Enterprise Java for Linux HOWTO 

2.2 IBM Java Developer Kit 

Background 

The IBM Java Developer Kit and Runtime Environment pass Sun s Java compatibility test and include the

latest maintenance.  (From the IBM website.) 

As of the time of this writing, the IBM Java Developer Kit is current with JDK 1.1.8 and is available only on

the Intel architecture. 

Download 

The IBM Java Developer Kit can be obtained from 

 http://www.ibm.com/java/jdk/118/linux

. 

In order to download, you will have to register with the IBM website and agree to the license online. 

The files available include: 

ibm-jdk-l118-linux-x86.tgz

 - The Java Development Kit contains everything you need to compile,

run, and debug Java. 

ibm-jre-l118-linux-x86.tgz

 - The Java Runtime Environment contains everything you need to run

Java. 

Since you will be doing Java development, I suggest downloading the ibm-jdk tarball file. 

Installation 

I suggest installing files in the /usr/local directory. After downloading the files, run: 

mkdir /usr/local/ibm

mv ibm-jdk-l118-linux-x86.tgz /usr/local/ibm

You can now open the distribution package.  To do this, type: 

tar zxvf ibm-jdk-l118-linux-x86.tgz

Under the /usr/local/ibm directory, you now should see  the jdk118 directory. 

The above example shows JDK 1.1.8 for the Intel architecture.  Substitute the filenames as appropriate. 

Setting up Your Environment 

The environment variables to set up are: 

JAVA_HOME 

PATH 

CLASSPATH 

The JAVA_HOME environment variable references the home directory of your JDK installation.  Set your

JAVA_HOME environment variable to the directory into which you just installed a version of the IBM Java
