i do think it is the java machine problem, am i right?

I just installed the java development kit using apt-get install j2sdk1.4 and found this using apt-cache search java. You will need this in your /etc/apt/sources.list:

#java
deb ftp://ftp.tux.org/java/debian/ unstable non-free
deb ftp://sunsite.dk/mirrors/java-linux/debian/ testing non-free

but you want stable, so try

#java
deb ftp://ftp.tux.org/java/debian/ stable non-free
deb ftp://sunsite.dk/mirrors/java-linux/debian/ stable non-free

Then run apt-get update so apt-get know where to get the java files from. Then try:

apt-get install j2re1.4 java-common azureus

This should install a stable java and azureus (fyi I have just started azureus and seems to be running quite smoothly!)

Hope this works for you, if it doesn't, try using unstable java or something...

i have one more question....

how to uninstall the j2re i downloaded and installed earlier from www.java.com (that is a bin file with no instruction on howto uninstall itself.......)

Just remove the directory which the bin file created. The bin file creates one directory containing the Java runtime.

Installing Java using the Sun binaries is actually quite convenient. Different users can use different Java versions, one user can install several Java versions (which version starts can be controlled using the PATH environment variable), etc.

On mandrake it used to install itself to /usr/java (then jre-[version])
so i spose you could type "ls /usr/java" and if it exists then you could type "rm -rf /usr/java"

Brilliant page on installing Java on Debian:
