Btw, do I have to disable App Engine ? Actually My Project-Propertys->Google->App Engine-> Use Google App Engine is set. Do I have to configurate jdoconfig.xml?
When i use the following persistence.xml I dont get the exception anymore, buts its still not working :( Thats the output: Sep 26, 2012 7:13:11 PM org.hibernate.engine.jdbc.internal.JdbcServicesImpl configure WARN: HHH000342: Could not obtain connection to query metadata : Der Verbindungsversuch schlug fehl. Any ideas? :/ Adding i.e. <property name="hibernate.connection.pool_size">10</property> I get the ecxeption again. I had already tested the connection data with a jdbc connect, so they should be right. Thats the xml: <?xml version="1.0" encoding="UTF-8" ?> <persistence 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"; version="1.0"> <persistence-unit name="transactions-optional" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <!-- <class>de.mash.server.Worker</class> --> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/> <property name="hibernate.connection.url" value="jdbc:postgresql://127.0.0.1:5432/dev_mash"/> <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/> <property name="hibernate.connection.username" value="postgres"/> <property name="hibernate.connection.password" value="m4nu3l"/> </properties> </persistence-unit> </persistence> Am Mittwoch, 26.
