junit task requires Java 1.4?

[Adam Mlodzinski <Ad...@quest.com>]

Hello, I'm getting the following exception when I try to run my unit
tests using JDK 1.3.1. What is the best way around this? Yes, I must use
java 1.3, in addition to 1.4 and 1.2.2. 
 
 Exception in thread "main" java.lang.NoClassDefFoundError:
java/net/URISyntaxException

My guess is to use a <java> task, specifying the operating parameters as
<arg>'s and <jvmarg>'s? But how do I get the results provided by
errorproperty and failureproperty, and how would I run a <fileset> of
tests?
 
Thanks for your time,
