Is weblogic 8.1 compatible with JDK 1.5?

Hi All,

We have a requirement to update our server with JDK 1.5. We also have weblogic 8.1 running on that server. Would this activity come up with any compatibility issue?

Thanks in advance.

WebLogic Server 8.1 supports JDK 1.4. You will need to migrate to at least WebLogic Server 9.0 in order to run JDK 1.5.

Hi Roger,

Thanks for your replay. Migrating from weblogic 8.1 to weblogic 9.0 might be a complex activity for us, as so many application are deployed on weblogic 8.1.

Do we crate a domain which can use anyway jdk 1.5?

You can have multiple JDKs installed on a server. Why would the presence of JDK 1.5 affect your WebLogic Server 8.1?

I bet your weblogic8.1 server can not run on java 1.5.

This is a business process , first try to migrate the projects deployed in 8.2 to 9.2 , it doesnt have so much complexity because server JDK5.0 have can accepts 1.4 too,but 1.5 in weblogic 8.1 is may not be possible

There's no need to guess or bet if it will work or not.

Look at the documentation from BEA, especially this: Supported Configurations for WebLogic Platform 8.1.

WLS 8.1 is only guaranteed by BEA to work on the operating systems and JVM versions listed in the tables on that page. It might work on a newer JVM or it might not - either way, it's not guaranteed by BEA so it is not recommended to try it in a production environment.

Just so you all know. I have tried using JDK 1.5 for weblogic8.1 and it gives some Exception like AssertionException when I start weblogic.
