log4j in J2ME

[Marcus Hock <mh...@gmx.net>]

Hi!

I have a problem running log4j in a J2ME-PersonalProfile Enironment.
I use CrEme, a Runtime Environment which includes a PDA-Env. and a Windows 
Emulator.
Everything compiles well (as J2SE is used for compilation) and it runs 
well in J2SE.
The Problem occurs in the Emulator / the PDA Environment:

Using the statement

  BasicConfigurator.configure();

I get the Error

------------>8------------>8----------------------
C:\CVS\final1>"C:/Programme/NSIcom JSCP V4.00/bin/pJSCP.exe" -classpath

So I tried:

  static Logger logger = Logger.getLogger(MP3cloud.class.getName());
[...]
  PropertyConfigurator.configure("sort1.properties");

Which produces the Message:

My question:
Is there any possibility to run log4j in the J2ME Personal Profile 
environment?
I've seen that several packages like java.util.logging, which is included 
in J2SE, do not exist in J2ME - is that package required?
Or is my problem the J2ME-PP runtime environment, CrEme (www.nsicom.com)? 
Any 'better' J2ME-PP RE's?

TIA for any answers,

Marcus Hock
