Error while Generating wsdl from wsgen tool

Question

Hi All,
I am trying out wsdl generation with the help of the wsgen tool. I have endorsed jaxb-api.jar and jaxws-api.jar files.
I have a library TestTo which has TestingTo class AS
public class TestingTo implements Serializable{
public String name;
This TestTO library is included in webservice project.
My WebService is as below-
@WebService()
public class IcfInfra {
@WebMethod(operationName = "printTest")
public TestingTo printTest(@WebParam(name = "string") String string)
TestingTo to = new TestingTo();
to.name = string;
System.out.println(string);
return to;
When I run Ant script for Wsgen I get following error -
main: [exec] Note: ap round: 1 [exec] Problem encountered during annotation processing; [exec] see stacktrace below for more information. [exec] java.lang.NullPointerException [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalType(WebServiceVisitor.java:794) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalMethod(WebServiceVisitor.java:642) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.methodsAreLegal(WebServiceVisitor.java:611) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalImplementation(WebServiceVisitor.java:529) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.shouldProcessWebService(WebServiceVisitor.java:332) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.visitClassDeclaration(WebServiceVisitor.java:123) [exec] at com.sun.tools.apt.mirror.declaration.ClassDeclarationImpl.acc ept(ClassDeclarationImpl.java:95) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceAP.bu ildModel(WebServiceAP.java:329) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceAP.pr ocess(WebServiceAP.java:270) [exec] at com.sun.mirror.apt.AnnotationProcessors$CompositeAnnotationPr ocessor.process(AnnotationProcessors.java:60) [exec] at com.sun.tools.apt.comp.Apt.main(Apt.java:454) [exec] at com.sun.tools.apt.main.JavaCompiler.compile(JavaCompiler.java :258) [exec] at com.sun.tools.apt.main.Main.compile(Main.java:1102) [exec] at com.sun.tools.apt.main.Main.compile(Main.java:964) [exec] at com.sun.tools.apt.Main.processing(Main.java:95) [exec] at com.sun.tools.apt.Main.process(Main.java:85) [exec] at com.sun.tools.apt.Main.process(Main.java:67) [exec] at com.sun.tools.ws.wscompile.WsgenTool.buildModel(WsgenTool.jav a:219) [exec] at com.sun.tools.ws.wscompile.WsgenTool.run(WsgenTool.java:123) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAcces sorImpl.java:39) [exec] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMet hodAccessorImpl.java:25) [exec] at java.lang.reflect.Method.invoke(Method.java:597) [exec] at com.sun.tools.ws.Invoker.invoke(Invoker.java:131) [exec] at com.sun.tools.ws.WsGen.main(WsGen.java:52) [exec] error: compilation failed, errors should have been reported [exec] Result: 1
Now I modified my webservice as
@WebService()
@XmlSeeAlso({
TestingTo.class
public class IcfInfra {
@WebMethod(operationName = "printTest")
public TestingTo printTest(@WebParam(name = "string") String string){
TestingTo to = new TestingTo();
to.name = string;
System.out.println(string);
return to;
When I execute ant script i get error as -
main: [exec] Exception in thread "main" java.lang.ArrayStoreException: sun.reflec t.annotation.TypeNotPresentExceptionProxy [exec] at sun.reflect.annotation.AnnotationParser.parseClassArray(Annot ationParser.java:653) [exec] at sun.reflect.annotation.AnnotationParser.parseArray(Annotation Parser.java:460) [exec] at sun.reflect.annotation.AnnotationParser.parseMemberValue(Anno tationParser.java:286) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotation(Annot ationParser.java:222) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotations2(Ann otationParser.java:69) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotations(Anno tationParser.java:52) [exec] at java.lang.Class.initAnnotationsIfNecessary(Class.java:3070) [exec] at java.lang.Class.getAnnotation(Class.java:3029) [exec] at com.sun.tools.ws.wscompile.WsgenOptions.validateEndpointClass (WsgenOptions.java:244) [exec] at com.sun.tools.ws.wscompile.WsgenOptions.validate(WsgenOptions .java:226) [exec] at com.sun.tools.ws.wscompile.WsgenTool.run(WsgenTool.java:122) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAcces sorImpl.java:39) [exec] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMet hodAccessorImpl.java:25) [exec] at java.lang.reflect.Method.invoke(Method.java:597) [exec] at com.sun.tools.ws.Invoker.invoke(Invoker.java:131) [exec] at com.sun.tools.ws.WsGen.main(WsGen.java:52)
Appreciate If someone can let me know what needs to be done in order to sucessfully generate the wsdl.
Thanks, Adish

You are trying to use a custom class as a return type?
The return type needs to be JAX-B compatible
see: http://download.oracle.com/docs/cd/E17802_01/webservices/webservices/docs/2.0/tutorial/doc/JAXWS3.html
You should avoid using user defined complex types as much as possible because they require the clients to be able to process them as well making your webservice less portable and thus defeating the main advantages of webservices.
