Can Apache OfBiz be installed with an existing version of Tomcat

Question

I installed Tomcat last year with mod_jk for Dashbuilder. I'd like to install OfBiz which also uses Tomcat but it appears that Tomcat is included in the OfBiz files.

How can I run Tomcat with mod_jk for a reverse proxy and multiple applications such as OfBiz and Dashbuilder?

Configurations:

apache conf file

JkMount /dashbuilder* worker1
JkMount /someapp2r* worker2
JkMount /someapp3* worker3
JkMount /ofbiz* worker4

workers.properties

worker.list=worker1, worker2, worker3, worker4,status
worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=127.0.0.1
worker.worker1.port=8009

worker.list=worker2
worker.worker2.type=ajp13
worker.worker2.host=127.0.0.1
worker.worker2.port=8009

worker.list=worker3
worker.worker3.type=ajp13
worker.worker3.host=127.0.0.1
worker.worker3.port=8009

worker.list=worker4
worker.worker3.type=ajp13
worker.worker3.host=127.0.0.1
worker.worker3.port=8009

# Status worker for managing load balancer
worker.status.type=status

Error With an existing Tomcat 8.5 running with mod_jk for other applications

Error after turning off the exiting version of Tomcat 8.5 and tried to run ofbiz.

I searched for worker and found this but it might or might not be relevant.

I think using external Tomcat is no longer supported OOTB since R9.04. Please refer following thread .

You can also use Apache OFBiz user mailing list for such queries.
