errors deploying an EAR with EJBs 2.1 into JBoss AS5 - ejb

Question

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):
14:15:48,124 ERROR [AbstractKernelController] Error installing to Parse: name=vf

....
Caused by: org.jboss.xb.binding.JBossXBRuntimeException: -1:-1 94:3 The markup in the document preceding the root element must be well-formed.
Is this a problem with parsing the jboss_2_4.dtd itself? or is it something worng with my descriptors for the EJB?
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?
Thanks!

I'd like to see your jboss.xml but I really wonder why you're using this very dusty jboss_2_4.dtd (the "JBoss 2.4 EJB deploymentDescriptor"). Since you're using JBoss AS 5.1, I'd recommend using the moderner jboss_5_1.xsd schema instead (see JBossDTDs for reference). Below an empty sample:
<jboss xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee
http://www.jboss.org/j2ee/schema/jboss_5_1.xsd"
version="3.0">
</jboss>
