    Webservice error

    Mayuresh Chaubal Newbie

      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 ?

                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
