Hi,
I am trying to migrate my application from
jboss 2.4.X to Jboss 4.0.I have prblem deploying my EJBs.I added the below tag to the ejb-jar.xml.
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd">

While the deployer tries to deploy my application,I get the following errors.Please not that the same .jar file is properly working on the JBoss 2.4.x.
