Second upload only 1kb?

i have a webservice that allows me to upload a file. When i do j-unit tests the upload is always correct. The file is written on the server.

When i try this according the NW2004 file upload/download tutorial then the first upload i do works. The second one works also or so it seems. Since the webservice is successfully executed, but it only writes a file 1000bytes on the server.

When i do a tcpTrace i can see that the total message size is correct ,but the content-length in the soap envelope is only around 1000bytes. This is the problem is guess. But i dont know why is the cause.

has anybody else experienced this also? I dont think this is a WebDynpro problem perse, but like i said, the j-unit test are working everytime.

Thanks all for helping out.
