Microsoft SQL Server and random JDBCAdaptor "failed to provide new primary keys for entity" error

Hi,


I have several WebObjects 5.3.3 / Java 1.5 applications in production since a long time. These applications are very stable, but sometimes (i.e. 0 to 10 times per week) I get IllegalStateException from the JDBCAdaptor adaptor claiming that is has failed to provide new primary key for an entity. The entity involved is not always the same, and this error seems to popup randomly.

I use the jDTS JDBC driver connected to a Microsoft SQL Server 2000 database using a custom JDBC adaptor plugin that inherits the default MicrosoftPlugIn one. This plugin is stable since a long time.

This is the typical stack trace:

java.lang.IllegalStateException: Adaptor com.webobjects.jdbcadaptor.JDBCAdaptor@2304c9 failed to provide new primary keys for entity 'Adresse'
at com.webobjects.eoaccess.EODatabaseContext.prepareForSaveWithCoordinator(EODatabaseContext.java:5885)
at com.webobjects.eocontrol.EOObjectStoreCoordinator.saveChangesInEditingContext(EOObjectStoreCoordinator.java:409)
at com.webobjects.eocontrol.EOEditingContext.saveChanges(EOEditingContext.java:3226)
...

Did somebody already have this kind of error? I would like to track down and fix this behavior, but I can't figure what's the cause. Did somebody have an explanation?


Kind regards,
