My Webapp should be migrated from JBoss 4.0.3SP1 to 4.2.1.
It uses MyFaces/Tomahawk 1.1.5/Jbpm 3.1.
After a number of modifications I get my Webapp startet without Exceptions.
But invoking the first web page results in an error message:
javax.servlet.ServletException: Unable to compile class for JSP:
An error occurred at line: 63 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
Stacktrace:
javax.faces.webapp.FacesServlet.service(FacesServlet.java:155)
de.ems.fleetoperator.application.web.AuthenticationFilter.doFilter(AuthenticationFilter.java:137)
org.jbpm.web.JbpmContextFilter.doFilter(JbpmContextFilter.java:83)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
I guess that's to do with incompatible jsp-versions. But how to approach a solution?
