I've installed and set up Tomcat 7.0.21. I followed Tomcat 7.0 documentation on using the special tasks List, Reload, Install, and Remove. Here's the build.xml snippet:

<path id="compile.classpath">
<fileset dir="${catalina.home}/bin"><include name="*.jar"/></fileset>
<fileset dir="${catalina.home}/lib"><include name="*.jar"/></fileset>
</path>

<echo message="${toString:compile.classpath}"/>

<taskdef resource="org/apache/catalina/ant/catalina.tasks" classpathref="compile.classpath"/>

Here's what happens when I try to execute any of the special tasks i.e. List:

[pgarner@localhost Patrac]$ ant -version
Apache Ant(TM) version 1.8.2 compiled on December 20 2010

[pgarner@localhost Patrac]$ echo $CLASSPATH

As you can see, all three of $CATALINA_HOME/lib/catalina-ant.jar:$CATALINA_HOME/lib/tomcat-coyote.jar:$CATALINA_HOME/lib/tomcat-util.jar:$CATALINA_HOME/bin/tomcat-juli.jar appear in the class path, above, which I echoed from within Ant. Now, watch this:

[pgarner@localhost Patrac]$ export CLASSPATH=".:$CATALINA_HOME/lib/catalina-ant.jar:$CATALINA_HOME/lib/tomcat-coyote.jar:$CATALINA_HOME/lib/tomcat-util.jar:$CATALINA_HOME/bin/tomcat-juli.jar"
[pgarner@localhost Patrac]$ echo $CLASSPATH
.:/usr/share/tomcat/lib/catalina-ant.jar:/usr/share/tomcat/lib/tomcat-coyote.jar:/usr/share/tomcat/lib/tomcat-util.jar:/usr/share/tomcat/bin/tomcat-juli.jar

Why can the List target not see the needed JAR files on its class path unless I set it in my Linux user environment? I don't want to have to add an export CLASSPATH entry in .bash_profile. I should be able to set the class path for executing an Ant task inside of an Ant build script. What am I not understanding here?
