How to insert a class file inside 100s of jar

Hi ,
have 100s of jar file where I need to insert a class file to them in bash script.
what is the best way to automate that?

1. Is it possible to inject without extracting the jar?
2. Would like to find <file_pattern>.jar recursively and inject
3. pls help with sample scripts

Thanks in advance
