I attended the Oracle Fusion Middleware 11g Forum in Bridgewater, NJ. It was a pretty informational session and I got to talk directly to Oracle management about some questions I had regarding Oracle’s Portal and JVM Strategies. (more…)

My takeaways from Oracle Fusion Middleware 11g Forum
Wednesday, July 29th, 2009Can WebLogic 10.3 run on JDK 1.4?
Wednesday, July 29th, 2009One of my colleague asked me whether he can upgrade to WebLogic 10.3 from WebLogic 8.1 and not upgrade his JDK to 1.6. (more…)
Java 1.4 and WebLogic 8.1 End Of Life
Saturday, July 12th, 2008As you might already know Sun announced End Of Life for JDK 1.4 to be October 2008. Since WebLogic 8.1 runs only on JDK 1.4, BEA announced EOL for WebLogic 8.1. This is the statement from BEA Support site.
After the EOL date, WebLogic Server and WebLogic Platform configurations that run on J2SE 1.4.2 will no longer be running on fully supported configurations. BEA will continue to support these environments on a best-effort basis. Lack of support from an SDK vendor, however, may limit BEA’s ability to resolve certain SDK-related issues.
If you care about not using EOL products in your Application stack, you have 2 Options and a dilemma to deal with.
Option 1:
The obvious, migrate your application to JDK 5 or greater. This depends on the complexity of your application, for all you know all you have to do is deploy your application to WebLogic 9.x or 10.x and fingers crossed your application with run flawlessly.
Option 2:
If you believe you cannot make the October 2008 deadline, contact Sun and see if you can extend your support contract to include support for JDK 1.4. If you have some extra budget you probably would go with this easiest no hassle option, atleast for now.
Dilemma:
Well, the dilemma is if you upgrade to WebLogic 9.x or 10.x, you will have to upgrade again in October 2009, because both these versions of WebLogic only support Java 5 which is going EOL in October 2009.
There is no WebLogic version out there that supports JDK 6 yet, from my reliable sources WebLogic Server 10.3 is slated for release end of July, 2008.
My Suggestion:
If your application uses the base WebLogic Server, I would wait for 10.3 release and migrate to it hoping that 10.3 is released on time. You will have 3 months to migrate giving you an ample time to test and deploy your application. If you are using WebLogic Platform products like WebLogic Portal or WebLogic Integration you may have to wait for those products to be released, since these Platform products are usually released a few months after the base WebLogic Server is released.
If you cannot wait until 10.3 is relased, BEA made the Technology Preview of WebLogic Server 10.3 available. You can download it and test your application to make sure you do not see any major issues.
