    error deploying simple session bean

    Matthew Purdy Newbie

      i created a simple EJB2 HelloWorldSessionBean and deployed it into jboss 4.2.3 java 6 build (when it failed, i also tried jboss 3.2.7 - got the same errors) and I got the following errors:

      system: mac book pro running windows vista 64 service pack 1
      server: jboss 4.2.3 build using java 6
      java: java 6 update (build 1.6.0_06-b02)
      dev env: eclipse 3.4 using ant to build jar file

          You have typed the classnames wrong in the ejb-jar.xml. For example, your jar contains prj/ejb2/HelloWorldSessionHomeLocal.class whereas you have mentioned (a non-existent) prj.ejb2.HelloWorldHomeLocal class in the ejb-jar.xml
