Hello

I finally clean the NPE using gdb. :)
Till now, I am not sure where exactly the qtopia influence kaffe, but now I
could run a plain text helloworld in the embeddedkonsole of qtopia now.
The NPE was due to some initProperties,
in function(System.c) :
struct Hjava_util_Properties*
java_lang_System_initProperties(struct Hjava_util_Properties* p)
...
#if defined(HAVE_LC_MESSAGES)
	locale = setlocale (LC_MESSAGES, "");

	tmp = strchr (locale, '_');
#else
	tmp = NULL;
#endif
...
And we just closed the HAVE_LC_MESSAGE macro in config.in to make it work.

But now we still couldn't pass the AWT test...
Maybe we have post the similar question many times,
but I still hope some could give me a hand as soon as possible.

QtAWT: getNextEvent..   

-------------------------------------------------------------------
And then nothing more happened...
The cpu seemed not busy too...
And I couldn't find the END SET VISIBLE, is that the trick??
I tried many test programs, but no difference.
Anyone who had successfully run kaffe awt over qtopia on an arm-box??
What should be my problem??
I am really in a hurry, because the time is flying...

Cheers,
Saw
