| [eclipselink-dev] setProperty(Object,Value) of EM API |
|
Hello All: I am trying to implement 'setProperty(Object,Value)' method of EM API. I have few questions about the implementation : We have following properties that are supported properties in EM: JOIN_EXISTING_TRANSACTION PERSISTENCE_CONTEXT_REFERENCE_MODE PERSISTENCE_CONTEXT_CLOSE_ON_COMMIT PERSISTENCE_CONTEXT_PERSIST_ON_COMMIT PERSISTENCE_CONTEXT_FLUSH_MODE ORACLE_PROXY_TYPE EXCLUSIVE_CONNECTION_MODE EXCLUSIVE_CONNECTION_IS_LAZY JTA_DATASOURCE NON_JTA_DATASOURCE JDBC_DRIVER JDBC_URL JDBC_USER JDBC_PASSWORD CONNECTION_POLICY VALIDATE_EXISTENCE FLUSH_CLEAR_CACHE In the above, 'JDBC_DRIVER', 'JDBC_USER', 'JDBC_URL', 'JDBC_PASSWORD' cannot be changed once the connection is already made. According to the Spec, if the 'value' is not valid , it has to throw 'IllegalArgumentException.' I understand that we got to first check for properties that should not be changed using 'setProperty() ? What are those properties that should not be changed using 'setProperty()' And also, does changing any of the properties throw only 'IllegalArgumentException' ? Thank You Regards Darani |
