Tomcat 6 lib jars
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

lrwxrwxrwx 1 root root 38 Oct 29 17:05 tomcat-juli.jar -> /usr/share/tomcat6/bin/tomcat-juli.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

Dan,
+1. I can't imagine what kind of headaches are waiting around with all the
symbolic links for the JARs.

Minimally, I would ask for an up-to-date version of Tomcat. The libraries seem to indicate that 6.0.24 is installed and that's pretty old now. As for the latest 6.0.x release.
As far as the duplicate JAR files, one situation off the top of my head where it could cause problems is if the versions are different. For example, if the JAR file in the lib folder is version X and the symlink points to version Y. This is problematic because you would have no idea which version of the JAR is going to be loaded. You'd want one or the other, either the file or the symlink.
Personally, and I think many people on the list would agree, I'd suggest against using the installation from your distro's repository. They're typically way out-of-date (see my comment above) and they tend to put files in weird places. At least weird relative to the standard installation that is available from tomcat.apache.org. While having files in weird places may not directly cause problems, it does make it more difficult for people on this list to help when you have a problem.
