[jboss-user] Error occured during JSP compilation in JBoss 5.0

[Ashish SHUKLA]

Hi all,

While trying to view a jsp page I've deployed in a WAR (inside an EAR), I'm 
getting following error:

---->8---->8----
01:55:08,585 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 30 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type 
JspFactory

Following is an excerpt from the generated java code (with line numbers):

----8<----8<----
28   public void _jspInit() {
29     _005fjspx_005ftagPool_005fc_005fif_0026_005ftest = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());
30     _el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory();
31     _jsp_instancemanager = org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(getServletConfig());
32   }
---->8---->8----

 From the Google search, I've concluded that this could be due to the 
classloading issues. So I checked my EAR, to see if there is any system-provided 
jar is deployed, but I found none. Then I started the JBoss with java's 
-verbose:class switch, and found the javax.servlet.jsp.JspFactory is loaded from 
the "jsp-api.jar" file shipped with JBoss.

---->8---->8----
% ./run.sh |fgrep JspFactory
[Loaded javax.servlet.jsp.JspFactory from jar:file:/home/dev/jboss-5.0.0.GA/common/lib/jsp-api.jar!/]
[Loaded org.apache.jasper.runtime.JspFactoryImpl from jar:file:/home/dev/jboss-5.0.0.GA/server/default/deploy/jbossweb.sar/jbossweb.jar!/]
[Loaded org.apache.jasper.runtime.JspFactoryImpl$1 from jar:file:/home/dev/jboss-5.0.0.GA/server/default/deploy/jbossweb.sar/jbossweb.jar!/]
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
----8<----8<----

Any ideas how to troubleshoot this issue ?
