Re: which class can i use?

[Dorothy Wu]

Thanks for Chris Gray's answering.

I have read some documents on kaffe web site, 
I think I have had some ideas about my project.

And I want to reference some examples of kaffe.
Where can I find java(kaffe) application group?

Thanks,
Dorothy Wu

which class can i use?

[Dorothy Wu]

hello, 
I am a newbie in Java field and planning a java project by kaffe.
It is an application running in linux.
Now I am a question about programming,
Can I use xt lib?
Is there any "class" implementing x function?
Or can I use the other library(.so) which compiled by c/c++ compiler?
I am at a loss.

Thanks for any help!

[Dorothy Wu]

hello!

Could u help me check the below code?

When I write in ta(TextArea), nothing print out( System.out.println(evt) ).

error when system.load()

[Dorothy Wu]

hi,
I met a problem when I use JNI.
 
I wrote two shared 
libraries (c/c++).
Then I used them in my c/c++ 
application.
Everything is Ok, my c/c++ application can use 
these libraries.
 
But when I use it in kaffe by JNI,
Only one library can load, another can never loaded 
by System.load().
Error is:
"UnsatisfiedLinkError: file not 
found."
 
I have checked the path, everything is 
OK.
The difference between these two libraries is,  the 
latter do not link any library.
The link command is:
"ld -shared --whole-archive x.o y.o -o 
libxy.so"
I do not think it is the reason why I can not load 
it.
 
But why, it is a bug of System.load()?
 
Thanks!
