A problem was found when installing JDK on rhel 5.6. the newly installed version does not work properly and always shows the same version when viewed with java-version.

Java version "1.4.2"

Gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-50)

# rpm-qa | grep jdk

Jdk-1.4.2-fcs

# rpm-e-- nodeps jdk-1.4.2-fcs uninstall it

4. Then set up the java directory under usr and install the new jdk

First upload the jdk-1_5_0_22-linux-amd64.bin installation package to / usr/java

#. / jdk-1_5_0_22-linux-amd64.bin
