Sample WebService using XFire

[java_dev]

Hi ,
I am trying to build a Sample web service using Xfire and spring which will return some string(Test Service).

ClaimContactDataService.java

public class ClaimContactDataService  extends BusinessService  implements  IClaimContactDataService {

	
public String getClaimContacts() throws BusinessServiceException   {
		// TODO Auto-generated method stub
		return "Test Service";
	} 
}

IClaimContactDataService.java

public interface IClaimContactDataService extends IBusinessService {

	String getClaimContacts() throws BusinessServiceException;
}

To generate wsdl: It is generating.

Src/Integration-client-ab.xml

<bean id="claimContactDataBusinessServiceClient"	class="org.codehaus.xfire.spring.remoting.XFireClientFactoryBean"

public class Client {

		XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
				.newInstance().getXFire());

		String claimURL = "http://localhost:8280/.../claimContactDataService";

		try {
			IClaimContactDataService srvc = (IClaimContactDataService) factory
					.create(srvcModel, claimURL);
			
			  String response = srvc.getClaimContacts();

When I try to call webservice using client I am getting following error, Please help.

I am through with above null pointer exception.

But I am facing another error , can any one give inputs ?


Thanks in advance...........

I haven't muched played with Xfire web services and spring, but by the sounds of it, it looks like Xfire didn't return you a proxy to what you think you were getting, so you're trying to cast and invoke on the wrong type?

Spring AOP has a few different ways of 'weaving' (that's the term to decorate code with AOP). You might have better luck reading the spring documentation on how that works, or posting on the Spring forums specifically.

Deliverance: Your are great your inputs made to think In right direction, actually I cofigured wrongly. I rectified my issue.

Now I want to design a client for a webservice which is designed In .net.

WSDL: .net webservice WSDL url looks like
------

Code:

http://abc.net/Service.svc?wsdl

Can any one give tips how to design client using Java, Spring and Xfire to call a .net webservice?

Thanks,
Dev.

Yes.

If you build using maven, I'm sure they also have generate-sources goals. You'll have to make sure the .NET wsdl is hosted and accessible, and there's not really much else. the guide is simple, and the tools are very similar if you ever choose to switch to say Project Metro (JAX-WS, JAX-B, WSIT, etc), Apache Axis, Apache CXF, etc.

[java_dev]

I am using Xfire-all.1.2.6.jar,


Ant taks:

<target name="gen-client" description="generates client">
		<taskdef name="wsgen"
			classname="org.codehaus.xfire.gen.WsdlGenTask"
			classpathref="build.classpath" />

		<wsgen outputDirectory="${basedir}/target/generated-source"
			wsdl="http://a/b/Service.svc?wsdl"
			package="com….business.service" overwrite="true" />

	</target>

When I ran above take I am getting;

gen-client:

BUILD FAILED
\workspace_ws\Integ\build.xml:456: java.lang.UnsupportedClassVersionError: org/codehaus/xfire/gen/WsdlGenTask (Unsupported major.minor version 49.0)

Do I need to change classname(org.codehaus.xfire.gen.WsdlGenTask)? Here any input for me?
