Description

I hit a curious problem with using the <name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"> property with Oracle 10.2. The first time I ran my JPA application (it just populates and deletes rows in a single table), it ran fine, as the table did not previously exist on the Oracle DB server. Successive invocations of the test application fail with the following message:

<openjpa-1.2.1-SNAPSHOT-r422266:686069 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: ORA-00955: name is already used by an existing object

I switched databases to DB2, and this problem did not occur. So it seems that the mapping tool is not able to accommodate existing tables with Oracle – it bails out immediately, even if the existing table's schema matches the entity's structure.
