JarScanner

Being able to find the jar file that a given class or package is in can be a life saver. Attached to this page is a utility which allows you to scan jar files to find a particular class or package.

Download jarscan.jar

Put the jar file in C:\JarScanner\

As an example, the following command would search starting in the "C:\WebSphere\PortalServer" directory for the java class "SystemProperty"...

java -jar C:\JarScanner\jarscan.jar -dir c:\WebSphere\PortalServer -class SystemProperty

For Help, type the following command:

java -jar C:\JarScanner\jarscan.jar -help
