javac task and dependancies

[Mark Binau]

Howdy Y'all,
I am new to using ant. I am using it to build applet jar files. The way I'm doing this is by creating a temp directory and using the <javac> task to compile the main applet class to a destination of the temp directory. When I first did this <javac> would conveniently compile all of the dependancies to the temp directory and then I would use <jar> to zip it up.
When I first did this I was using ant 1.4.1 which came with WSAD 5.0. Now I am using ant 1.5.3 which comes with WSAD 5.1.0. Now <javac> does not compile the dependancies. Can one of you ant / java compiler gurus please explain to me why this does not work any more?
Is it related to the upgrade of WSAD? I pass in an argument of:
-Dbuild.compiler=org.eclipse.jdt.core.JDTCompilerAdapter
Is there another argument I can pass in which would make it compile the dependancies again?
Do you have some other slick way of compiling applet jars?
Please help!
Thanks in advance,
Mark
