Using native classes
Hi, How can I get a reference to a native class in a shared library and use the functions ? An example would be very welcome !! Thanks ... E-Mail : [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Solved SIGSEGV 11* !!!
I've got segmentation violation error while trying to run simple JNI program. I use RedHat 6.1, glibc 2.1, jdk117v3. I've read all the solutions in FAQ but nothing helped. Well, once more solution is to compile C library with -shared key.

Re: Using native classes
I've not seen a way to call say.. libc printf from java. printf is usually wrapped in a native function that matches java's calling method. More recently this is done through the java native interface. You have probably seen the 'trail' for calling native functions from java methods. http://java.sun.com/docs/books/tutorial/native1.1/index.html There are examples with source code of less trivial tasks on blackdown's products page.

Well there is a poor communication from Blackdown particularly in terms what they could have achieved from the web. There was JDK1.2 status page but it was poor compared to the efforts of Mozilla or even java.apache.org. Imagine we have all of this fabulous technology ... Ok nobody expected web designers, but they could recruited a good webmaster or content designer to keep all of us up to date on what was really going on. In other words get some more recruits. I am sure they could have found a volunteer to go act as go-between between the developers and the public list. I think I read somewhere that a Top Sun bloke did try to contact the blackdown list, but could n;t get thru. Reminds me of Banarama "Hanging on the telephone ..." If they 'd have asked for some perl scripts or java scripts to turn simple text changelog into a web page, then they'd have gotten em. I find it incredible that you can find out what "Alan Cox has been hacking today.", but you can't do they same for "Blackdown".

Re: another possibility wrt the press-release.
These are good and reasonable suggestions, but I hope we don't get into a game of could-of/should-of/would-of w.r.t. Blackdown project communications. The team communicated news when there was news, and did have to deal with a lot of persistent "when is it coming?" questions they could not answer. My point was that responsiveness has been a real problem. The reaction to this meltdown, "Inprise didn't try hard enough to reach us", has been disappointing and I continue to be disappointed by the Blackdown refusal to accept *any* of the responsibility for the disconnect with Inprise. It wouldn't be the end of the world to admit that mistakes were made, and to figure out how to prevent them in the future. I'd even be so bold as to suggest that doing so would make a cooperative project to merge all the fixes much more likely.

RMI without http server?
Hi Folks,
I'm hoping that some RMI guru can help
me get started. I'm trying to create a
simple RMI client/server on a single computer,
but something is choking in the rebind() call.
linux 2.0.38

try {
System.out.println( "main");
if ( System.getSecurityManager() == null )
System.setSecurityManager(new RMISecurityManager());
Server result = new Server();
Naming.rebind( name, result );
} catch (RemoteException e ) {
System.err.println("remote exception in main ");
e.printStackTrace();
} catch ( java.net.MalformedURLException e ) {
System.err.println("malformed url in main ");
e.printStackTrace();

remote exception in main
java.rmi.ServerException: Server RemoteException; nested exception is:

Any thoughts or pointers would be appreciated.
