How do I use the 32-bit JVM on a 64 bit OS?

Question

I have a 64-bit server with only 1 GiB of RAM (VM at Rackspace). I need to run a few instances of the JVM, and the 64 bit VMs are consuming too much RAM. I can't seem to find anyplace that tells me how to install the 32-bit packages of openjdk. When I run with -d32, I get told:

# java -d32 -version
This Java instance does not support a 32-bit JVM.
Please install the desired version.

When I run with -client, I still get the server VM:

# java -client -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.2) (6b22-1.10.2-0ubuntu1~11.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

Is it even possible to use the 32-bit client VM on 11.04?

Solution

You can download 32-bit versions of Oracle Java for Linux.

These don't come as Debian packages; download the .tar.gz version and unpack it somewhere, and then add the bin directory of the JRE to your PATH.
