[SOLVED] Can mod_jk and mod_proxy run together in the Apache ?

I tired to google about it but couldn't find the answer. After searching so long my Basic Instinct ;-) say it cannot be done but still to be sure can both modules mod_jk and mod_proxy run together in Apache server without creating problem ?

Can you summarize your use case here? The answer technically "no", there shouldn't be problems but depending on how they're being used could cause a problem.

I have the apache server running tomcat with mod_jk and the mod_proxy was installed by default in it. I have not stop mod_proxy so I feel I am getting the error in logs files saying "request failed: error reading the headers" because of it.

No, it's not mod_proxy. If you're not using it you can disable it by adding a # in front of the "LoadModule proxy_module ..." directive(s) in apache config file.

do does it mean mod_proxy and mod_jk cannot run together ?

Sure they can coexist. By that I mean that they both can be loaded into apache and serve different things.
You can use mod_jk to parse jsp pages or servlets by a tomcat server and mod_proxy to proxy some backend server. Note that the backend server is not necessarily the same tomcat. It can be a different tomcat or a complete different server (like a webmail server).

What I don't think is correct, is to use both modules to parse the same URI. E.g. something like that:

Code:

JkMount /foo/* ajp13
...
ProxyPass /foo/ http://tomcat.server:8080/foo/
...
