, but for some reason this does. Any ideas or pointers on what I should try to get this to work without errors? Oh I'm using php and Zend framework for the backend if that has anything to do with it, but I doubt it as it's not even hitting the server before it fails. Many thanks, Grant

  • C++: Check istream has non-space, non-tab, non-newline characters left without extracting chars

    - by KRao
    I am reading a std::istream and I need to verify without extracting characters that: 1) The stream is not "empty", i.e. that trying to read a char will not result in an fail state (solved by using peek() member function and checking fail state, then setting back to original state) 2) That among the characters left there is at least one which is not a space, a tab or a newline char. The reason for this is, is that I am reading text files containing say one int per line, and sometimes there may be extra spaces / new-lines at the end of the file and this causes issues when I try get back the data from the file to a vector of int. A peek(int n) would probably do what I need but I am stuck with its implementation. I know I could just read istream like: while (myInt << myIstream) {...} //Will fail when I am at the end but the same check would fail for a number of different conditions (say I have something which is not an int on some line) and being able to differentiate between the two reading errors (unexpected thing, nothing left) would help me to write more robust code, as I could write: while (something_left(myIstream)) { myInt << myIstream; if (myStream.fail()) {...} //Horrible things happened } Thank you!

    I'm trying to install the paperclip plugin with the following command: ruby script/plugin install git://github.com/thoughtbot/paperclip.git But I'm getting some errors: ruby script/plugin install git://github.com/thoughtbot/paperclip.git --force svn: '/home/app/vendor/plugins' is not a working copy /usr/lib/ruby/1.8/open-uri.rb:32:in `initialize': No such file or directory - git://github.com/thoughtbot/paperclip.git (Errno::ENOENT) from /usr/lib/ruby/1.8/open-uri.rb:32:in `open_uri_original_open' from /usr/lib/ruby/1.8/open-uri.rb:32:in `open' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:863:in `fetch_dir' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:857:in `fetch' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:856:in `each' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:856:in `fetch' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:219:in `install_using_http' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:169:in `send' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:169:in `install' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:734:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:732:in `each' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:732:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:447:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:463:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:871 from script/plugin:3:in `require' from script/plugin:3 Is it because I'm using a old rails version?

  • Loading Liferay Properties from Spring IoC container (to get jdbc connection parameters)

    - by mox601
    I'm developing some portlets for Liferay Portal 5.2.3 with bundled tomcat 6.0.18 using Spring IoC container. I need to map the User_ table used in Liferay database to an entity with Hibernate, so I need to use two different dataSources to separate the liferay db from the db used by portlets. My jdbc.properties has to hold all connection parameters for both databases: no problem for the one used by portlets, but I am having issues determining which database uses liferay to hold its data. My conclusion is that i should have something like this: liferayConnection.url=jdbc:hsqldb:${liferay.home}/data/hsql/lportal in order to get the database url dynamically loaded, according to Liferay properties found in portal-ext.properties. (Or, better, load the whole portal-ext.properties and read database properties from there). The problem is that the placeholder is not resolved: Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'liferayDataSource' defined in class path resource [WEB-INF/applicationContext.xml]: Could not resolve placeholder 'liferay.home' To dodge this problem I tried to load explicitly portal-ext.properties with a Spring bean: <bean id="liferayPropertiesConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="../../portal-ext.properties"/> but no luck: liferay.home is not resolved but there aren't other errors. How can I resolve the placeholder defined by Liferay? Thanks

  • Problems with zend-tool reporting that providers are not valid

    - by Mario
    I have recently setup XAMPP 1.7.3 and ZendFramework 1.10.4 on a new computer and many of the commands that I normally use now fail. Here are the steps I used to setup and test ZF. First I added the ZF library folder (C:\xampp\php\ZendFramework-1.10.4\library) to the include path in php.ini. Then I added the ZF bin folder (C:\xampp\php\ZendFramework-1.10.4\bin) to my Path system variable. To test that everything is configured correctly I ran the command "zf show version" from the command line. The result is "Zend Framework Version: 1.9.6". Immediately something appears to be wrong. The file that is downloaded is "ZendFramework-1.10.4.zip" and the reported version is 1.9.6. I have re-downloaded the latest version (1.10.4) and removed old copy. Still the incorrect version number problem persisted. Having done some research there is a bug in the ZF knowledgebase that version 1.10.3 reports a wrong version number. So that may explain the version number problem. Moving forward I tried to run some zf-tool commands and certain commands reports that the action or provider is not valid. Example: C:\xampp\htdocs>zf create project test Creating project at C:/xampp/htdocs/test C:\xampp\htdocs>cd test C:\xampp\htdocs\test>zf create controller Test Creating a controller at C:\xampp\htdocs\test/application/controllers/TestController.php ... Updating project profile 'C:\xampp\htdocs\test/.zfproject.xml' C:\xampp\htdocs\test>zf create action test Test Creating an action named test inside controller at C:\xampp\htdocs\test/application/controllers/TestController.php ... Updating project profile 'C:\xampp\htdocs\test/.zfproject.xml' C:\xampp\htdocs\test>zf enable layout An Error Has Occurred Action 'enable' is not a valid action. ... C:\xampp\htdocs\test>zf create form Test An Error Has Occurred Provider 'form' is not a valid provider. ... Can any one provide insight into these errors and how to correct them?

  • "Programming In Haskell" error in sat function

    - by Matt Ellen
    I'm in chapter 8 of Graham Hutton's Programming in Haskell and I'm copying the code and testing it in GHC. See the slides here: http://www.cis.syr.edu/~sueo/cis352/chapter8.pdf in particular slide 15 The relevant code I've copied so far is: type Parser a = String -> [(a, String)] pih_return :: a -> Parser a pih_return v = \inp -> [(v, inp)] failure :: Parser a failure = \inp -> [] item :: Parser Char item = \inp -> case inp of [] -> [] (x:xs) -> [(x,xs)] parse :: Parser a -> String -> [(a, String)] parse p inp = p inp sat :: (Char -> Bool) -> Parser Char sat p = do x <- item if p x then pih_return x else failure I have changed the name of the return function from the book to pih_return so that it doesn't clash with the Prelude return function. The errors are in the last function sat. I have copied this directly from the book. As you can probably see p is a function from Char to Bool (e.g. isDigit) and x is of type [(Char, String)], so that's the first error. Then pih_return takes a value v and returns [(v, inp)] where inp is a String. This causes an error in sat because the v being passed is x which is not a Char. I have come up with this solution, by explicitly including inp into sat sat :: (Char -> Bool) -> Parser Char sat p inp = do x <- item inp if p (fst x) then pih_return (fst x) inp else failure inp Is this the best way to solve the issue?

  • pushViewController Not Displaying UIView/Nib with tabbar and nav bar

    - by james
    I'm relatively new to objective c but not programming and am stuck with my iphone app. I created a nav based app with both a navbar and a tab bar controller. I set the tab bar as the root controller. I'm able to switch between each tab without any issues to various UIViews and UITableViews. My issue is that in one of my UITableViews that I call from the TabBarController, didSelectRowAtIndexPath function is suppose to display a new UIView. The below code does not give any errors and runs fine but does not show the new Nib. if(newViewController == nil) { NSLog(@"yes nil"); BookViewController *aNewViewController = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:nil]; self.newViewController = aNewViewController; [aNewViewController release]; } BookAppDelegate *delegate = (BookAppDelegate *)[[UIApplication sharedApplication] delegate]; [delegate.appNavBar pushViewController:newViewController animated:YES]; Now when I do the below, it works fine but it gets rid of the nav and tab which I'm assuming because its a modal call instead of pushing the view controller. BookViewController *screen = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:[NSBundle mainBundle]]; screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:screen animated:YES]; [screen release]; Any ideas why I can't get the View Controller to push correctly? In my application delegate file, I declared an AppNavBarController object (inherit from UINavigationController) called appNavBar. Any help would be appreciated!

  • batch file to merge .js files from subfolders into one combined file

    - by Andrew Johns
    I'm struggling to get this to work. Plenty of examples on the web, but they all do something just slightly different to what I'm aiming to do, and every time I think I can solve it, I get hit by an error that means nothing to me. After giving up on the JSLint.VS plugin, I'm attempting to create a batch file that I can call from a Visual Studio build event, or perhaps from cruise control, which will generate JSLint warnings for a project. The final goal is to get a combined js file that I can pass to jslint, using: cscript jslint.js < tmp.js which would validate that my scripts are ready to be combined into one file for use in a js minifier, or output a bunch of errors using standard output. but the js files that would make up tmp.js are likely to be in multiple subfolders in the project, e.g: D:\_projects\trunk\web\projectname\js\somefile.debug.js D:\_projects\trunk\web\projectname\js\jquery\plugins\jquery.plugin.js The ideal solution would be to be able to call a batch file along the lines of: jslint.bat %ProjectPath% and this would then combine all the js files within the project into one temp js file. This way I would have flexibility in which project was being passed to the batch file. I've been trying to make this work with copy, xcopy, type, and echo, and using a for do loop, with dir /s etc, to make it do what I want, but whatever I try I get an error.

  • Parsing some particular statements with antlr3 in C target

    - by JCD
    Hello all! I have some questions about antlr3 with tree grammar in C target. I have almost done my interpretor (functions, variables, boolean and math expressions ok) and i have kept the most difficult statements for the end (like if, switch, etc.) 1) I would like interpreting a simple loop statement: repeat: ^(REPEAT DIGIT stmt); I've seen many examples but nothing about the tree walker (only a topic here with the macros MARK() / REWIND(m) + @init / @after but not working (i've antlr errors: "unexpected node at offset 0")). How can i interpret this statement in C? 2) Same question with a simple if statement: if: ^(IF condition stmt elseifstmt* elsestmt?); The problem is to skip the statement if the condition is false and test the other elseif/else statements. 3) I have some statements which can stop the script (like "break" or "exit"). How can i interrupt the tree walker and skip the following tokens? 4) When a lexer or parser error is detected, antlr returns an error. But i would like to make my homemade error messages. How can i have the line number where parser crashed? Ask me if you want more details. Thanks you very much (and i apologize for my poor english)
