Add session bean problems

Question

i tried to add session bean sets, but when i reach the 'configure EJB methods' dialog box, i cannot proceed to click on button 'finish' because of the errors "one or more collection element types are not specified: [getAuthorizerId] ".
how to fix it??? thanx.

Answer 1

this is the getAuthorizerId methods that i have written.
public List getAuthoId (String code)throws HibernateException{
          Session ses = null;
               try{
                    boolean trace = logger.isTraceEnabled();
                    if(trace)
                         logger.trace("Begin to search Authorizer code " + code);                    
                    ses = ThreadLocalSession.currentSession();          
                    Query query = ses.createQuery("from Authorizer as authorizer where authorizer.authoId=?");
                    query.setString(0, code);
                    List result = query.list();
                    ses.flush();
                    if(trace)
                         logger.trace("End of searching authorizer code " + code);
                    return result;
               } catch (HibernateException e) {
                    ctx.setRollbackOnly();
                    throw new HibernateException("Unable to search authorizer code " + code, e);
               }finally{
                    try {
                         ThreadLocalSession.closeSession();
                    } catch (HibernateException e1) {
                         e1.printStackTrace();
is it because jsc cannot support java.util.list??
