Subject Tomcat 6 lib jars
Date Thu, 05 Dec 2013 14:42:16 GMT
Hi,

I've come across lots of duplicate jars in the tomcat/lib directory on the servers we have
been given by our infrastructure people.

The directory looks like this:

-rw-r--r-- 1 root root   15153 Jul 20  2011 annotations-api-6.0.24.jar
lrwxrwxrwx 1 root root      26 Oct 29 17:05 annotations-api.jar -> annotations-api-6.0.24.jar

You'll notice generic jar names sum linked to specific jars AND the specific jar also in the
directory. 

Is this harmless? Or should I ask for a 'cleaner' install from the apache website? I believe
this installation comes from the central CentOS6 repository.

Thanks
