RE: [eclipselink-users] DatabaseException jdbc4.CommunicationsException

[MICHAEL.OBRIEN@xxxxxxxxxx]

Mathias,
	Hi, If you need to do something in JPA that does not have a property available - try a SessionCustomer and put the custome example java code you mentioned into this class.

	See the following JPA example where we had to change the lookupType on the JNDI connector to STRING_LOOKUP instead of Composite.

http://wiki.eclipse.org/EclipseLink/Examples/JPA/JBoss_Web_Tutorial#Create_J2EE_application


persistence.xml property:

	<property name="eclipselink.session.customizer" value="org.eclipse.persistence.example.unified.integration.JPAEclipseLinkSessionCustomizer"/>

Your Customizer:

	import org.eclipse.persistence.internal.sessions.factories.SessionCustomizer;
	public class JPAEclipseLinkSessionCustomizer implements SessionCustomizer {
		public void customize(Session session) throws Exception {

	thank you
	/michael

jdbc4.CommunicationsException


Hi,

how can I configure EclipseLink (with persistence.xml) to automatically
reconnect to the database after a CommunicationsException?

I've used autoReconnect=true at the JDBC connection string, but it does not
work.

Unfortunately, the EclipseLink documentation explains only how to set this
with the Workbench or Java API and not via persistence.xml. I don't use the
workbench.

Kind regards,
Mathias
