Problems with JavaScript compression

Hello,

we use the Echo2 framework by NextApp for our web frontends. It supports AJAX an makes use of JavaScript compression.

I deployed an Echo2 test application successfully to SAP Web AS. But it doesn't run properly. There seems to be a problem with the JavaScript compression. Instead of the Script a bunch of cryptic characters arrives at the client side.

I tried to enable JavaScript compression like described in

but without success.

Does anybody has a clue how I could solve this problem?

regards

Daniel
