Technology Preview SAP NetWeaver 04 for linux broken?

Hi,

I downloaded the "Technology Preview SAP NetWeaver 04 - SAP Web Application Server on Linux" from this site and followed the installation instructions.

There were no problems during the server installation. Everything I tried so far worked.

The installation of the SAP NetWeaver Developer Studio did not work however. During the 1st installation I got the message:

c:\program files\common files\sap shared\sapchart.ocx

c:\program files\adobe\designer 6.0\filesystembrowser.dll

could not be installed. To view the log, open

file://Y:\J2EELX1\IDE\setup\saplogvw.exe.

Unfortunately I cannot find the the program saplogvw.exe.

If I start the developer studio, I encounter two problems:

I can change the perspective once, for instance to development configurations. From there I cannot change the perspective any more. In the console I get the error message:

An error has occurred restoring the coolbar layout. java.lang.IllegalArgumentException: Argument not valid

Unhandled exception caught in event loop.

[...]

I did the 1st installation on a linux box with SuSE linux 9.0. The server is on the same box.

Then I tried a 2nd installation of the developer studio on a laptop with windows 2000. The laptop is connected to the linux box though a local network. The installation went through without errors. I also can change the perspectives repeatedly without getting any exception. However, I cannot connect to the server. I set the message server parameters of the SAP J2EE engine to

host: nw4host

port: 3601.

With tcpdump I can see, that the developer studio does not send any IP packets through the network, i.e. it does not try to connect to the server. And I cannot login, e.g. in the development configurations, because the "login" is disabled.

With a browser, I can connect to the server, however.

What did I miss?

Thanks for any help in advance,

Andreas.
