Modifying Persistence Connection Properties Dynamically

JPA 2.0 (Eclipse Link version)

We don't know which database to connect. In run-time, the connection factory (information) for the database we want to connect will be provided.
Sample information is as follows:

<persistence-unit name="PersistenceContextName" transaction-type="RESOURCE_LOCAL">
       <property name="eclipselink.jdbc.driver" value="com.mysql.jdbc.Driver"/>
       <property name="eclipselink.jdbc.url" value="jdbc:mysql://localhost:3306/dial_db"/>
       <property name="eclipselink.jdbc.user" value="root"/>
       <property name="eclipselink.jdbc.password" value="mysql"/>

Open in new window

What we want to do is to update connection properties dynamically (on-the-fly) without terminating Connection Factory.

How can we accomplish it? Any suggestions?

Thank you in advance,
