Jar listing utility--Java archive file tool. Handling import errors easily in 4 steps.

Here is a quick example on how to get a database of what is contained in jars:
Step
1 of 4) Create a file containing:
#!/bin/bash
jarfolder=/usr/share
jarlist=/tmp/jarlist.txt
declare -a jarclass
find $jarfolder -name "*.jar" > $jarlist
for jarfile in `cat $jarlist`;
do
jarname=`basename $jarfile`;
jarfolder=`dirname $jarfile`;

jarclass=( $( jar -tvf $jarfile | awk '{ print $8 }' ) )
for aclass in "${jarclass[@]}"
do
echo $jarname $jarfolder $aclass;
done
done

2 of 4) Edit top 2 lines if needed/wanted.

3 of 4) Run the script and capture the output. You will get output like this:
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/events/SessionEvent.class
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/events/TransferEventSupport.class
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/events/SessionEventSupport.class
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/resource/Resource.class
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/Wagon$1.class
maven-core-2.0.6-uber.jar /usr/share/maven/lib org/apache/maven/wagon/Wagon.class

Note: The list has 3 fields: Jar file name, Jar path, Class name.
