ok, how could we be getting jdk 1.5 java compile?
We removed (via control panel) the 1.5 jdk. could some file be lurking
in c:\winxp or other folder?
Below are parts of the log from the build:

I did notice an invalid entry in the PATH.
Should I check the CLASSPATH too?

You can certainly specify which JDK to use in the <javac> task.
However, that may not fix your runtime issue...if an older version of
the JDK is used to run against it...
Yes, specifying <target> may help...
Again, you need to ensure the VM being used when running against the
compiled class is the correct version (in your case I think that means a
1.4.2+ VM)...
It looks to me like your code is being compiled using the JDK 1.5.0+ I
just compiled some code and did a "javap -c -verbose" on a class
file... With the JDK 1.5.0_09 I get a minor = 0
major = 49... Compiling wiht "javac -source 1.2 release 1.2" I see the
minor = 0 major = 46.
My guess is the JDK being used during compilation is 1.5.0+. As such,
try doing the target = "1.4" ... You may also need to set source = "1.4"
