I am trying to deploy a web app (EAR/WAR) that uses XSQL. If I include xercesImpl-2.2.1.jar, JBoss won't deploy (SAX Parser issue). If I exclude that jar, the app deploys, but i get two issues: 1. It complains about not being able to find the jdbc driver, but executing the page a second (and subsequent) time works. 2. I get this execution error: file:/C:/Products/jboss-5.0.1.GA/server/default/tmp/5c4o5k5o-rxi2ue-fruwltla-1-fruwnk24-9m/ontrack.war/reports/manifest/container_lbl.xsl: XML-22043: (Error) Extension function error: Method not found 'generate' | I suspect this is caused by an incompatibility between the org.apache.xerces.* classes in JBoss vs the ones in xercesImpl-2.2.1.jar ? Has anyone successfully used XSQL with JBoss 5 ? Thanks, Craig. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214656#...
