upgrade java 1.4 to 1.5

Ubuntu 6.06

• Sun Java5: Install it from the Applications -> Add/Remove... menu making sure to check the unsupported and proprietary software checkboxes, or install the sun-java5-bin package.

• Blackdown Java2 1.4 packages: Install the j2re1.4 package, available in the multiverse repositories. Install it from the Applications -> Add/Remove... menu, or install the j2re1.4 package.

Kubuntu 6.06

• Sun Java5: Load up Konsole, and type:

sudo apt-get install sun-java5-bin

Accept the licence agreement that appears.

Note: The license may not come up and will cause the package installation to fail, to fix this, do the following:

• In a terminal, type

sudo apt-get install libqt-perl sudo dpkg-reconfigure debconf

• The first command will install the needed package for debconf-kde counterpart. The second command will ask a few questions: For the first step, choose "kde". For the second step, choose "high". Then, to fix the packages that did not correctly install, do:

sudo apt-get -f install

• then you are done.

• Blackdown Java2 1.4 packages: Install the j2re1.4 package, available in the multiverse repositories. Install it from the Applications -> Add/Remove... menu, or install the j2re1.4 package.

Note: Scroll down to "Selecting the default Java version" section to enable the JRE you have installed.
