Thanks Neil!

 For the rest please see bottom posting.

In reply to Neil:

# echo $JAVA_HOME
/usr/java/jdk1.5.0_05/

# echo $CLASSPATH

(nothing)

# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin:/usr/games:/usr/share/qt3/bin:/emul/ia32-linux/bin:/usr/java/jdk1.5.0_05/bin

This is as expected as I haven't set a CLASSPATH.

# which java
/usr/java/jdk1.5.0_05/bin/java

# which javac
/usr/java/jdk1.5.0_05/bin/javac


# java -version
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

# javac -version
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object


Where do you want me to run ls -la lib from?
ls -la lib (from the ProjectX top level build directory gives)

# ls -la lib
total 357

but I don't think that is what you mean.

Now. In partial answer to my own question:

I installed jdk from rpm via alien, as I prefer as miuch as possible to go
through dpkg/apt-get, and there is no  rt.jar anywhere on the installed
system, BUT:::
I also had a look at the jre tarball, and that DOES contain the rt.jar
class file. So the answer may be to download the jdk tarball and replace
the main java tree to see if that fixes it. Perhaps the rpm is broken.

What do you think?
