We want to migrate file persisted EJB timers to database persisted ones.

Has anyone had any experience with this ?

I was going to read in the XML files and then re-persist them.

This approach is fine until I try to decode the Base64 encoded string contained in the info tag.

The Base64 decoding works fine, however the resulting bytes don't seem to conform to the standard for a serialized object.

I assumed that what was contained in the info tag was just a Base64 encoded String generated from the bytes created by serializing the payload.

Any info / ideas on this would be welcome. The following is the code I'm using (pretty much standard for deserializing).

It results in an invalid header exception.

byte[] base64decodedBytes = Base64.getDecoder().decode( "TheStringContainedInTheInfoTag" );

try ( ObjectInputStream ois = new ObjectInputStream( new ByteArrayInputStream( base64decodedBytes ) ) ) {

    ScheduledArchiveJobTimerPayload payload = (ScheduledArchiveJobTimerPayload)ois.readObject();

}

Thanks
