Karl Wright commented on CONNECTORS-1070:
-----------------------------------------
Hi Kamil,
When you removed combined service from tomcat, did you use the manager UI? If
you didn't you also need to manually remove the expanded directory made from
the war in the tomcat work area. Otherwise, the web application is still
active.
You can prove this, by the way, by doing this:
- shut down all mcf processes
- lock clean, if you are still using file locking
- start ONLY the first agents process
- look at the log
If there are no errors, you can start the second agents process (if you are
using it), and once again look at the log. If that is OK, then use the
start-webapps script to run the right wars under Jetty. Once again check for
errors. If no errors, then it is your tomcat setup that is still causing
problems.
I think at this point you should maybe start with a fresh instance of tomcat.
Use the manager application to deploy the war files. Do not deploy the
combined war.
Thanks.
