org.hibernate.type.TextType and Oracle

We use Hibernate as a JPA provider and we have a class with a large object field marked with ``` @Lob @Type( type = "org.hibernate.type.TextType" ) private String someString; ``` The column is created as ``` SOMESTRING LONG() ``` This works flawlessly with PostgreSQL and MySQL. With Oracle when persisting the object ``` entityManager.persist( object ); ``` we get an `org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update` exception. Removing the `@Type( type = "org.hibernate.type.TextType" )` annotation will solve the problem with Oracle but introduces an encoding problem with PostgreSQL as described in Cannot store Euro-sign into LOB String property with Hibernate/PostgreSQL I would like to know how to define a large text field so that out program works on both PostgreSQL and Oracle. A pure JPA solution would be optimal but an Hibernate specific one will also do. Edit: The real exception: ``` java.sql.BatchUpdateException: ORA-22295: cannot bind more than 4000 bytes data to LOB and LONG columns in 1 statement ``` Now, the exception I missed explains the problem and in fact the object I am persisting has more than then the large string (at least one long DBID).
