Installing Java SDK 1.4.2 on Domino Server

I’m using Domino Server 6.5, and I have a java agent that needs some libraries from Java SDK 1.4.2.

Which steps should i follow to install new version of java on my server correctly?

Thanks,

Can’t really be done in a supported manner. Domino 6.x only supports up through JDK 1.3 (which is a big leap from the JDK 1.1.8 support in R5), and that won’t change until Domino 7 ships. You can certainly download the first beta and give it a try, though.

Best of luck, here are your options as far as I can see…

  1. Hire a brain surgeon, James Gosling and Ray Ozzie to help.

  2. Run the java code as a seperate app in it’s own VM as opposed to trying to get Domino to use 1.4.2 as it’s JRE

  3. Upgrade to Public Beta R7 which claims to support 1.4.?

I looked into doing something similar with the client and ended up crashing on startup every time…

You can’t: the JVM is tightly integrated within Domino/Notes and upgrades are not supported (mostly because of API stability).

You can try the following approaches:

  • External Java App with 1.4 JVM that uses Notes API to get to Notes.

  • In case of a web app: Servlet using separate container on 1.4 JVM, uses Notes API and/or Corba/DIIOP to get to Notes.

  • Port the required libraries to Java 1.3 (may be simple, may be horrific).

  • Find a 1.3 alternative.

  • Implement the required functionality yourself.

Keep in mind that using the Java Notes API is ofcourse only supported using Java 1.3, but it should work on 1.4 as well.

Upgrading is not an option, I’m afraid.
