The program is fast, secure, and reliable. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Itis a programming language and computing platform first released by Sun Microsystems in 1995. It’s also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing. Java Runtime Environment (JRE) allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. Finally, add the new JRE in Java->Installed JREs using the install location ( /usr/lib/j2sdk1.6-sun) and select it as the default.Java Runtime Environment 1.6.0.38 (32-bit) I also had to delete my ~/.eclipse directory or Eclipse wouldn’t start (this requires reinstalling new versions of any plugins). I had to reinstall the 32 bit version of Eclipse (since SWT contains native code). Java HotSpot(TM) Server VM (build 10.0-b23, mixed mode) Java(TM) SE Runtime Environment (build 1.6.0_07-b06) If you run java -version you should see the correct version: java version '1.6.0_07' It was installed at /usr/lib/j2sdk1.6-sun for me. Use update-alternatives to select the new JDK. For some reason the package name has the _amd64 suffix. You have to trick it into building the 32 bitĭEB_BUILD_GNU_TYPE=i486-linux-gnu DEB_BUILD_ARCH=i386 fakeroot make-jpkg jdk-6u7-linux-i586.bin deb package from theīinary you downloaded. At the time this was jdk-6u7-linux-i586.bin for me. Installationįirst, download the latest 32 bit JDK (not JRE) from Sun. I’ve been running Eclipse and all my development applications and finally have some free memory again. To install the 32 bit JDK from Sun on a 64 bit system you can use java-package. This package provides only the runtime environment (no javac) and theĬlient VM so it has limited usefulness for a developer. Needs, 32 bit Java is fine, even with a 64 bit kernel. If you’re runningĪ lot of Java processes this 64 bit tax is very noticeable. Of course they use about double the memory. 64 bit support is not bad now and most apps run You can recompile theĭesktop kernel with HIGHMEM64 set, but then you’re stuck building theĦ4 bit kernel. Server with different latency settings, etc. You can install the server kernel, but that’s been tuned for a – the default Ubuntu desktop kernel will only allow access to the firstģGB. You’ve probably had to figure out how to access that additional memory

If you have more than 3GB on your machine and you’re running Ubuntu
