I just configured Apache - Tomcat and I'm trying to run an application and am getting the following exception:


exception

org.apache.jasper.servlet.JspServlet.service(jasper5-compiler-5.5.15.jar.so)
javax.servlet.http.HttpServlet.service(tomcat5-servlet-2.4-api-5.5.15.jar.so)

root cause

java.lang.NoClassDefFoundError: org.apache.tools.ant.Project
