Sometimes we need to know in which jar file a particular class resides, and the location of that jar file.
We can find out using jarscan utility.
It can be downloaded from here
I had to find out which jar file contains this particular class

I downloaded the jar file from the link given above and placed in bea installation directory and executed the following command
java -jar jarscan.jar -class weblogic.security.spi.AuthenticationProviderV2
I got the output as follows
