I was trying to create a weblogic webservie to send a list of custom vo's.

I was getting the following error. While calling it.

The issue was that the vo definition was not getting created if I used just the following

package tutorial.sample6;

import java.util.List;
import java.util.ArrayList;
import java.util.Date;

public class HelloWorldService{

public Object helloGenericWorld(){
return "Hi there";
}

public List helloListWorld(){
ArrayList list = new ArrayList();


Custom data = new Custom();
list.add(new Custom());
list.add(new Custom());

return list;
}



}

And the mapping is created if I add the following method and it works

So final code is

package tutorial.sample6;

import java.util.List;
import java.util.ArrayList;
import java.util.Date;

public class HelloWorldService{

public Object helloGenericWorld(){
return "Hi there";
}

public List helloListWorld(){
ArrayList list = new ArrayList();

Custom data = new Custom();
list.add(new Custom());
list.add(new Custom());

return list;
}

public Custom complexType(Custom data ){
return data;
}

}
