Jakarta Commons Cookbook

1.3. Getting the Commons Lang Source Code

Problem

You want to view the source code for the Commons Lang project.

Solution

Download the source code from http://jakarta.apache.org/site/sourceindex.cgi. Following the same procedure as outlined in Recipe 1.1, you can download a file named commons-lang-2.0-src.zip (or commons-lang-2.0-src.tar.gz). Once you unzip this file, you will have the source to Commons Lang in ./commons-lang-2.0-src.

Discussion

The commons-lang-2.0-src directory will contain the following:

build.xml

An Apache Ant build file, which you can use to compile the source. If Ant is installed, you can compile or test by running ant compile or ant test.

src/java

This subdirectory contains the source for the classes in Commons Lang.

src/test

This subdirectory contains unit tests for the Commons Lang project. Each *Test.java file is an extension of JUnit TestCase class.
