General J2EE: Migrating EAR's from Websphere 4 to Websphere 6

  1. Migrating EAR's from Websphere 4 to Websphere 6 (1 messages)

    We are migrating our EAR’s from Websphere 4 to Websphere 6. We are planning to build a single set of EAR files that can be deployed to either WAS4 or WAS6

    In order to make this work, we need to keep all of the deployment descriptors compliant with J2EE 1.2

    When we deploy a J2EE 1.2 EAR in the Websphere 6 environment, the EAR is unable to connect to any V6 DataSources.

    Websphere 6 does not allow J2EE 1.2 EAR’s to use V6 DataSources. It appears that only V4 DataSources are allowed for J2EE 1.2 applications.

    Is there a way to override this? We would like to be able have the J2EE 1.2 application utilize V6 (not V4) DataSource’s.

    Thanks in advance.

  2. No, you can only use V4 datasources for J2EE1.2 applications.

    You should get rid (upgrade) of these WAS4 servers, keeping them will be much more expensive on the long run...
