Application error occurred during the request procession.

My develop studio's version is 2.0.20, my nw's version is 6.0.19, i think perhaps they need the same sps,so i update my j2ee engine to sps20,then rebuild the example,it is running sucessfull.

I rewrite the code. perhaps some error occour in my first codes.
