Not setting up a provider in JPA doesn't add properties in persistence.xml -------------------------------------------------------------------------- Key: FORGE-1686 URL: https://issues.jboss.org/browse/FORGE-1686 Project: Forge Issue Type: Bug Components: Java EE Affects Versions: 2.2.0.Final Reporter: Antonio Goncalves Priority: Critical Fix For: 2.x Future If you create a project with a few entities and then scaffold a JSF front end without setting up jpa (command {{jpa-setup}}), the generated {{persistence.xml}} looks like this : {code} <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="test-persistence-unit" transaction-type="JTA"> <description>Forge Persistence Unit</description> <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> </persistence-unit> </persistence> {code} In the {{pom.xml}}, the Hibernate dependency has been added, so it's like Hibernate is the default.... but not Hibernate properties... so, unfortunattelly, the webapp doesn't work. Once deployed on JBoss it cannot create the tables... because there are some properties missing. If you run {{jpa-setup --provider Hibernate}}, then you have what you need : {code} <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="test-persistence-unit" transaction-type="JTA"> <description>Forge Persistence Unit</description> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="hibernate.hbm2ddl.auto" value="create-drop"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.transaction.flush_before_completion" value="true"/> <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> </properties> </persistence-unit> </persistence> {code} On one hand, Hibernate has been added to the pom, and on the other hand it hasn't beed added in the persistence.xml... So, by default, not executing {{jpa-setup}} should be equivalent as executing {{jpa-setup --provider Hibernate}}
