How to Connect Apache with Tomcat for XI R2

system · June 10, 2006, 3:33pm

Attached is the zip file which contains a PDF document that gives detailed step by step instructions on how to connect Apache HHTP Server with Tomcat for XI R2 using mod_jk connector on windows platform.

Zip also includes Sample configuration files and mod_jk connector for Apache 2.0.54 server.

These instructions and the code has been tested and runs perfectly fine.

the instructions would help only when both Apache and Tomcat are on one machine.

Indeed but if you want to manage to do with Apache and Tomcat on different servers, you have to modify the workers.properties file as following:

# BEGIN workers.properties
# Definition for Ajp13 worker
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=your_tomcat_server
worker.ajp13.type=ajp13
# END workers.properties

Hi everybody!

We’re using the same configuration (one Apache as load balancer and three Tomcat linked using mod_jk on windows2k3 Srv).

We’ve started the configuration for authentication in winAD, follwing the “Configuring Kerberos manual authentication and/or SSO in distributed environments” manual found on SAP web site.
Everything is working fine execpt SSO via the load balancer.

We found, by sniffing, that we received the authentication token from the KDC but we get a “Bad gateway” error on the logon page.

We’re thinking that the problem is between the Apache and the Tomcat.
Here’re our config files:
