Jervis,
Thanks for your reply.
The interface code is as follows:
package com.fm.services;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.WebResult;
import org.codehaus.jra.Get;
import org.codehaus.jra.HttpResource;
import java.util.List;
@WebService
public interface IService
{
@Get
@HttpResource(location="/images/{searchString}")
@WebResult(name = "result")
public List<Image> doService(@WebParam(name="searchString")
String
searchString);
}
The implementation class is as follows:
package com.fm.services;
public class ServiceImpl implements IService
{
public List<Image> doSearch(String searchString)
{
List<Image> results = new ArrayList<Image>();
// Populate the results
return results;
}
}
If I change the List<Image> to a List<String>, I see the same exception from
my client. The rest invocation from a browser returns the correct values
though.
Thanks
Sriram
