Hello fellow java-linux users.
I have been working on an open source project that provides a
way to combine Java and the Tcl scripting languages using the
java reflection APIs. I was hoping I could get some help
testing the code to make sure it works on a number of linux
systems. To make a long s

The JVM spec is quite specific about this. There will only ever be one copy of
any code block. The compiler has no say in this regard as it's required to
produce
files compliant with the .class format, wherein the object data and the
code are
distinctly seperated. The JVM Spec is available online
Hi,
I think I'm going to go ahead with trying to write a little C program to
check which library versions a system has and give the user some
suggestion about what JDK file she should download. In order to do this,
I need some information about where systems keep their libraries and

What you've mentioned is known as method inlining.
The Soot framework does this optimization on Java classfiles. (Why
classfiles? See the technical report at

I would be stunned if there were (ever) a Java API for using shared

I have a couple of questions, one Linux-specific,
one not.
1. Has anyone written simple instructions on
how to extract the Java2 ORB and retrofit
it into JDK 1.1.7 on Linux? Or does anyone
have any experience in this area they would
like to share? Do I need to use idl2java

This sounds to me like Java and C/C++ native code can talk to each other
only if they (java and native code) are in the same thread. Is it right, or
in the same process?
