i can't get my EJB deployed in JBoss 3.x and JBoss 4.x while the same jar file is deployed fine in jboss 2.x.
it gives some error state invalid ejb-jar.xml
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
the above line need to be added to ejb-jar.xml
JBoss-2.x doesn't care while later releases 3.x, 4.x seem to be looking for it when parsing the ejb-jar.xml file
