Help_tomcat4124+apache2.40+MODJK2

[Ingmars Rubenis <in...@lu.lv>]

Hello!

I am using Apache 2.40 built  in RedHat Linux 9.0  with tomcat 2.1.24
and mod_jk2
Here are configuration see below after error message.
I use 2 tomcats with 2 load balancer.
I think I have also sticky sessions.
Where Can I configure session length in uPortal?
 I think it does not wok, here
are  errors
