Derby problem

Hi all,

I have a problem with my Derby database connexion :
------------------------------
Exception in thread "Timer-1" com.webobjects.eoaccess.EOGeneralAdaptorException: EvaluateExpression failed: <com.webobjects.jdbcadaptor.DerbyPlugIn$DerbyExpression: "INSERT INTO Entry(....)
Next exception:SQL State:23503 -- error code: 20000 -- msg: INSERT on table 'ENTRY' caused a violation of foreign key constraint 'ENTRY_USERPORTAL_FK' for key (15). The statement has been rolled back.
Next exception:SQL Warning:01J01 -- error code: 10000 -- msg: Database 'myDatabase' not created, connection made to existing database instead.

------------------------------


I don't know where this error come from.
I try to insert an object in the database, then another object. Then link these two objects, and finally saveChanges, but I get this exception.
If I insert an object, save changes. Then the other object, save changes. And finally link these objects, save changes, all work..


I think there is a problem with creation of my database, I don't really know what is the best way to do that, it's a little strange.
Or is it a problem with my editing context ? I use ERXEC.newEditingContext


Database config :
	Prototype : EOJDBCPrototypes
	Adaptor : JDBC
	URL = jdbc:derby:myDatabase;create=true
	Driver = org.apache.derby.jdbc.EmbeddedDriver

Thanks for your help
