Can I use Java 1.6 with WebSphere Application Server 6.1? IBM's website says no.

But I require Java 1.6 for a software application to be deployed and I cannot currently upgrade to Websphere 7.0, or use a different application server (WAS 6.1 is the org standard).

what are my options?

Thanks.

    You have no options, other than upgrading the appserver to something from the 21st century, or sticking with Java 5. Sorry. – skaffman Apr 05 '10 at 15:47
  • Others already answered, so just a thought: if WAS 6.1 is the org standard, then Java 1.5 is certainly also org standard, whether the org knows it or not. – zvone Jul 15 '10 at 23:04

Nobody can stop you from trying to run WAS 6.1 with Java 6 but this configuration IS NOT SUPPORTED by IBM and according to this thread, I'm not even sure you'll be able to start WAS.

    they must be doing something really interesting with the startup logic of the server if simply upgrading to a new JDK breaks the functionality – matt b Apr 05 '10 at 16:51

Since websphere 6.1 does not support J2SE 6, your options are very limited.

option 1

  • Talk to your upper management & convince them the need to switch to WAS 7.0

option 2

  • Downgrade your code compatibility to 1.5 and compile for J2SE 5.0

option 3

  • If you have a support contract with IBM, open a high priority ticket for getting 1.6 support on WAS 6.1
