Hi again,

Thanks for this suggestion Sherry. It turns out that using EclipseLink in
combination with the ojdbc14.jar drivers defaults to using Oracle9Platform. In
this platform Double has a dependency on TimeStamp which is the reason for the
error I got. Using OraclePlatform by putting this in persistence.xl

<property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.oracle.OraclePlatform"/>

makes the error go away since in OraclePlatform there is no dependency of Double
on TimeStamp or any other class.

I hope this will help other developers debug their applications.


Greets, Wouter
