Question

What is the correct way to write code to do the following:

Base64 base64 = new Base64
base64.getClass().getSourcePackageAndVersion() // ???

I’m trying to detect in my current Grails project if I am getting Base64 from
commons-codec-1.3.jar or commons-codec-1.4.jar. Is there a way to force it to use the 1.4 version while in debug / dev mode?

Answer 1

You can find the jar file or classes directory the class is loaded from with this:

base64.getClass().protectionDomain.codeSource.location

or since you already have the class:

Base64.protectionDomain.codeSource.location
