bash command: search for class in file system of jars

Question

I'm wanting to recursively search my maven repository (an n folder deep heirachy of jars) for a specific class inside an unknown jar.

jar -tvf myJar.jar | grep ClassIWant.class works great for a known jar but I'm having problems piping/chaining bash commands to achieve a recursive search.

Any hints much appreciated.
