Hello...dunno if this is the right board since i saw there is a JBOSS.NET board as well. I hope it will fit in here. actually i'am using EJB 3.0 and trying to access a simple HelloWorld method from a C# Client. But it seems that the *.wsdl file which is generated by my annotations does'nt work properly. The created ws has some problems in the root elements...in my C# Client he thinks that my HelloWorld method is a class as well as the class himself and expect a object with the methodname as a parameter. strange. Furthermore i have to tell you that i've tried to do the same with glassfish and it works. So i think there might be problems with the generated wsdl or some flag i did'nt set. Even though i dont believe that i'am the first who is trying to connect a c# client with a java-based middleware with jboss... ;) afaik for a .NET environment i need to change the soapBinding to @SOAPBinding(style=Style.DOCUMENT, use=Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED) . I changed the method names to uppercase because i think .net expect this. (glassfish is working with the same SOAPBinding setup) my testing class: | @Stateless | @WebService | @SOAPBinding(style=Style.DOCUMENT, use=Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED) | public class CustomersSessionBean { | public void addCustomer(Customer customer) { | System.out.println("test"); | } | | public Customer loadCustomer() { | System.out.println("test"); | return null; | } | | @WebMethod(operationName="HelloWorld") | @WebResult(name="Hello") | public String HelloWorld(){ | return "Hello World"; | } | } i've created the same class in .NET and let them generate a localhost webservice to compare both *.wsdl files. to watch the following *.wsdl files you need the IE...opera does'nt work with them unfortunatly (ff i dont know) jboss generated wsdl: http://www.dowhilefalse.com/wsdl/jboss.wsdl loc: 46 .NET generated wsdl: http://www.dowhilefalse.com/wsdl/dotnet.wsdl loc: 46 glassfish generated wsdl: http://www.dowhilefalse.com/wsdl/glassfish.wsdl loc: 36 O_O btw to write the wsdl's manually is no option! best thx and greetings from germany D.
