Are you sure that you ProspectService application has no jsps? Try to comment out those JkMounts for AJP12. Also I would suggest to upgrade Tomcat, it looks pretty old. On 10/2/06, Durbha Murali - mdurbh <Murali.Durbha@xxxxxxxxxx> wrote:
The only JKMount that is relevant for our application right now is - JkMount /bankers/* ProspectService We are using Apache just as a pass-thru to the ProspectService. We are not running any servlets or JSPs. I think the rest of the JKMount lines can be ignored. Sorry about the confusion.
