If the user makes a selection I want to then go and retrieve the PDF via the persistent object's get/set methods that utilize the ValueHolder's interface methods getValue/setValue.ĭoes anyone have any idea why this exception is being thrown and anyway to fix it?

#First suggestion problem indirection code
When the code is executed a exception is thrown in the following method ServerSession(DatabaseSession).initializeDescriptors(Hashtable). The mapping seems find until I test the code. The column that contains the BLOB is not a primary key therefore in the "Table Reference" tab of the TopLink Workbench I use the database table's primary key for the "Source Field" and "Target Field".
