Go to http://java.sun.com/j2se/1.5.0/download.jsp and get JDK 5.0 The file you want will be one ending in -i586-rpm.bin. Run it via:
$ rpm -Uvh jdk-1_5_0_03-linux-i586-rpm.bin
$ chmod +x jdk-1_5_0_03-linux-i586-rpm.bin
$ ./jdk-1_5_0_03-linux-i586-rpm.bin
$ rpm -Uvh jdk-1_5_0_03-linux-i586.rpm
Verify that it installed correctly by running:
$ java -version
Or, you here’s a nice script I found to check for you.
#!/bin/sh
if [ $UID -ne 0 ]; then
echo "You must be root to run this script"
exit 1
fi
ALTERNATIVES=/usr/sbin/alternatives
if [ -x $ALTERNATIVES ]; then
echo "alternatives program found"
else
echo "`basename $0`: alternatives program not found, aborting"
exit 2
fi

JAVA=`find /usr/java -name java | sort`

if [ -x $JAVAFILE -a -f $JAVAFILE ]; then
echo "java found as $JAVAFILE"
$ALTERNATIVES --install /usr/bin/java java $JAVAFILE 0
JAVAFOUND=1
LATESTJAVA=$JAVAFILE
fi
done
if [ $JAVAFOUND -eq 1 ]; then
$ALTERNATIVES --set java $LATESTJAVA
echo "java installed as $LATESTJAVA"
else
echo "java is not installed!"
exit 3
