jartools

jartools is a command-line utility for examining java archives (JARs and WARs). It is a complement to (not a replacement for) the standard jar utility.

It is designed to use streams in the standard unix style so it can be composed with other stream-processing tools (e.g., grep, xargs).

jartools is distributed as a rubygem. Install it like so:

$ gem install jartools

Depending on how your ruby is installed, you may need root privileges to do this.

It's been tested on Ruby 1.8.7, JRuby 1.5.6, and Ruby 1.9.2.

To see what tools are included in the version you have installed, you can do this:

$ jartools help

To get details on a particular tool, use, e.g.:

$ jartools help packages

This online help tells you what arguments may be passed to each command.

Lists all the packages present in a JAR.

Prints the JAR's manifest (if any) to standard out.

Does a diff of two JARs or WARs, including file content diffs and recursive diffs of contained JARs.
