JAVA installation

Solaris 10 update 2 comes with jdk-1_5_0_06, update 3 comes with jdk-1_5_0_07, and both of them are working for all our applications all right.

RHEL4 came with 'jre-1.5.0-ibm' installed in /etc/alternatives, several symbolic links exist from /usr/bin. That JAVA gives errors compiling our programs, so we decided to install Sun version 1.5.0_06 (the same we have on Solaris machines). Maybe RHEL4 version is fine, just too peaky. Anyway following was done:

• 'jdk-1_5_0_06-*' files (for all supported platforms just in case) were downloaded from Sun web site to /usr/local/downloads

• file 'jdk-1_5_0_06-linux-i586.bin' was copied to /apps, and following commands executed:

chmod 775 jdk-1_5_0_06-linux-i586.bin
./jdk-1_5_0_06-linux-i586.bin
rm jdk-1_5_0_06-linux-i586.bin

• the number of symbolic links were hiden:

mv /usr/bin/jade 
mv /usr/bin/jadetex
mv /usr/bin/jar
mv /usr/bin/java
mv /usr/bin/javac
mv /usr/bin/javadoc
mv /usr/bin/javah

• and new links were created:

cd /usr/bin
ln -s
