tomcat6 with APR on RHEL5.5
The other day at $CLIENT I had to install a webapp that needed tomcat6 and I found it was quite a hassle to install a packaged version on a 32bits RedHat RHEL 5.5.
During that painful process, lefred helped finding the magic package that solved it all so I felt it was only fair for me to publish the complete solution as a guest post on his blog!
