upgrade diablo jdk1.3 to jdk 1.4.2 on Freebsd 4.9

[Carla Neves]

Hello,
How do I upgrade my diablo jdk1.3 to jdk 1.4.2 on Freebsd 4.9?

I currently have installed on my machine:

       diablo-jdk-1.3.1.0_1 Java Development Kit 1.3.1
       jakarta-tomcat-5.0.18_1 Open-source Java web server by Apache, 
5.0.x branch
       javavmwrapper-1.4   Wrapper script for various Java Virtual 
Machines

And I would like to upgrade the jdk to jdk1.4.2, but unfortunatly I 
couldn't find the port diablo-jdk-1.4.2 to upgrade. So that makes me 
wonder if can I use the port  /usr/ports/java/jdk14 and de-install the 
diablo jdk-1.3.1. 

Does anybody can help me?


Best Regards,
