Searching through Jar Files to Find a Specific Class

Troubleshooting


Problem

There are times when programming in Java or debugging Java applications that you need to know if JAR files is a directory contain a specific class file. This document describes a method to quickly search through JAR files within a directory to find specific class files on the iSeries.

Resolving The Problem

A simple QShell script can be used to search through jar files to find a specific class. The syntax is as follows:

for x in *.jar; do echo $x; jar -tvf $x | grep -i search_string; done;

To use this command, do the following:

1.Type QShell using the STRQSH command.
2.Change to the directory where the jar files exist using the cd command.
3.Run the script, replacing the search_string parameter with the desired search string.
For example, this sequence searches through jar files in the CommerceServer55/wc.ear directory for any class that contains OrderItemDataBean. Six matching classes are found in 2 jar files.

STRQSH
===> cd /qibm/proddata/commerceserver55/wc.ear
===> for x in *.jar; do echo $x; jar -tvf $x | grep -i OrderItemDataBean; done;
