Siemens S55 Emulator + Netbeans

Hello!

I am new to j2me and also new in using netbeans.
I am trying to connect the siemens s55 mobile phone emulator to netbeans 3.5.1.
The problem is, that everytime i try to execute the test program (HelloMIDlet) with that emulator, the emulator starts up and on the virtual mobile phone is written: “Error/One or more MIDlet class(s) not found: HelloMIDlet”
But if i just start the emulator as standalone and then load the .class file which was compiled during the execution try in netbeans, the Hello World Program works.

If it helps, here is my configuration:

Windows XP
J2SDK 1.4.2
Netbeans 3.5.1 with following modules installed:
kjava.nbm (J2ME Wireless)
kjava-emulator_win.nbm (J2MEWTK 1.0.4 Win)
kjava-obfuscator-retroguard.nbm
kjava-obfuscator-jode.nbm
Siemens SMTK (0.13.2.59) and S55 Emulator (V0.12.11) installed and chosen as Default Emulator in the Runtime Window of Netbeans
J2ME Wireless Toolkit 2.1 installed.

Netbeans works flawless with the emulator integrated in J2ME Wireless Toolkit 1.0.4 and 2.1.

In the Programmer Reference from Siemens it is written, that the emulator should work with Sun One Studio with the above mentioned modules installed.
So it should also work in Netbeans with the same modules, or?

Any help is appreciated.

So long, Kai.
