[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Howto - JBoss 4.2.1 & MyFaces 1.1.5

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? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4084708#...
