In my build file I have this target:

<target name="JUNIT">
       <available property="junit.presesent"
classname="junit.framework.TestCase"/>
</target>

For some reason is says "Unable to load class junit.framework.TestCase to
set property junit.presesent". However I have junit paths set under Ant
properties:

netbeans.filesystems.path=C\:\\Documents and
Settings\\Administrator\\.netbeans\\3.5\\modules\\ext\\junit-3.8.1.jar;C\:\\
Documents and
Settings\\Administrator\\.netbeans\\3.5\\modules\\ext\\junit-testrunner.jar;
the same is set also for netbeans.library.path

I junit and ant should be installed correctly because they are both
installed through NetBeans.
