I am getting the following exception when I try to access a simple jsp
page. I am running JBoss 2.2, Tomcat 3.2.1, and Apache 1.19. JBoss and Tomcat
are running in the same VM and Apache is talking with Tomcat through mod-jk
using ajp 12.
I created a simple ear file containing 1 enterprise bean, 1 servlet and 1 jsp
file. The jsp file just has a link to the servlet and the servlet calls a
method on the EJB. When accessing the servlet directly, everything works fine,
but when I call the jsp i get a NullPointerException.
