Gentoo Linux has a very nice java integration; you can have more than one JDK<\/span> distributions in your machine and switch the VM in system-wide and per-user manner. To switch your current VM, you can simply enter ‘java-config —set-user-vm=VM<\/tt>‘ and that’s all.<\/p>\n

However, you need to know how java-config<\/tt> works if you want to add any JDK<\/span> which is not in the portage. It’s pretty simple to add a JDK<\/span>, but it can be tricky for a beginner. Please follow the following steps:<\/p>\n

    \n
  1. Install your JDK<\/span> somewhere. (e.g. 1.6.0.10-beta in \/opt\/sun-jdk-1.6.0.10<\/tt>)<\/li>\n
  2. Add the profile of the newly installed JDK<\/span> into \/usr\/share\/java-config-2\/vm\/<\/tt>. Copy from an existing one and replace some version numbers. (e.g. cp sun-jdk-1.6 sun-jdk-1.6.0.10; perl -pi -e “s\/1\\.6\\.0\\.03\/1.6.0.10\/g” sun-jdk-1.6.0.10<\/tt>)<\/li>\n
  3. Create a symbolic link to the JDK<\/span> directory in \/usr\/lib\/jvm\/<\/tt>. (e.g. ln -s \/opt\/sun-jdk-1.6.0.10<\/tt>)<\/li>\n
  4. Confirm that the new VM is recognized by java-config<\/tt> by typing ‘java-config -L<\/tt>‘.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
