Sessions lost when using apps on different non-clustered JBoss instanced behind Apache

Issue

I have loadbalancer based on Apache and AJP and application servers behind it. One of apps is OpenSSO running on one set of servers, it uses JSESSIONID cookie to locate servers. The other app is running other servers, it's also using JSESSIONID.
It looks like when I try to access my app sso creates cookie JSESSIONID with session ID and node route. I think Apache doesn't know which JBoss server it should be used, because JSESSIONID contains this information only for SSO, not for my app. So sticky sessions are not working with JBoss based app, both servers are used.
