Problem with 2.4 and Sybase drivers [message #897391]

I am trying the new version of eclipselink, but there is a problem communicating with the sybase driver that I'm using. Unfortunately my workplace requires that we use the old jconn2.jar driver, which doesn't support the call getDatabaseMajorVersion() causing the following crash:

[EL Severe]: ejb: 2012-07-23 14:20:20.188--ServerSession(1686621532)--java.lang.AbstractMethodError: com.sybase.jdbc2.jdbc.SybDatabaseMetaData.getDatabaseMajorVersion()I

I have searched and found that upgrading to jconn3 or 4 solves the problem, but I am unable to upgrade due to my workplace restrictions. Note that everything works fine with 2.3.0, but migrating to 2.4.0 doesn't work even without any modifications to my code.

Hello,

This call is made when the database platform to use hasn't been specified and must be detected from the datasource. To avoid this, you will need to specify the database directly using the "eclipselink.target-database" property with a value of "Sybase" or "org.eclipse.persistence.platform.database.SybasePlatform".

The change to use getDatabaseMajorVersion() was added to 2.4 for bug 357569. Please file a bug to have it use getDatabaseProductName as it did in 2.3 when getDatabaseMajorVersion() is unsupported.

Best Regards,
Chris

Thank you very much for the reply, it all works now. (Edit, I had an error here previously but it was my fault not from EL)

I will also submit a bug report, thanks!
