How to programmatically search text in jar file?

I want to search my sources.jar for the occurrence of a certain search token.

In Bash, this will extract the jar to a stream and grep for the string:

unzip -p sources.jar | grep $SEARCH_TOKEN

In Java, reading all entries via JarInputStream looks rather tedious. Is there a better/simpler way (for both, the looping and the grepping)?

In short, No (probably).

(I guess you might get lucky, and find an existing Java utility command someone has already written. I don't rate your chances though.)

It is your lucky day!
