Can I run a Java 32-bit application on a 64bit system

Question

Natty 64-bit is installed. iMindmap 5 a Java 32 program will not run correctly.

Is installing 32-bit Java a possible solution?

Solution

It should be possible - obviously you will need to manually flip between 64bit or 32bit Java depending upon the application you will be using:

Using the ‘Ubuntu Software Center’ just search for ‘Java 32′ and install (if not installed) the 32-bit JRE. Currently it is called ‘ia32-sun-java6-bin’.

Next open your terminal window and and run:

sudo update-alternatives --config java. 

This will you give you various versions of Java running on your Ubuntu machine. Simply select the 32-bit instance of the JRE you prefer and press enter.

Next we need to check that we have the right version of Java running. Do this by entering java -version in the terminal window.

You should see similar output as:

java version “1.6.0_07″
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Server VM (build 10.0-b23, mixed mode)

Yes it should work.

or use update-java-alternatives which is a shortcut, specifically for java.

Can we run 2 application at a time when 1 uses 64-bit Java and another uses 32-bit Java?
