[jboss-user] [EJB/JBoss] - Trouble building simple EJB

[tamscot]

Hi, just going through an example ejb and then adapting the method used to create my own bean. Trouble is when I edit the main Bean class, in this case JujitsuFacadeBean, it comes up with some parse error and starts to create an interface in the ejbModule package.

IDE is Eclipse 3.2. 
JDK is 5.
xdoclet is 1.2.3
Jboss is 4.0.5.

i followed the example as per the book. Where am I going wrong?

Here is the errors reported in the console...

  | Buildfile: /home/tam/workspace/JuJitent/.metadata/.plugins/org.eclipse.jst.j2ee.ejb.annotations.xdoclet/tempAnt.xml

This is the code for JujitsuFacadeBean, this implements the interface JujitsuFacade whose jar file has been included in the project.

Suprisingly the build after editing starts to assemble an interface JujitsuFacade...terribly.
 
  | /*
  |  * Generated by XDoclet - Do not edit!
  |  */
  | package com.jujitsu.ejb;
  |  
  | /**
  |  * Remote interface for JujitsuFacade.
  |  * @generated 
  |  * @wtp generated
  |  */
  | public interface JujitsuFacade
  |    extends
  | 
Thats as far as it got.

Any help appreciated.
