Struts Upload & WebSphere : Premature end of stream while reading multipart request

[Kevin HOVER]

Hi,
I'm using the Struts 1.0.2 : the WAR Upload example works fine on WSAD 4.0 (IBM WebSphere Studio Application Develloper) but when I try to run it on WAS 4.0 (IBM WebSphere Application Server - Advanced) I keep getting this I/O exception :

Error Message: IOException while reading file element: 
Premature end of stream while reading multipart request
Error Code: 500
Target Servlet: null
Error Stack: 
java.io.IOException: Premature end of stream while reading 
multipart request

I've figured out that the the problem comes from Struts trying to write a temporary file on the server : MultipartIterator.createLocalFile(...). The thing is Struts apparently can write the beginning of the file in the temporary directory (I've checked if it was actually created) but looses the I/O Stream before the end. It never does this under WSAD and always does it under WAS.
Can someone help, this is urgent . Thanxs.
