Reporter: unless you sure which component to use, please use 'ide' and your issue will get reassigned.

Please excuse my incorect component, I put something based on my best guess. I will go to ide from now on .

Anyway using method of elimination I discovered what does always trigger this error: 

Configuration : 
Project A - Java class library - contains interface IA and class CA1 and CA2 and CA3:
public interface IA{

    public boolean accept(CA1 param);
    
}

Project B ( has Project A as dependency ) is a Web project conatining the web service.

then adding folowing code in web service definition triggers the error without any clean message:

    @WebMethod(operationName = "getMyList")
    public List<CA2> getMyList( CA3 owner, IA filter)  {
        throw new UnsupportedOperationException("Not supported yet.");
    }

by removing filter parameter like below wsgen works corect again.

    @WebMethod(operationName = "getMyList")
    public List<CA2> getMyList( CA3 owner )  {
        throw new UnsupportedOperationException("Not supported yet.");
    }


I am aware that wsgem may not suport interfaces as parameters but we are expecting a clean error message pointing to the
cause of error. 

Thanks.

WSGEN really fails with a strange message.
Please, report this to JAX-WS team at https://jax-ws.dev.java.net

Nevertheless, I tried to help user as much as possible and removed unnecessary WSDL generation on project side :
http://hg.netbeans.org/main?cmd=changeset;node=09da9ad75be2

Now, the Build project passes without problems, but the deployment fails with more descriptive message, like :

hello.MyInterface is an interface, and JAXB can't handle interfaces.
        this problem is related to the following location:
                at hello.MyInterface
                at public hello.MyInterface hello.jaxws.GetName.parameter
                at hello.jaxws.GetName
hello.MyInterface does not have a no-arg default constructor.
        this problem is related to the following location:
                at hello.MyInterface
                at public hello.MyInterface hello.jaxws.GetName.parameter
                at hello.jaxws.GetName

Note: I used hello.MyInterface, instead of IA interface.

It looks a bit hard to get observer status on JAX-WS team at https://jax-ws.dev.java.net
until then the same ambiguos error ocurs when one parameter of a web method is a Map<String, String>.
We are expecting to see some meaningful error.

It looks very long time to get observer status on jaxws.
Meanwhile I look on their source and found further clues that may be considered.

I look into the sources for jaxws and the only place where the error I encountered appears is in
file WSGen2.java line 490  (see code snippet) The tool may show some exception (or place stack trace in a log file) but
it seems not to reach Netbeans output.

I think that it is desired to show the error as early as possible.

I reopen to bring this in your attention and consideration.

I hope this helps .  

package com.sun.tools.and.ws;
....

        } catch (Exception ex) {
            if (failonerror) {
                if (ex instanceof BuildException) {
                    throw (BuildException) ex;
                } else {
                    throw new BuildException("Error starting wsgen: ", ex,
                            getLocation());
                }
            } else {
                StringWriter sw = new StringWriter();
                ex.printStackTrace(new PrintWriter(sw));
                getProject().log(sw.toString(), Project.MSG_WARN);
                // continue
            }

I reassigned the issue to JAX-WS team. Netbeans cannot do much about that.
