FOP & JBoss & Oracle Apex

Add the missing Oracle XML Parser v2 (you may find them e.g. in JDeveloper/lib) libraries (lib/xmlparserv2.jar, lib/xml.jar) by opening the fop.war with your favorite zip program (e.g. rename fop.war to fop.zip) and saving the libraries WEB-INF/lib. Then copy the fop.war to the e.g. jboss\server\default\deploy directory. Maybe you have to restart your application server (dependent on your settings). Then try http://your-hostname:your-port/fop/apex_fop.jsp (e.g. http://127.0.0.1:8080/fop/apex_fop.jsp) to see if your work was successful.
