Thank you for the help. Using LD_PRELOAD, I was able to change the error
quite a bit. Now it fails after starting the JVM because the current

Hi Peter!
Yes! There are!
First to find out the partition do: fdisk -l. In fact fdisk is one of the
few mechanisms you can use to manipulate partitions under linux.
Second for disk size and free space do: df. Read the man for each of them as
they provide lots of usefull information.
Take Care!

There is no real difference between JNI on Linux and JNI on other
operating
systems (and not suppose to be). Look at Sun Java tutorial on JNI:
http://java.sun.com/docs/books/tutorial/native1.1/index.html
Take the source code for HelloWorld example and follow the instructions:

We're wandering OT here, but I hope this is useful to others dealing
with JNI/C++ integration...

And what might that symbol (or some of those symbols) be? That info

Sun Tutorial is not for Linux. If you use JNI on SGI, you have to use -shared
too.

That creates an executable, to build a shared library you have to
add the '-shared' option.

It should be in a directory right under whereever jni.h is. Depending on
the platform you use, the directory should be "linux", or "solaris" etc. You
should have that path in your include path as part of your -I
compiling option.
Good luck.

JNI on Linux is much the same on all platforms( more or less:).
If you want a good book on JNI I suggest you try 'Essential JNI' by Rob
Gordon. It'

Hi,
To use JNI you only need the blackdown JDK.
I have attached some files how i always test the JNI on Linux:
C++ calling JDK 2 Awt.
the almost same example works with JDK 1.1.7 as well.

Hi,
I cannot answer your questions directed to the porting team, but I would
strongly recommend the 1.1/1.2 JNI model (there are some small
extensions in 1.2). There are two major reasons:
1. libraries using the 1.1 model are to some extend portable between
platforms and should be fully portable
Hi,
i used a symbolic link to point to the JDK 1.2pre2, this crashed my

The netwinder's a cute little machine developed by Corel computing
canada. It has the SA1100 (strong arm) processor which used to be
made by DEC but is now produced by Intel.

The combination AWT and Invocation API doesn't work currently.
It should work with the next release.
