How to remove unnecessary JAR files ?

my web application is Struts 2 based and also consumer of an axis 2 webservice.

There are unnecessary JAR files crowded in my my web application lib folder.

I want to remove unnecessary JAR files to clean up the system. I am not sure which JAR files to drop. I need assistance on this.

Please see the JAR file list in text file attached.

There are tools that can help you determine which Jars are actually in use, such as Tattletale:
http://www.jboss.org/tattletale/

You should be a bit careful when removing jars that appear to not be in use - as it is possible for code to be loaded dynamically (e.g. using reflection to construct instances) and these tools may not be able to see that sort of usage.

But if you run the tool, take out the apparently unused jars and then do a solid test pass that should be OK.

I have checked the site. I don't understand how to use this tool.

I have the LIB directory where all JAR's are there.

How do I use the tool from here ? is there any command to fire ?

What I found out there
You need to run following command at command prompt.
java -Xmx512m -jar tattletale-1.1.2.Final.jar app output
where app directory has jars and output is directory.
But it is not working on my machine. You can try.

This runs fine . I have run the command. I got a report file . name of the file is index.html in the output directory.

I attach the main report.zip file here. Please have a look at it.

by looking at this report, can you please suggest what actions I should take to clean up my system ?
report.zip

That "report.zip" file only contains the main index file to all the detailed reports. There is nothing of use in this report alone. You would need to zip up all the subdirectories of that "report" directory too.
