Receive uploaded image / video (byte array) from j2me on jsp.HOW???

[angelicsign]

currently i'm trying to do a project, it needs to send upload a video to the server and store inside a folder. But i found that it just able to receive a set of data that < 1024bytes, i done that by uploading an image. the code i found is like that.

from this code, how should my jsp coding be done to receive the data sent by j2me?
by modifying the code,i just manage to get a chunk of 1024bytes of a total of 42986bytes image.
can some body help me?
this is urgent for me.thanks...
