Now, with more parameters!

#!/bin/sh

if [ $# != 2 ]; then
echo "Usage: `basename $0` path string"
exit 1
fi

jars=`find $1 -name \*.jar`

for i in $jars; do
if jar -tf $i | grep $2; then
echo JAR: $i
fi
done

Thanks for pointing that out. I admit I did that script while reading
the bash scripting How-To. Overall I think it wasn't bad for five
minutes of study and trial and error. I so seldom write shell scripts,
nothing sticks in my brain.

Hy,

I suggest you this site http://www.jarvana.com/jarvana/

You can use Jarvana site to search for classes and their associated
jar files to resolve NoClassDefFoundError and ClassNotFoundException
issues.
Source code and javadocs can be viewed when available.

Classes, artifacts, and content in the maven central repository are
searchable. You can obtain dependency information for classes and
artifacts, inspect POM files, and inspect plugins.
