Hi!
 
Try this:
 
 
================ CODE EXAMPLE ================
// Generate a map containing your properties
HashMap<String, String> connnectionProperties = new HashMap<String, String>();
 
// Set your properties as you like:
connnectionProperties.put(PersistenceUnitProperties.JDBC_USER, "user");
connnectionProperties.put(PersistenceUnitProperties.JDBC_USER, "password");
 
// Pass the properties map to your EntityManager Factory
EntityManagerFactory emf = javax.persistence.Persistence.createEntityManagerFactory("GollumPU", connnectionProperties);
 
EntityManager em = emf.createEntityManager();
================ CODE EXAMPLE ================
 


Mit freundlichen Grüßen / Kind Regards

	Hello
	 
	I'm using this persistence.xml file and i want to change properties at runtime; How can I do it :
	 
	<?xml version="1.0" encoding="UTF-8"?>
	<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
	<persistence-unit name="EmployeeService" transaction-type="RESOURCE_LOCAL">
	<class>com.shemsit.model.Employee</class>
	<properties>
	<property name="toplink.jdbc.driver" value="com.mysql.jdbc.Driver"/>
	<property name="toplink.jdbc.url" value="jdbc:mysql://localhost:3306/testJPA"/>
	<property name="toplink.jdbc.user" value="root"/>
	<property name="toplink.jdbc.password" value="root"/>
	<!-- enable this property to see SQL and other logging -->
	<!-- property name="toplink.logging.level" value="FINE"/ -->
	<!--<property name="" value="app"/>-->
	</properties>
	</persistence-unit>
	</persistence>
