[jboss-user] [JBoss Seam] - Re: Seam component instantiation problem

[klsateesh]

Hi,

  I am also having an issue with the Instantiation of the Seam Component..

  I am trying the HelloWorld App in examples/remoting..

  In the JBoss Server log i see the component..


  | 
  | 13:43:42,828 INFO  [Scanner] scanning: /D:/Projects/DPA/Jboss4.0.4/server/default/tmp/deploy/tmp43419MySeamTest.ear-cont
  | ents/MySeamTest-ejb.jar
  | 13:43:42,828 INFO  [Component] Component: helloAction, scope: STATELESS, type: STATELESS_SESSION_BEAN, class: org.jboss.
  | seam.example.remoting.HelloAction, JNDI: MySeamTest-war/HelloAction/local
  | 13:43:42,984 INFO  [Initialization] done initializing Seam
  | 
  | 

Note: i have created an EAR App (MySeamtest) in NetBeans and hence the name MySeamTest.ear..

And when i run the App it is accepting the User Name and the  throwing the following Exception..

I have added the following context parameter to web.xml


  |    <context-param>
  |         <param-name>org.jboss.seam.core.init.jndiPattern</param-name>
  |         <param-value>MySeamTest-war/#{ejbName}/local </param-value>
  |     </context-param>

Thanks
