I am trying to use an Ice client in an OSGi context. Running the server and a minimal example client in a non-OSGi environment works fine. With the client in an OSGi environment I get the following exception:
com.zeroc.Ice.NoValueFactoryException
reason = "no value factory found and compact format prevents slicing (the sender should use the sliced format instead)"
type = "::MyModule::Knowledge::CMKnowledge"
However, I am not 100% sure, if the OSGi runtime makes a difference here. The Slice file looks like this:
module MyModule{
module Knowledge{
class KnowledgePart{
string value;
}
class FMKnowledge extends KnowledgePart{}
class CMKnowledge extends KnowledgePart{}
interface IKnowledge{
void sendKnowledge(KnowledgePart knowledge);
FMKnowledge getFMKnowledge();
CMKnowledge getCMKnowledge();
}
}
}
What does this exception mean in this context and how can I fix it? I already tried to set ["format:sliced"] instead of the implicitly used compact format.
The error mean that Ice run-time try to load MyModule.Knowledge.CMKnowledge class but it failed to do so. You must ensure that the class loader used by the application can load MyModule.Knowledge.CMKnowledgeclass.

I have a simple problem.
I've created a WCF Data Service 5.6 in visual studio 2013, and in its *.svc.cs file, modified line
public class CustomdataService : DataService< /* TODO: put your data source class name here */ >
to connect my entities
public class CustomdataService : DataService< SchedulerEntities >
But when I want to see the service in browser it gives me following error
Request Error
The server encountered an error processing the request. See server logs for more details.
The entity framework is nothing but a single table...
The actual error can be different. In my case I got the same general error message when starting with AdventureWorks2012 database.
So the actual problem can be seen by appending an attribute to the service class as described at here:
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class WcfDataServiceAW : EntityFrameworkDataService<AdventureWorks2012Entities> { ... }
Hope it helps someone.
PS. My error is:
The exception message is 'The property 'SpatialLocation' on type 'Address' is of type 'Geography' which is not a supported primitive type.'.
It seems that Entity Framework 6 and WCF Data Services 5.6.0 need some provider to work together, read more on Using WCF Data Services 5.6.0 with Entity Framework 6+.
You can download the provider simply by using NuGet Package Console Manager:
Install-Package Microsoft.OData.EntityFrameworkProvider -Pre
Its version is alpha 2, so in future, search for final release. it worked for me however.
Final thing is, instead of using DataService<T>, you need to use EntityFrameworkDataService<T>. T is the name of your entities.
According to this post, you have to change inherited type of CustomdataService.
Replace the base type of your DataService. For EF 5 or below, your data service should inherit from DataService where T is a DbContext or ObjectContext. For EF 6 or greater, your data service should inherit from EntityFrameworkDataService where T is a DbContext. See What’s the difference between DataService and EntityFrameworkDataService below for more details.
go to edmx, in the diagram, remove all the tables until the only one you want is remain,
then should be okay, cannot have all the tables, this is what I found,

Since we upgraded the flex sdk in our application to 4.10 we've been running into Verify Errors while running unit tests that use mockolate.
They seem to occur when mocking an interface where a ByteArray is used in a method signature.
Example interface:
public interface IFileSystemHelper {
function loadFileContents(path:String):ByteArray;
}
Example test class:
public class SomeTest {
[Rule]
public var mockolateRule:MockolateRule = new MockolateRule();
[Mock]
public var fileHelper:IFileSystemHelper;
public function SomeTest() {
}
[Test]
public function testMethod():void {
// ...
}
}
When compiling and running the test with flexmojos 6.0.1 the following error is thrown:
VerifyError: Error #1053: Illegal override of
IFileSystemHelper8F2B5D281827800A824B85B588C6F2A08AE814ED in
mockolate.generated.IFileSystemHelper8F2B5D281827800A824B85B588C6F2A08AE814ED
My initial suspicion was an sdk version problem with playerglobal (or airglobal in our case) so i recompiled mockolate (and flexunit) with sdk 4.10, without any result.
The only thing that seems to work is to remove the ByteArray type from the method signature... but that's not really an option :-) (and this has never been a problem before)
Is there anyone who has had a similar issue?
Thanks
This problem usually occurs when compiling different parts of your application with different versions of the sdk.
I would recommend to have a look at the output of "mvn dependency:tree" as this should output all dependencies (direct and transitive ones). Perhaps this will help you find where the wrong version is comming from.
I've defined an unordered group and it works like I expected. The only thing I would like to change is the error msg, which appears when an element of an unordered group isn't modelled yet. Is there an easy way to solve this? I tried already custom checks, but there I got an unexpected behaviour.
Following my rule for the unordered group and the error msg:
Element:
(name=ConfigurationName) &
(description=Description)? &
(tool=Tool) &
(model=Model) &
(interfaces=Interfaces)? &
(paramaters=Parameters)? &
(paramfile=ParamFile)?
;
rule ruleElement failed predicate: {getUnorderedGroupHelper().canLeave(grammarAccess.getElementAccess().getUnorderedGroup())}?
I want to change this error msg to something like: "The following elements are required in the configuration:...."
Xtext has a service called SyntaxErrorMessageProvider that is used to reword parser error messages. You have to define your messages on the parser level (so there will be no EMF model to use), but it is possible to get the original error message and the context, traverse it and provide your own error message.
To register this, open the «YourLanguage»RuntimeModule class, and add the following method:
public Class<? extends ISyntaxErrorMessageProvider> bindISyntaxErrorMessageProvider() {
return «YourLanguage»SyntaxErrorMessageProvider.class;
}
where «YourLanguage«SyntaxErrorMessageProvider is a class introduced by you, extending the class SyntaxErrorMessageProvider, where you can implement your custom function.
I works Automatic Validation customize,I create
public class MyDslLanguageSyntaxErrorMessageProvider extends SyntaxErrorMessageProvider {
}
And I Register it in the MyDslRuntimeModule:
public Class bindISyntaxErrorMessageProvider() {
return MyDslLanguageSyntaxErrorMessageProvider.class;}
But my problem is which package is used for this customization.I used org.xtext.example.mydsl.validation package for create java class .Also I do this customization with xtend class.I do not find enough source in the internet :(
You can use Java to write this Custom SyntaxErrorMessageProvider class, but to bind this you can bind in Runtime Module class. Also u can use any package to declare this class but declaring this class in same package where u have Runtime class makes sense
I would like to know if the tool "wsdl2java" (Axis2) is able to generate stubs that support getting list of custom ojects.
For instance, if I have a WS that have the following method:
public List<Device> getDevices(){
//...
}
Where Device is a custom class...
This tool can do that?
I changed the return data type of my Web Service to an array because of that:
http://www.ibm.com/developerworks/webservices/library/ws-tip-coding/index.html
And I had to do some changes (some namespaces) to the generated stub (I used ADB)...
I changed that because it was giving me an ADBException: Unexpected subelement ...
I want to retrieve a Map from a using JAX-RS (text/xml)
#GET
public Map<String,String> getMap(){
}
but I am getting the error below:
0000001e FlushResultHa E org.apache.wink.server.internal.handlers.FlushResultHandler handleResponse The system could not find a javax.ws.rs.ext.MessageBodyWriter or a DataSourceProvider class for the java.util.HashMap type and application/x-ms-application mediaType.

The solution I choose is to wrap a Map and use it for the return param.
#XmlRootElement
public class JaxrsMapWrapper {
private Map<String,String> map;
public JaxrsMapWrapper(){
}
public void setMap(Map<String,String> map) {
this.map = map;
}
public Map<String,String> getMap() {
return map;
}
}
and the method signature will go like this
#GET
public JaxrsMapWrapper getMap()
Your problem is that the default serialization strategy (use JAXB) means that you can't serialize that map directly. There are two main ways to deal with this.
Write an XmlAdaptor
There are a number of questions on this on SO but the nicest explanation I've seen so far is on the CXF users mailing list from a few years ago. The one tricky bit (since you don't want an extra wrapper element) is that once you've got yourself a type adaptor, you've got to install it using a package-level annotation (on the right package, which might take some effort to figure out). Those are relatively exotic.
Write a custom MessageBodyWriter
It might well be easier to write your own code to do the serialization. To do this, you implement javax.ws.rs.ext.MessageBodyWriter and tag it with #Provider (assuming that you are using an engine that uses that to manage registration; not all do for complex reasons that don't matter too much here). This will let you produce exactly the document you want from any arbitrary type at a cost of more complexity when writing (but at least you won't be having complex JAXB problems). There are many ways to actually generate XML, with which ones to choose between depending on the data to be serialized
Note that if you were streaming the data out rather than assembling everything in memory, you'd have to implement this interface.
Using CXF 2.4.2, it supports returning Map from the api. I use jackson-jaxrs 1.9.6 for serialization.
#Path("participation")
#Consumes({"application/json"})
#Produces({"application/json"})
public interface SurveyParticipationApi {
#GET
#Path("appParameters")
Map<String,String> getAppParameters();
....
}
With CXF 2.7.x use
WebClient.postCollection(Object collection, Class<T> memberClass, Class<T> responseClass)
,like this in your rest client code.
(Map<String, Region>) client.postCollection(regionCodes, String.class,Map.class);
for other collections use WebClient.postAndGetCollection().
