I want to use 32 bit java runtime on my 64 bit Ubuntu 12.04 system. jre installation includes configuration of the java plugin for the firefox. is there any compatibility issues I should know about?

Just make sure that Firefox can find the 32 bit Java plugin file (libnpjp2.so) by placing a symlink in a location where Firefox scans for plugins.
Firefox doesn't see the java plugin! This is what I did:
0. //ubuntu amd64: install g++-multilib
1. # cp jdk-6u35-linux-i586.bin /opt/java/
2. # cd /opt/java/
3. # ./jdk-6u35-linux-i586.bin
4. # update-alternatives --install /usr/bin/java java /opt/java/jdk1.6.0_35/bin/java 100
5. # update-alternatives --install /usr/bin/javaws javaws /opt/java/jdk1.6.0_35/bin/javaws 100
6. # update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so /opt/java/jdk1.6.0_35/jre/lib/i386/libnpjp2.so 100
7. # update-alternatives --config java
8. # java -version
9. $ JAVA_HOME=/opt/java/jdk1.6.0_35/
10. $ export JAVA_HOME
11. $ PATH=$PATH:/opt/java/jdk1.6.0_35/bin
12. $ export PATH
13. $ javac
In addition to the fact, that Firefox actually doesn't see the java, there's also a problem with JAVA_HOME and PATH variables - they only save their values for the current session.

Up.
Anyone?
May be this will do:
6. # update-alternatives --install /usr/ lib64 /mozilla/plugins/libjavaplugin.so libjavaplugin.so /opt/java/jdk1.6.0_35/jre/lib/i386/libnpjp2.so 100

Which version of Firefox do you have installed?
A 32 bit or a 64 bit version?
If you run a 64 bit version of Firefox then Firefox needs a 64 bit Java plugin (lib64) and a 32 bit Firefox needs a 32 bit Java plugin (lib32), otherwise it won't work.

You are speaking of pretty obvious things.
Let me remind your first answer: [QUOTE] Just make sure that Firefox can find the 32 bit Java plugin file (libnpjp2.so) by placing a symlink in a location where Firefox scans for plugins. [\QUOTE]
Why do you change your answer like this?
I do not know which Firefox version you currently have installed.
I assumed the normal 32 bit version, but I might be wrong about that.
So please confirm which version you have.

What's the point of this topic? - how to keep compatibiliy with 32-bit java applets under 64-bit firefox ?? This is the point.
You say this is impossible? :-\
