ClassCastException after return entity from slsb method with
Hi!
I am using EJB 3 quite a while and with JBoss 4.0.3SP1 everything was working fine. So I updated to 4.0.4RC1... well here is my question: I have an pretty simple stateless session bean with a method
public UserEntityBean findUserByUsername(String username) {
UserEntityBean user = em.find(UserEntityBean.class, username);
System.out.println(user);
System.out.println(user.getUsername());
System.out.println(user.getPassword());
System.out.println(user.getEmail());
return user;
}
When I call this method from within a struts action via
InitialContext ctx = new InitialContext();
UserFacadeLocal facade = (UserFacadeLocal) ctx.lookup("um/UserFacadeBean/local");
System.out.println(facade.findUserByUsername(username));
I get the following exception
10:09:44,265 ERROR [STDERR] java.lang.ClassCastException: neu.ejb.UserEntityBean 10:09:44,266 ERROR [STDERR] at $Proxy73.findUserByUsername(Unknown Source) 10:09:44,266 ERROR [STDERR] at neu.struts.action.UserAddAction.execute(UserAddAction.java:36) 10:09:44,267 ERROR [STDERR] at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) 10:09:44,267 ERROR [STDERR] at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) 10:09:44,267 ERROR [STDERR] at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) 10:09:44,267 ERROR [STDERR] at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) 10:09:44,267 ERROR [STDERR] at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) 10:09:44,269 ERROR [STDERR] at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) 10:09:44,269 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) 10:09:44,269 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) 10:09:44,269 ERROR [STDERR] at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) 10:09:44,269 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) 10:09:44,269 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) 10:09:44,270 ERROR [STDERR] at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) 10:09:44,270 ERROR [STDERR] at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) 10:09:44,270 ERROR [STDERR] at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:54) 10:09:44,270 ERROR [STDERR] at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:174) 10:09:44,270 ERROR [STDERR] at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) 10:09:44,270 ERROR [STDERR] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) 10:09:44,271 ERROR [STDERR] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) 10:09:44,271 ERROR [STDERR] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) 10:09:44,271 ERROR [STDERR] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) 10:09:44,271 ERROR [STDERR] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:868) 10:09:44,271 ERROR [STDERR] at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:663) 10:09:44,271 ERROR [STDERR] at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) 10:09:44,272 ERROR [STDERR] at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) 10:09:44,272 ERROR [STDERR] at java.lang.Thread.run(Thread.java:595)
In jira I found something similiar http://jira.jboss.com/jira/browse/EJBTHREE-174 but there no solution is posted there. And as posted there using
public Collection<UserEntityBean> getAllUser() {
return em.createQuery("from UserEntityBean u").getResultList();
}
works fine.
I hope someone can help me. Thanks!
