Sun's Java is now an official package in Dapper multiverse, so it may be easiest to upgrade to Dapper (very stable now).
The entire install process to install Eclipse and Sun's Java (on Dapper) is to install the following 2 meta packages: eclipse sun-java5-jdk
However, as noted Eclipse will now run very slowly since it will be using GNU's java, not Sun's. We now need to make Sun's java the default. First,
and select Sun's java. You might want to do the same for jar, javac, javadoc, javap, and javaws.
Next, edit the JVM configuration file
and move the line
to the top.
Lastly, Eclipse for some reason ignores Ubuntu's JVM configuration file and uses its own (bug?). You need to edit eclipes's java_home file
and add
to the top of the file.
That's it. Does anyone think I should post these instructions as a HOWTO ?

本文介绍如何在Dapper系统中安装Eclipse及Sun的Java,并详细说明了配置默认Java环境的过程,包括使用update-alternatives命令及编辑JVM配置文件等步骤。
