I have my own jar, a small reporting engine that saves versionned reports into the database built on java 1.4 This reporting engine uses hibernate and has some entities in it. I would like to use this reporting engine as is in a web application that uses JBoss Seam. What is the approach for achieving this. Do I need to build an extension on top of that archive to make it compatible? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082899#...
