Error while downloading code into robot

[RoboElite640]

I get an error while downloading the code from netbeans to the robot. The error code comes out as:

C:\Documents and Settings\Developer\sunspotfrcsdk\build.xml:95: The following error occurred while executing this line:

ummmm.... why java?
and for the answer- try to find a veteran team or professional programmer to look over your code

I'm not as familiar with Java as with C++ or LabVIEW, but I think it's an issue with the connection to the robot for uploading code, rather than one with the code. The upgrade script updates the code on the robot with the current Java code, and "Socket operation on nonsocket" indicates an issue internal to the Ant script, though it may indicate a misconfiguration of the script.
