Here’s a usefull tool: using JarJar you can easily find all the dependencies between the jar files you use. I’ve added a JarJar target to my ant build file to display these dependencies:

<path id="classpath">
  <fileset dir=".">
    <include name="**/*.jar"/>
  </fileset>
</path>
…
<target name="show.dependencies">
  <property name="lib.classpath" refid="classpath"/>
  <java jar="tonic/jarjar/0.6/jarjar.jar" fork="true">
    <arg value="–find"/>
    <arg value="–level=jar"/>
    <arg value="${lib.classpath}"/>
  </java>
</target>

Running this target result in the following output:

 ...
