Ok, you're not far from the solution. You have to install WeakSSL add-on and setup the following parameter: ... param6="weakssl" value6="dummy" ... <PARAM NAME="param6" VALUE="weakssl"> <PARAM NAME="value6" VALUE="dummy"> Make sure you've closed all browser windows before testing.

Ok, the problem could come from one of the following: 1 - You've tested the process.jsp without modifying the directory variable and the compiled JSP includes the original path c:/uploads.

You want to avoid such filename or you want to rename it ?
