Hi, thank you for your answers. The Persistence I put was a quick modification of the one I had with OpenJPA, so that's why it didn't have the correct properties, the correct one is:
<?xml version="1.0" encoding="UTF-8" ?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd";> <persistence-unit name="VacationUnit"> <class>vacation.entities.Employee</class> <properties> <property name="openjpa.ConnectionURL" value="jdbc:derby://localhost:1527/Vacation" /> <property name="openjpa.ConnectionDriverName" value="org.apache.derby.jdbc.ClientDriver" /> <property name="openjpa.ConnectionUserName" value="VACATION" /> <property name="openjpa.Log" value="SQL=TRACE" /> </properties> </persistence-unit> </persistence> The errors are the ones I said before. I tried adding the provider and nothing. I tested a bit changing parameters and I figured out that it's like if it was not able to load the openjpa properties, like if it was not loading the openjpa library, and I have it added on my project's build path, I can even access to it from my Java class. It looks like it doesn't want to work for me :( -- View this message in context: http://n2.nabble.com/OpenJPA-not-connecting-the-database-tp4197138p4203077.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
