Put your EJB jar in an EAR file and put your shared classes
in APP-INF/lib and APP-INF/classes

Your ear file will look something like this

app.ear
--------------

APP-INF/lib/utils.jar
APP-INF/classes/Util.class
META-INF/application.xml
myejb.jar

This in all probability sounds like a class loader visibility problem. Make sure that DOM4J / related XML parser classes are not present in Weblogic's app server common lib areas / along with weblogic.jar. If present, it is trying to load it via appserver's root class loader and it is not finding it, because you have placed it inside a child loader's classpath.
