Using JDK 6 style classpath with javac ANT compile task

Question

Does anybody have an example of using JDK 6 style - only defining the directory and not list of each and every jar in the directory - classpath with an ANT javac compile task?

We tried it like this

compile.classpath=c:....\WEB-INF\lib*;...websphere...\a.jar;...websphere...\b.jar; etc. and used this classpath in the javac task, but the libraries from WEB-INF\lib were not being recognised.

So, I am wondering if it is possible to use this type of construct with ANT. The ANT version is 1.8.4.

Typically we use path like structures .

<path id="project.classpath">
   <fileset dir="${libdirectory}">
       <include name="*.jar"/>
   </fileset>
</path>

The the project.classpath is used in javac task. See more at ant examples

This is how the task is defined now in the working build. But this construct expands it to the complete list of jars in the directories. ( This make the classpath really big - about 5k characters ) With JDK 1.6, that is not necessary. With JDJ 1.6, we should be able to just list the directories with /* instead of listing all the jars in it. – adbdkb Sep 24 '12 at 11:12

I do not yet know, why this works vs. why it doesn't work without these attributes, but I was able to get the wildcard part to work by using the fork="yes" and executable="path-to-my-executable" attributes in the javac task.
