Tomcat is opening too many jar files? Any Fix

Recently we deployed one struts application into production, after sometime if we try to find out the list of jar files opened, it showing two many jar files opened can anybody tell me why this happening?

lsof | grep struts

is there any method to share the jar files?

TOMCAT_HOME\lib\

You can place shared libraries into above dir.

Maybe

• Multiple resources are read from the file
• You do hot deploy and handles are still open from previous application context

EDIT

Well, i'm not a unix guru but i assume "lsof" shows open handles. So, every time a file stream is opened or closed, this will change.
