title: errors deploying an EAR with EJBs 2.1 into JBoss AS5
body: <p>I'm porting an application with EJBs 2.1 from Weblogic9 to JBoss AS5. I have made some of the changes like adding jboss.xml descriptors to EJBs and fixing application.xml of the EAR, but there are still problems when deploying the EAR. Here is a summary of the the latest error I'm getting when the first EJB is being deployed by JBoss (I will add the full stack trace at the end of the message):</p>

  <p>Is this a problem with parsing the jboss_2_4.dtd itself? or is it something worng with my descriptors for the EJB?</p>
  
  <p>When I try to validate the jboss_2_4.dtd in an XML editor it does complain about a syntax error at line 94:1 , which is the beginning of the first  declaration, although it looks fine. Any ideas?</p>
  
  <p>Thanks!</p>
