Accept All Cookies via HttpClient

- by Vinay

So this is currently how my app is set up: 1.) Login Activity. 2.) Once logged in, other activities may be fired up that use PHP scripts that require the cookies sent from logging in. I am using one HttpClient across my app to ensure that the same cookies are used, but my problem is that I am getting 2 of the 3 cookies rejected. I do not care about the validity of the cookies, but I do need them to be accepted. I tried setting the CookiePolicy, but that hasn't worked either. This is what logcat is saying: 11-26 10:33:57.613: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0] [name: cookie_user_id][value: 1][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" 11-26 10:33:57.593: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0][name: cookie_session_id][value: 1985208971][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" I am sure that my actual code is correct (my app still logs in correctly, just doesn't accept the aforementioned cookies), but here it is anyway: HttpGet httpget = new HttpGet(//MY URL); HttpResponse response; response = Main.httpclient.execute(httpget); HttpEntity entity = response.getEntity(); InputStream in = entity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder sb = new StringBuilder(); From here I use the StringBuilder to simply get the String of the response. Nothing fancy. I understand that the reason my cookies are being rejected is because of an "Illegal path attribute" (I am running a script at /mobile-api/login.php whereas the cookie will return with a path of just "/" for trackallthethings), but I would like to accept the cookies anyhow. Is there a way to do this?

Preventing ActiveRecord save() on an instance

- by Craig Walker

I have an ActiveRecord model object Foo; it represents a standard database row. I want to be able to display modified versions of instances of this object. I'd like to reuse the class itself, as it already has all the hooks & aspects I'll need. (For example: I already have a view that displays the appropriate attributes). Basically I want to clone the model instance, modify some of its properties, and feed it back to the caller (view, test, etc). I do not want these attribute modifications getting back into the database. However, I do want to include the id attribute in the cloned version, as it makes dealing with the route-helpers much easier. Thus, I plan on calling ActiveRecord::Base.clone(), manually setting the ID of the cloned instance, and then making the appropriate attribute changes to the new instance. This has me worried though; one save() on the modified instance and my original data will get clobbered. So, I'm looking to lock down the new instance so that it won't hurt anything else. I'm already planning on calling freeze() (on the understanding that this prevents further modification to the object, though the documentation isn't terribly clear). However, I don't see any obvious way to prevent a save(). What would be the best approach to achieving this?

Accessing the value of an input element with XPath in an XSLT

- by asymmetric

Hi! I'm developing a web app that has a button that triggers an XSLT transformation of the document DOM, with a stylesheet fetched via AJAX. Here's a portion of the HTML: <html> <head> <title>Static Javascript-based XMR Form Creator</title> </head> <body> <h1 id="title">Static Javascript-based XMR Form Creator</h1> <div class="opt_block" id="main_opts"> Form name <input type="text" id="form_name" /> Form cols <input type="text" id="form_cols" size="3" maxlength="3" /> </div> <button id="generate">Generate source</button> <textarea rows="20" cols="50" id="xmr_source" ></textarea> </body> Inside the stylesheet, I want to access the value attribute of the first input field, the one with id form_name. The XSLT looks like this: <xsl:template match="/html/body/div[@id = 'main_opts']" > <form> <xsl:attribute name="fname"> <xsl:value-of select="input[@id = 'form_name']/@value" /> </xsl:attribute> </form> </xsl:template> The problem is that the XPath that should do the work: <xsl:value-of select="input[@id = 'form_name']/@value" /> returns nothing. Can anyone help?

Is there a JavaScript event that fires when a tab index switch is triggered? (TABINDEX does not work for inputs in IFRAME)

- by treeface

My specific use case is that I have a WYSIWYG editor which is basically an editable iframe. To the user, however, it looks like a standard-issue textarea. My problem is that I have inputs that sit before and after this editor in the (perceived) tab index and I'd like the user to be able to press tab (or the equivalent on his platform of choice) to get to the WYSIWYG editor when he's in the previous element and shift-tab to get to it when he's in the latter element. I know this can be faked using the key events and checking whether or not the tab key was pressed, but I'm curious if there's a better way. UPDATE. treeface clarified the actual problem in the comments. PROBLEM: In normal case, you can use "TABINDEX" attribute of the <input> element to control that, when tabbing out of "Subject" input field (in an email form), the focus lands on "Body" input field in the e-mail. This is done simply by assigning correctly ordered values to "TABINDEX" attribute of both input fields. The problem is that TABINDEX attribute only orders elements within the same frame. So, if "Body" input field is actually in an internal IFRAME, you can't tab out of "Subject" in the parent frame straight into "Body" in the IFRAME using TABINDEX order.

MEF GetExports<T, TMetaDataView> returning nothing with AllowMultiple = True

- by sohum

I don't understand MEF very well, so hopefully this is a simple fix of how I think it works. I'm trying to use MEF to get some information about a class and how it should be used. I'm using the Metadata options to try to achieve this. My interfaces and attribute looks like this: public interface IMyInterface { } public interface IMyInterfaceInfo { Type SomeProperty1 { get; } double SomeProperty2 { get; } string SomeProperty3 { get; } } [MetadataAttribute] [AttributeUsage(AttributeTargets.Class, AllowMultiple = true)] public class ExportMyInterfaceAttribute : ExportAttribute, IMyInterfaceInfo { public ExportMyInterfaceAttribute(Type someProperty1, double someProperty2, string someProperty3) : base(typeof(IMyInterface)) { SomeProperty1 = someProperty1; SomeProperty2 = someProperty2; SomeProperty3 = someProperty3; } public Type SomeProperty1 { get; set; } public double SomeProperty2 { get; set; } public string SomeProperty3 { get; set; } } The class that is decorated with the attribute looks like this: [ExportMyInterface(typeof(string), 0.1, "whoo data!")] [ExportMyInterface(typeof(int), 0.4, "asdfasdf!!")] public class DecoratedClass : IMyInterface { } The method that is trying to use the import looks like this: private void SomeFunction() { // CompositionContainer is an instance of CompositionContainer var myExports = CompositionContainer.GetExports<IMyInterface, IMyInterfaceInfo>(); } In my case myExports is always empty. In my CompositionContainer, I have a Part in my catalog that has two ExportDefinitions, both with the following ContractName: "MyNamespace.IMyInterface". The Metadata is also loaded correctly per my exports. If I remove the AllowMultiple setter and only include one exported attribute, the myExports variable now has the single export with its loaded metadata. What am I doing wrong?

Aligning messageformat on printing a JTable.

- by DanielFH

I'm using this for the moment to print out my table, and it works. But I'm not really happy with the layout of the messageformatting, I would like to have both pagenumber and date in the footer, and date format aligned to the left side of the table, and page to the right. How can I do that? Been reading some stuff about overriding the PrintTable method, but seems to get pretty complex from what I've read. Hope you can help me with this issue, thank you. :) import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.OrientationRequested; import javax.swing.JTable; import dk.beesys.rims.ui.WindowInventory; public class Print { private static Print INSTANCE; public static Print getInstance() { if (INSTANCE == null) { INSTANCE = new Print(); } return INSTANCE; } private Print(){ } public void printList(java.awt.event.ActionEvent ignore) { String strDate = MessageFormat.format("{0,date,short} {0,time,short}", new Date()); MessageFormat header = new MessageFormat("- {0} -"); MessageFormat footer = new MessageFormat("Printed: " + strDate); PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(OrientationRequested.LANDSCAPE); try { WindowInventory.getInstance().getTable().print(JTable.PrintMode.FIT_WIDTH, header, footer, true, aset, true); } catch (java.awt.print.PrinterException e) { System.err.format("Cannot print %s%n", e.getMessage()); } }

How do I stop Chrome from yellowing my site's input boxes?

- by davebug

Among other text and visual aids on a form submission, post-validation, I'm coloring my input boxes red to signify the interactive area needing attention. On Chrome (and for Google Toolbar users) the auto-fill feature re-colors my input forms yellow. Here's the complex issue: I want auto-complete allowed on my forms, as it speeds users logging in. I am going to check into the ability to turn the autocomplete attribute to off if/when there's an error triggered, but it is a complex bit of coding to programmatically turn off the auto-complete for the single effected input on a page. This, to put it simply, would be a major headache. So to try to avoid that issue, is there any simpler method of stopping Chrome from re-coloring the input boxes? [edit] I tried the !important suggestion below and it had no effect. I have not yet checked Google Toolbar to see if the !important attribute woudl work for that. As far as I can tell, there isn't any means other than using the autocomplete attribute (which does appear to work).

Why does this ActionFilterAttribute not import data to the ViewModel?

- by Tomas Lycken

I have the following attribute public class ImportStatusAttribute : ActionFilterAttribute { public override void OnActionExecuted(ActionExecutedContext filterContext) { var model = (IHasStatus)filterContext.Controller.ViewData.Model; model.Status = (StatusMessageViewModel)filterContext.Controller.TempData["status"]; filterContext.Controller.ViewData.Model = model; } } which I test with the following test method (the first of several I'll write when this one passes...) [TestMethod] public void OnActionExecuted_ImportsStatusFromTempDataToModel() { // Arrange Expect(new { Status = new StatusMessageViewModel() { Subject = "The test", Predicate = "has been tested" }, Key = "status" }); var filterContext = new Mock<ActionExecutedContext>(); var model = new Mock<IHasStatus>(); var tempData = new TempDataDictionary(); var viewData = new ViewDataDictionary(model.Object); var controller = new FakeController() { ViewData = viewData, TempData = tempData }; tempData.Add(expected.Key, expected.Status); filterContext.Setup(c => c.Controller).Returns(controller); var attribute = new ImportStatusAttribute(); // Act attribute.OnActionExecuted(filterContext.Object); // Assert Assert.IsNotNull(model.Object.Status, "The status was not exported"); Assert.AreEqual(model.Object.Status.ToString(), ((StatusMessageViewModel)expected.Status).ToString(), "The status was not the expected"); } (Expect() is a method that saves some expectations in the expected object...) When I run the test, it fails on the first assertion, and I can't get my head around why. Debugging, I can see that model is populated correctly, and that (StatusMessageViewModel)filterContext.Controller.TempData["status"] has the correct data. But after model.Status = (StatusMessageViewModel)filterContext.Controller.TempData["status"]; model.Status is still null in my watch window. Why can't I do this?

SSE (SIMD extensions) support in gcc

- by goldenmean

Hi, I see a code as below: include "stdio.h" #define VECTOR_SIZE 4 typedef float v4sf __attribute__ ((vector_size(sizeof(float)*VECTOR_SIZE))); // vector of four single floats typedef union f4vector { v4sf v; float f[VECTOR_SIZE]; } f4vector; void print_vector (f4vector *v) { printf("%f,%f,%f,%f\n", v->f[0], v->f[1], v->f[2], v->f[3]); } int main() { union f4vector a, b, c; a.v = (v4sf){1.2, 2.3, 3.4, 4.5}; b.v = (v4sf){5., 6., 7., 8.}; c.v = a.v + b.v; print_vector(&a); print_vector(&b); print_vector(&c); } This code builds fine and works expectedly using gcc (it's inbuild SSE / MMX extensions and vector data types. this code is doing a SIMD vector addition using 4 single floats. I want to understand in detail what does each keyword/function call on this typedef line means and does: typedef float v4sf __attribute__ ((vector_size(sizeof(float)*VECTOR_SIZE))); What is the vector_size() function return; What is the __attribute__ keyword for Here is the float data type being type defined to vfsf type? I understand the rest part. thanks, -AD

Why are we getting a WCF "Framing error" on some machines but not others

- by Ian Ringrose

We have just found we are getting “framing errors” (as reported by the WCF logs) when running our system on some customer test machine. It all works ok on our development machines. We have an abstract base class, with KnownType attributes for all its sub classes. One of it’s subclass is missing it’s DataContract attribute. However it all worked on our test machine! On the customers test machine, we got “framing error” showing up the WCF logs, this is not the error message I have seen in the past when missing a DataContract attribute, or a KnownType attribute. I wish to get to the bottom of this, as we can no longer have confidence in our ability to test the system before giving it to the customer until we can make our machines behave the some as the customer’s machines. Code that try to show what I am talking about, (not the real code) [DataContract()] [KnownType(typeof(SubClass1))] [KnownType(typeof(SubClass2))] // other subclasses with data members public abstract class Base { [DataMember] public int LotsMoreItemsThenThisInRealLife; } /// <summary> /// This works on some machines (not not others) when passed to Contract::DoIt, /// note the missing [DataContract()] /// </summary> public class SubClass1 : Base { // has no data members } /// <summary> /// This works in all cases when passed to Contract::DoIt /// </summary> [DataContract()] public class SubClass2 : Base { // has no data members } public interface IContract { void DoIt(Base[] items); } public static class MyProgram { public static IContract ConntectToServerOverWCF() { // lots of code ... return null; } public static void Startup() { IContract server = ConntectToServerOverWCF(); // this works all of the time server.DoIt(new Base[]{new SubClass2(){LotsMoreItemsThenThisInRealLife=2}}); // this works "in develperment" e.g. on our machines, but not on the customer's test machines! server.DoIt(new Base[] { new SubClass1() { LotsMoreItemsThenThisInRealLife = 2 } }); } }

How do I do a count on that meet a specific condition, dependent on several has_many relationships i

- by Angela

I have a Model Campaign. A Campaign has many Events. Each Event has an attribute :days. A Campaign also has_many Contacts. Each Contact as a :date_entered attribute. The from_today(contact,event) method returns a number, which is the number of days from the contact's :date_entered till today minus the event's :days. In other words, a positive number shows the number of days from today till the :days of the event is elapsed. If it is negative, if means that the number of days that has elapsed since the :date_entered is greater than the :days attribute of an event. In other words, the event is overdue. What I would like to be able to do is do campaign.overdue and this would result in a total number of contacts that have an overdue event. It shouldn't count multiple events for a single contact, just one contact. How do I do that? It seems like I would need to cycle through all the events for every contact and keep a counter but I'm assuming that there is a better way.

Get category count for a category where only the child categories have products

- by Matthew

I'm having problems getting a count for a category collection that will include products in any of that categories children. However I don't want just a full count I want to filter that count by a product collection (so only include products in the count that appear in the product collection)... Any suggestions? Code to get a filtered product collection (filtered by a multiselect attribute) /** @var $attribute Mage_Eav_Model_Entity_Attribute */ $valuesCollection = Mage::getResourceModel('eav/entity_attribute_option_collection') ->setAttributeFilter($attribute->getId()) ->addFieldToFilter('value', array ('like' => $make)) ->addFieldToSelect('option_id') ->setStoreFilter(0, false); $set = array(); foreach($valuesCollection as $option){ $set[] = $option->getData('option_id'); } $_productCollection = Mage::getResourceModel('catalog/product_collection') ->addAttributeToFilter('sparex_makemodel', array('in' => $set ) ) ->addAttributeToSelect('*'); I'm getting the child categories for a given category like thus.. $childCats = Mage::getModel('catalog/category')->load(2)->getChildrenCategories(); Now none of these categories have products assigned to them, however their children (or children of children) do. I want to produce a count for these categories that includes the child categories but only where the products are in my filtered collection.

When do Symfony's user attributes get written to session?

- by Rob Wilkerson

I have a Symfony app that populates the "widgets" of a portal application and I'm noticing something (that seems) odd. The portal app has iframes that make calls to the Symfony app. On each of those calls, a random user key is passed on the query string. The Symfony app stores that key its session using myUser->setAttribute(). If the incoming value is different from what it has in session, it overwrites the session value. In pseudo-code (and applying a synchronous nature for clarity even though it may not exist): # Widget request arrives with ?foo=bar if the user attribute 'foo' does not equal 'bar' overwrite the user attribute 'foo' with 'bar' end What I'm noticing is that, on a portal page with multiple widgets (read: multiple requests coming in more or less simultaneously) where the value needs to be overwritten, each request is trying to overwrite. Is this a timing problem? When I look at the log prints, I'd expect the first request that arrives to overwrite and subsequent requests to see that the user attribute they received matches what was just put into cache by the initial request. In this scenario, it could be that subsequent requests begin (and are checked) even before the first one--the one that should overwrite the cached value--has completely finished. Are session values not really available to subsequent requests until one request has completed entirely or could there be something else that I'm missing? Thanks.

How to replace auto-implemented c# get body at runtime or compile time?

- by qstarin

I've been trying to figure this out all night, but I guess my knowledge of the .Net Framework just isn't that deep and the problem doesn't exactly Google well, but if I can get a nod in the right direction I'm sure I can implement it, one way or another. I'd like to be able to declare a property decorated with a custom attribute as such: public MyClass { [ReplaceWithExpressionFrom(typeof(SomeOtherClass))] public virtual bool MyProperty { get; } } public SomeOtherClass : IExpressionHolder<MyClass, bool> { ... } public interface IExpressionHolder<TArg, TResult> { Expression<Func<TArg, TResult>> Expression { get; } } And then somehow - this is the part I'm having trouble figuring - replace the automatically generated implementation of that getter with a piece of custom code, something like: Type expressionHolderType = LookupAttributeCtorArgTypeInDeclarationOfPropertyWereReplacing(); return ReplaceWithExpressionFromAttribute.GetCompiledExpressionFrom(expressionHolderType)(this); The main thing I'm not sure how to do is replace the automatic implementation of the get. The first thing that came to mind was PostSharp, but that's a more complicated dependency than I care for. I'd much prefer a way to code it without using post-processing attached to the build (I think that's the jist of how PostSharp sinks its hooks in anyway). The other part of this I'm not so sure about is how to retrieve the type parameter passed to the particular instantiation of the ReplaceWithExpressionFrom attribute (where it decorates the property whose body I want to replace; in other words, how do I get typeof(SomeOtherClass) where I'm coding the get body replacement). I plan to cache compiled expressions from concrete instances of IExpressionHolder, as I don't want to do that every time the property gets retrieved. I figure this has just got to be possible. At the very least I figure I should be able to search an assembly for any method decorated with the attribute and somehow proxy the class or just replace the IL or .. something? And I'd like to make the integration as smooth as possible, so if this can be done without explicitly calling a registration or initialization method somewhere that'd be super great. Thanks!

Fortran pointer as an argument to interface procedure

- by icarusthecow

Im trying to use interfaces to call different subroutines with different types, however, it doesnt seem to work when i use the pointer attribute. for example, take this sample code MODULE ptr_types TYPE, abstract :: parent INTEGER :: q END TYPE TYPE, extends(parent) :: child INTEGER :: m END TYPE INTERFACE ptr_interface MODULE PROCEDURE do_something END INTERFACE CONTAINS SUBROUTINE do_something(atype) CLASS(parent), POINTER :: atype ! code determines that this allocation is correct from input ALLOCATE(child::atype) WRITE (*,*) atype%q END SUBROUTINE END MODULE PROGRAM testpass USE ptr_types CLASS(child), POINTER :: ctype CALL ptr_interface(ctype) END PROGRAM This gives error Error: There is no specific subroutine for the generic 'ptr_interface' at (1) however if i remove the pointer attribute in the subroutine it compiles fine. Now, normally this wouldnt be a problem, but for my use case i need to be able to treat that argument as a pointer, mainly so i can allocate it if necessary. Any suggestions? Mind you I'm new to fortran so I may have missed something edit: forgot to put the allocation in the parents subroutine, the initial input is unallocated EDIT 2 this is my second attempt, with caller side casting MODULE ptr_types TYPE, abstract :: parent INTEGER :: q END TYPE TYPE, extends(parent) :: child INTEGER :: m END TYPE TYPE, extends(parent) :: second INTEGER :: meow END TYPE CONTAINS SUBROUTINE do_something(this, type_num) CLASS(parent), POINTER :: this INTEGER type_num IF (type_num == 0) THEN ALLOCATE (child::this) ELSE IF (type_num == 1) THEN ALLOCATE (second::this) ENDIF END SUBROUTINE END MODULE PROGRAM testpass USE ptr_types CLASS(child), POINTER :: ctype SELECT TYPE(ctype) CLASS is (parent) CALL do_something(ctype, 0) END SELECT WRITE (*,*) ctype%q END PROGRAM however this still fails. in the select statement it complains that parent must extend child. Im sure this is due to restrictions when dealing with the pointer attribute, for type safety, however, im looking for a way to convert a pointer into its parent type for generic allocation. Rather than have to write separate allocation functions for every type and hope they dont collide in an interface or something. hopefully this example will illustrate a little more clearly what im trying to achieve, if you know a better way let me know

MVC Validator.TryValidateObject does not validate custom atrribute, validateAllProperties = true

- by nealsu

When calling Validator.TryValidateObject with validateAllProperties = true my custom validation attribute does not get triggered. The ValidationResult does not contain an entry for my erroneous property value. Below is the model, attribute and code used to test this. //Model public class Model { [AmountGreaterThanZero] public int? Amount { get; set; } } //Attribute public sealed class AmountGreaterThanZero: ValidationAttribute { private const string errorMessage = "Amount should be greater than zero."; public AmountGreaterThanZero() : base(errorMessage) { } public override string FormatErrorMessage(string name) { return errorMessage; } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { if (value != null) { if ((int)value <= 0) { var message = FormatErrorMessage(validationContext.DisplayName); return new ValidationResult(message); } } return null; } } //Validation Code var container = new Container(); container.ModelList = new List<Model>() { new Model() { Amount = -5 } }; var validationContext = new ValidationContext(container, null, null); var validationResults = new List<ValidationResult>(); var modelIsValid = Validator.TryValidateObject(container, validationContext, validationResults, true); Note: That the validation works fine and ValidationResult returns with correct error message if I use the TryValidateProperty method.

Why is Attributes.IsDefined() missing overloads?

- by Hans Passant

Inspired by an SO question. The Attribute class has several overloads for the IsDefined() method. Covered are attributes applied to Assembly, Module, MemberInfo, ParameterInfo. The MemberInfo overload covers PropertyInfo, FieldInfo, EventInfo, MethodInfo, ConstructorInfo. That takes care of most of the AttributeTargets. Except for one biggy: there is no overload for Attribute.IsDefined(Type, Type) so that you could check if an attribute is defined on a class. Or a struct, delegate or enum for that matter. Not that this is a real problem, Type.GetCustomAttributes() can fix that. But all of the BlahInfo types have this too. I wonder at the lack of symmetry. I can't put a finger on why this would be problem for Type. Guessing at an inheritance problem doesn't explain it to me. Having ValueType in the mix might be a lead, still doesn't make sense. I don't buy "they forgot", they never do. Why is this overload missing?

Hi, I have a topic configured correctly like this, in jboss 5.1: <mbean code="org.jboss.jms.server.destination.TopicService" name="jboss.messaging.destination:service=Topic,name=GreetingsTopic" xmbean-dd="xmdesc/Topic-xmbean.xml"> <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer </depends> <depends>jboss.messaging:service=PostOffice</depends> </mbean> I can see the topic being started in JBoss logs: 23:08:40,990 INFO [TopicService] Topic[/topic/GreetingsTopic] started, fullSize=200000, pageSize=2000, downCacheSize=2000 And I have this MDB: @MessageDriven(activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jmx.Topic"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/GreetingsTopic") }) public class GreetingsClientWebMDB implements MessageListener { ... ... } When I deploy the MDB, I'm getting a strange error: 3:09:30,781 ERROR [JmsActivation] Unable to reconnect org.jboss.resource.adapter.jms.inflow.JmsActivationSpec@1a1d638(ra=org.jboss.resource.adapter.jms.JmsResourceAdapter@1da5b5b destination=topic/GreetingsTopic destinationType=javax.jmx.Topic tx=true durable=false reconnect=10 provider=java:/DefaultJMSProvider user=null maxMessages=1 minSession=1 maxSession=15 keepAlive=60000 useDLQ=true DLQHandler=org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler DLQJndiName=queue/DLQ DLQUser=null DLQMaxResent=5) java.lang.ClassCastException: Object at 'topic/GreetingsTopic' in context {java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory, java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces:org.jboss.naming:org.jnp.interfaces} is not an instance of [class=javax.jms.Queue classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml} interfaces={interface=javax.jms.Destination classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml}}] object class is [class=org.jboss.jms.destination.JBossTopic classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml} interfaces={interface=javax.jms.Topic classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml}}] at org.jboss.util.naming.Util.checkObject(Util.java:338) at org.jboss.util.naming.Util.lookup(Util.java:223) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setupDestination(JmsActivation.java:464) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setup(JmsActivation.java:352) at org.jboss.resource.adapter.jms.inflow.JmsActivation.handleFailure(JmsActivation.java:292) at org.jboss.resource.adapter.jms.inflow.JmsActivation$SetupActivation.run(JmsActivation.java:733) at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:205) at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:260) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) I also try to use a deployment descriptor instead of annotations but with the same result. I really can't see the problem :(

How to override C# DateTime serialization with class auto-generated from wsdl?

- by Calvin Fisher

I have a WSDL that the consumer of my web service expects will be adhered to strictly. I converted it into an interface with wsdl.exe and had my web service implement it. Except for this problem, I have been generally pleased with the results. A simple GetCurrentTime method will have the following response class generated from the WSDL in the interface definition: [System.CodeDobmCompiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(Namespace="[Client Namespace]")] public partial class GetCurrentTimeResponse { private System.DateTime timeStampField; [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified] public System.DateTime TimeStamp{ // [accesses timeStampField] } } When I put the response data into the automatically generated response class, it gets serialized into an appropriate XML response. (Most of the web methods have much more complicated return types with multiple levels of arrays.) The problem is that the default serialization of DateTime objects violates one of the requirements in the WSDL: ... <xsd:simpleType name="SearchTimeStamp"> <xsd:restriction base="xsd:dateTime"> <xsd:pattern value="[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}(.[0-9]{1,7})?Z"> </xsd:restriction> </xsd:simpleType> ... Note the last part of the pattern where subseconds must be either 1 or 7 characters if they are included. The client seems to be rejecting the response because it does not match that requirement. The main issue is that when .NET serializes a DateTime object, it omits all trailing zeroes, meaning the resulting subsecond value varies in length. (e.g., "12:34:56.700" gets serialized as "<TimeStamp>12:34:56:7</TimeStamp>" by default). We use millisecond precision, so I need all timestamps to format with 7 subsecond digits in order to be compliant with the WSDL. It would be easy if I could specify a format string, but I'm not sure how to control the string that the DateTime object uses to serialize to XML, or to otherwise override the serialization behavior. How do I do this? Keeping in mind the following... I would like to modify the generated code as little as possible... preferably not at all if the change can be made through a partial class or inherited class. Using an inherited class for the return type of the web method will cause the web service to no longer implement the auto-generated interface. The TimeStamp type occurs in other, more complex response types. So, manually overriding the entire serialization process may be prohibitively time-consuming.

IdHttp Post Method Delphi 2010

- by Dusten S

Like others before me, I'm having troubles using the IdHttp(Indy 10.5.5) component in Delphi 2010. The code works fine in Delphi 7: var XMLString : AnsiString; lService : AnsiString; ResponseStream: TMemoryStream; InputStringList : TStringList; begin ResponseStream := TMemoryStream.Create; InputStringList := TStringList.Create; XMLString :='<?xml version="1.0" encoding="ISO-8859-1"?> '+ '<!DOCTYPE pnet_imessage_send PUBLIC "-//PeopleNet//pnet_imessage_send" "http://open.peoplenetonline.com/dtd/pnet_imessage_send.dtd"> '+ '<pnet_imessage_send> '+ ' <cid>username</cid> '+ ' <pw>password</pw> '+ ' <vehicle_number>tr01</vehicle_number> '+ ' <deliver>now</deliver> '+ ' <action> '+ ' <action_type>reply_with_freeform</action_type> '+ ' <urgent_reply>yes</urgent_reply> '+ ' </action> '+ ' <freeform_message>Test Message Version 2</freeform_message> '+ '</pnet_imessage_send> '; lService := 'imessage_send'; InputStringList.Values['service'] := lService; InputStringList.Values['xml'] := XMLString; try IdHttp1.Request.Accept := '*/*'; IdHttp1.Request.ContentType := 'text/XML'; IdHTTP1.Post('http://open.peoplenetonline.com/scripts/open.dll', InputStringList, ResponseStream); ... finally ResponseStream.Free; InputStringList.Free; end; The only differences so far between this and the D7 code is that I've changed the String types to AnsiString, and added the HTTP Request properties. The response I get back from the server is 'XML failed to parse. Whitespace expected at Line:1 Position: 19', I'm assuming the XML got garbled up somewhere in the process, but I can't figure our where I'm going wrong. Any ideas?

GZip compression with WCF hosted on IIS7

- by joniba

So I'm going to add my query to the small ocean of questions on the subject. I'm trying to enable GZip compression on large soap responses from a WCF service. So far, I've followed instructions here and in a variety of other places to enable dynamic compression on IIS. Here's my dynamicTypes section from the applicationHost.config: <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> <add mimeType="application/xop+xml" enabled="true" /> <add mimeType="application/soap+xml" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> And also: <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> Though I'm not so clear on why that's needed. Threw some extra mime-types in there just in case. I've implemented IClientMessageInspector to add Accept-Encoding: gzip, deflate to my client's HttpRequests. Here's an example of a request-header taken from fiddler: POST http://[omitted]/TestMtomService/TextService.svc HTTP/1.1 Content-Type: application/soap+xml; charset=utf-8 Accept-Encoding: gzip, deflate Host: [omitted] Content-Length: 542 Expect: 100-continue Now, this doesn't work. There's simply no compression happening, no matter what the size of the message (tried up to 1.5Mb). I've looked at this post, but have not run into an exception as he describes, so I haven't tried the CodeProject implementation that he proposes. Also I've seen a lot of other implementations that are supposed to get this to work, but cannot make sense of them (e.g., msdn's GZip encoder). Why would I need to implement the encoder, or the code-project solution? Shouldn't IIS take care of the compression? So what else do I need to do to get this to work? Joni

Error during maven/ant build: "[java] Timestamp response not valid"

Can/should one disable namespace validation in Axis2 clients using ADB databinding?

- by RJCantrell

I have an document/literal Axis 1 service which I'm consuming with an Axis 2 client (ADB databinding, generated from WSDL2Java). It receives a valid XML response, but in parsing that XML, I get the error "Unexpected Subelement" for any type which doesn't have a namespace defined in the response. I can resolve the error by manually changing the (auto-generated by Axis2) type-validation line to only check the type name and not the namespace as well, but is there a non-manual way to skip this? This service is consumed properly by other Axis 1 clients. Here's the response, with bits in ALL CAPS having been anonymized. Some types have namespaces, some have empty-string namespaces, and some have none at all. Can I control this via the service's WSDL, or in Axis2's WSDL2Java handling of the WSDL? Is there a fundamental mismatch between Axis 1 and Axis2? The response below looks correct, except perhaps for where that type (anonymized as TWO below) is nested within itself. <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <SERVICENAMEResponse xmlns="http://service.PROJECT.COMPANY.com"> <SERVICENAMEReturn xmlns=""> <ONE></ONE> <TWO><TWO> <THREE>2</THREE> <FOUR>-10</FOUR> <FIVE>6</FIVE> <SIX>1</SIX> </TWO></TWO> <fileName></fileName> </SERVICENAMEReturn></SERVICENAMEResponse> </soapenv:Body></soapenv:Envelope> I did not have to modify the validation of the "SERVICENAMEResponse" object because it has the correct namespace specified, but I have to so for all its subelements. The manual modification that I can make (one per type) to fix this is to change: if (reader.isStartElement() && new javax.xml.namespace.QName("http://dto.PROJECT.COMPANY.com","ONE").equals(reader.getName())){ to: if (reader.isStartElement() && new javax.xml.namespace.QName("ONE").equals(reader.getName())){

PopulateOnDemand does not work on data bound ASP.Net TreeView

- by Shay Friedman

Hi, I have a TreeView that is bound to a XmlDataSource control. I've added some TreeNodeBinding elements to define how I want the XML data to be shown. I have also added PopulateOnDemand=true to these TreeNodeBindings. However, doing so didn't change a thing and the entire XML tree is displayed. Moreover, the TreeNodePopulate event is not fired on node expand as well. Important information: I'm using ASP.NET 4. This is an example that reproduces the problem (very straight forward): <%@ Page Language="C#" AutoEventWireup="true" %> <script type="text/C#" runat="server"> protected void TreeView1_TreeNodePopulate(Object sender, TreeNodeEventArgs e) { // This method is never called... } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:TreeView ID="TreeView1" runat="server" DataSourceID="XmlDataSource1" OnTreeNodePopulate="TreeView1_TreeNodePopulate" ExpandDepth="0"> <DataBindings> <asp:TreeNodeBinding DataMember="#" TextField="#" ValueField="#" PopulateOnDemand="true" /> </DataBindings> </asp:TreeView> <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="Sample.xml" /> </div> </form> </body> </html> The Sample.xml can be any xml file you want, it doesn't really matter. I tried to put a breakpoint within the TreeView1_TreeNodePopulate method and it was never hit. I also tried to: Set a TreeNodeBinding for each possible data member with PopulateOnDemand="true". Via code, go through all tree nodes and set their PopulateOnDemand property to true. Nothing worked. The only way the populate-on-demand thing worked was when I added nodes manually to the nodes instead of binding it to a data source. What am I doing wrong?
