Porting Applications from WebSphere to WebLogic?

Posted by Cliff on from the getting-comfortable-with-a-replacement-framework dept.

JFP queries: "I work for a division of a manufacturing company. We're currently running IBM WebSphere 3.5. We are considering a switch to BEA WebLogic 6./7. Has anyone had luck with IBM's upgrade path? Has anyone else ported a WebSphere 3.5 application to WebLogic? If so, how much of code did you have to rewrite? Are there any 'gotcha!'s that you ran into that you would care to pass along?"

    JBoss will be a relitively easy upgrade, since JBoss does not include any vendor extentions to Java. Therefore your app should be "vanilla" The websphere to weblogic upgrade could be more difficult, because there are vendor extentions. Any code which used that vendor extention will most likely need to be re-written.

    Java is write once run anywhere, but only if you stick to the standard. The standard doesn't do everything (yet) so the vendors have pushed the envelope (Just like the browser war)

    If you write to the standard you are fine. If you need/want the advanced features, be prepared for migration re-writes.
