Webservice error

[z_idane]

Hi,
I am trying to extend a stateless sesssion bean BookSearchActionService to webservice.
After deploying, when i try to invoke the webserice. I get following error.

java.lang.IllegalArgumentException: Wrong target. class webservices.action.BookSearchActionService for public webservices.beans.Book[] webservices.action.BookSearchActionService.searchBooks(java.lang.String)

Here is my SLB code

package webservices.action;

import java.util.ArrayList;

import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import webservices.beans.Book;
@Stateless
@WebService(name="booksearch",
 serviceName="booksearch",
 targetNamespace="URN:ejbmodule.bookserch")
@SOAPBinding(parameterStyle=ParameterStyle.WRAPPED,style=Style.DOCUMENT,use=Use.LITERAL)
public class BookSearchActionService {

 @PersistenceContext
 private EntityManager mgr;
 @WebMethod(operationName="searchBooksByAuthor",action="searchBooksByAuthor")
 public Book[] searchBooks(String author) {
 ArrayList<Book> list = (ArrayList<Book>) mgr.createNamedQuery("findBooksByAuthor").setParameter("author", author).getResultList();
 Book[] books = new Book[list.size()];
 for (int i = 0; i < list.size(); i++) {
 books = list.get(i);
 }
 return books;
 }

 }

Am I missing anything here ?
thanks in advance.

When i use java premitives/Strings as IN OUT paramters, the service displays no malfuntion.
Is there anything missing when deploying ejbs as webservices which pass
java objects in its methods ?

[z_idane]

Solved.

Solution :

Do not use overriden methods in SLSB which extend as Webservice.

I was using method searchBooks which was overridden.

You might want to bring this up in the WebSerives forums probably http://www.jboss.org/index.html?module=bb&op=viewforum&f=200. If this is reproducible with just EJB3 beans then let us know. And please mention the JBoss AS version when you create a new post in the Webservice forum
