The problem seems to be that JBoss5.0.1.GA precludes the use of libraries loaded in $JAVA_HOME/jre/lib/ext folder. I just discovered that in JBoss5.0.1.GA, I can get eh code to work by uploading the JAI libraries (jai_codec.jar and jai_core.jar) in the lib folder of the war deployment. JBoss4.x uses the libraries loaded in the ext folder seamlessly so the JAI libraries uploade in the ext folder are available to any war deployment. Is there a configuration setting that would allow using the ext folder in JBoss5.0.1.GA? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4219055#...
