Robert,
Since most of your questions are general Java questions and have
nothing to do with the Linux port of the JDK, can you please direct
them elsewhere? The USENET group comp.lang.java.programmer is probably
a good place to ask.
Thank you,

Hi Robert,
Adding the final keyword to a variable in an argument list only
means that the reference is final, ie you can't make the reference refer to
another object. I does not mean that I can't call certain methods in the
same way as C++.

I am pretty sure, if you remove your libhello.so library
completely from your directory, you are going to get exactly
the same message. It means that your loader cannot find your
library libhello.so, even if it is in the directory.
I don't think LD_LIBRARY_PATH matters. Verify that you

Yeah, gcj is a Java front end for the gcc compiler: Java goes in, native

I've been using jdb (through JDE) on the Blackdown 1.2 JDK since it's been

works perfectly for me, if slowly.

Hi,
It was the article in one of the Java magazines two years ago.
I don't remember which one. They claimed that for numerical
operations the speed was comparable.
In very crude and simple loop test on Linux with gcc -O3
and Blackdown Java (I assume jit was on) the ratio Java/C
speed was 3 - 4

Although not directly relevant to the Blackdown JDK, GCJ (the Java front-end
to GCC) supports Java debugging with GDB. This is amazingly useful

Hi,
Does anybody know comparable benchmarks for Java, C and C++ tasks?
I am interested in comparative speed of the languages - any platform
is good. So far I heard only about two years old Java/C++ comparison
on NT, which stated similarity in speed under some conditions.
Thanks,

Robert,
How about creating a class like this:
"public class Fred{
public static final ResourceGizmo resourceGizmoRef;
}"
Then in the main class or init code do Fred.resourceGizmoRef=new .
Then any class can access the instance by using Fred.resourceGizmoRef.

Hi Robert,
the "standard answer" I guess: use the Singleton-Pattern (see "Design
Patterns" by Gamma, Helm, Johnson and Vlissidis) like this:

private static Gizmo instance = null;
private Gizmo() {
}
public static Gizmo getInstance() {

its a good idea.

IMHO pure jdb from terminal with some patience is a nice choice, especially
if threads debugging. There is a jd from alphaworks. It's a java written,
and
quite robust.

Ctrl-\ or SIGQUIT will give you a "thread-dump" of the jvm. Consider it
