helloworld, sample program all can't run, and shows the same error

[neoaries]

mine is netbeans 6.5, and i installed wtk 2.5.2 for eclipse. I'm satisfied with netbeans 6.5 doing my j2ee projects, it worked quite well, its sun java application server integrated with netbeans is quite nice and convenient, but what's going on with it when doing helloworld and sample programs in j2me!?

btw, other ppl can run the same program without error....quite frustrated...


My error is:

Did you change the Ant version you are running on? NB6.5 has Ant 1.7,
where deleteonexit is supported.
Could you give more light how you build the project?
