Copied my reply from your other post at http://www.jboss.org/index.html?module=bb&op=viewtopic&t=134611
My guess is that an XML file is validated which references a DTD or XSD unknown to JBoss, so that the parser tries to load it from the internet.
Could you verify this? Does it work with an internet connection?
It seems you use an EJB 1.1 ejb-jar.xml. The required DTD is in the "docs/dtd" directory of JBoss ("ejb-jar.dtd"), but I don't know how to tell JBoss to use those DTDs.
Please post the header of your "ejb-jar.xml" with the DOCTYPE declaration.
By the way: the DOCTYPE declaration should be like this:
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN" "http://java.sun.com/dtd/ejb-jar.dtd">
See file "server/default/conf/jax-ws-catalog.xml" for the mapping of SystemID to local DTD/XSD files.
