Hello Jason,
I have something similar to the following in my build.xml file:
<path id="myAll.class.path">
<pathelement location="${someDir}/myFirst.jar"/>
<pathelement location="${someDir}/mySecond.jar"/>
</path>
Then, inside the <java> and </java> section, I have:
<classpath refid="myAll.class.path"/>
I hope this works for you... as I am still learning the ins and outs of ant
build.xml files myself.
Thanks,
--Anna
