JAVA in UBUNTU 8.04LTS?

Question

Hi friends. I am a java learner. I need to learn java in Linux.

I have UBUNTU 8.04 LTS installed. How to get java for it, install, and work. Pls suggest me in this matter.

Answer 1

you should enable the Universe repository in Add/Remove programs, and install either the openjdk-6-jre package or the sun-java6-bin package.

Choosing the default Java to use

Just installing new Java flavours does not change the default Java pointed to by /usr/bin/java. You must explicitly set this:

    * Open a Terminal window

    *      Run sudo update-java-alternatives -l to see the current configuration and possibilities.

    *      Run sudo update-java-alternatives -s XXXX to set the x*x java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun

    *   Run java -version to ensure that the correct version is being called.

You can also use the following command to interactively make the change;

    * Open a Terminal window

    *  Run sudo update-alternatives --config java

    * Follow the onscreen prompt

hope this will help

cheers:)
