Problems with BP PLM 50.3.1

Dear Reader

I have download the BP 50.3.1 for Products/Assets/Projects --> migrate them into a EP 6.0.

At the Backend R/3 i have 2003.1 Plugin and a

Portal Plugin: WP-PI.

The Iview's works fine, but when i select a material which holds a document i have a NullPointException.

This NullPoitException is caused by an applet class (downloadapplet.class), which could not be found.

Now i found this class in a package of BP but why the class is not found by the iview?

Material without a document doesn't cause this Exception.

The SAP-Note 642775 which include latest information about general installation prerequisites and configuration

for EP 6.0 does also not exist.

I'm confused with this thing!

(sorry for my english, i try my best)

Regards

Waldemar
