Problem while uploading large documents from Java Application, OT web Services hosted on IIS

Hi,

I am not able to upload larger documents (size > 20 KB) on Content Server using Java Application.

The OT Web Services are hosted on IIS. I am using same code stuff mentioned in the sample LL Tree View Java.

I have all the necessary settings under web.config of the les-services, Also, I am able to upload files upto 2 GB using Dot. Net Client application.

This is the Error Message i am getting -
