Here is what I did to launch the install wizard.
CentOS uses the gih java interpreter. The WAS install script needs to launch the ibm interpreter. A jdk is included with the install package.
I executed the following to make the OS pick up the IBM java which I copied from the install package to /usr/.
alternatives --install /usr/bin/java java /usr/JDK/jre/bin/java 100
alternatives --install /usr/bin/jar jar /usr/JDK/jre/bin/jar 100
alternatives --install /usr/bin/javaw javaw /usr/JDK/jre/bin/javaw 100
alternatives --config java
the interface asks which java to use:
There are 2 programs which provide 'java'.
Selection Command
-----------------------------------------------
*+ 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
2 /usr/JDK/jre/bin/java
I enter 2 to select the IBM java
I did the same for jar and javaw
alternatives --config jar
alternatives --config javaw
I had to set execution permissions for these 3 files when they are copied into /usr/bin
In the etc/profiles file I added
export JAVA_HOME=/usr/JDK/jre/bin/java
export PATH=$PATH:/usr/JDK/jre/bin
The WAS wizard graphical UI does not launch so I used the responsefile with silent install and it went without a hitch in about 15 minutes.
I also had to install openmotif : openmotif-2.3.1-2.el5.i386.rpm so that the graphics work for the AST installer.
