Question

I have been trying to get tomcat 6.0 to work on my local machine and have been unsuccessful. The server starts up normally, but when I try to view a page I get an exception:

SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 22 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

Stacktrace:

public void _jspInit() {
    _el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory();
    _jsp_annotationprocessor = (org.apache.AnnotationProcessor) getServletConfig().getServletContext().getAttribute(org.apache.AnnotationProcessor.class.getName());
}

Check that the libraries in your web application do not contain anything which Tomcat provides. Specifically, look out for JSP and JSP-EL libraries.

This problem reminds me of when Ivy was automatically importing the Spring JSP libraries and the servlet libraries which Tomcat really didn’t like.
