Jboss summing-up

1. org.apache.jasper.JasperException: Unable to load class for JSP
<%@ taglib uri="/WEB-INF/tld/iextend-multiParamsLink.tld" prefix="multiParamsLink" %>
JBoss cannot found iextend-multiParamsLink.tld file and cannot digest this jsp. JBoss doesn't throw a clear message.

2. Maybe I have config jndi correctly, But when starting jboss, below exception was thrown.
javax.naming.NameNotFoundException: While trying to lookup 'jdbc.XXX' didn't find subcontext 'jdbc'. Resolved ''; remaining name 'jdbc/XXX'
