[jboss-user] [JBoss Tools (users)] - How to configure Hibernate Console in a Maven project ?

[chawax]

Hi,

I work on a Maven project with JPA Hibernate implementation for persistence. I would like to make Hibernate console work with this project, but I encounter problems.

My project has EJB3 entity classes (with JPA annotations) and this persistence.xml file (all in build path and so in classpath)  :

<?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="t4Seam">
  |         <provider>org.hibernate.ejb.HibernatePersistence</provider>
  |         <jta-data-source>java:/jdbc/t4Seam</jta-data-source>
  |         <properties>
  |             <property name="hibernate.hbm2ddl.auto" value="update"/>
  |             <property name="hibernate.show_sql" value="false"/>
  |             <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
  |         </properties>
  |     </persistence-unit>
  | </persistence>

At runtime, database connection is configured with a datasource, so I added a hibernate.properties file to configure database connection for Hibernate console.

hibernate.connection.datasource=java:/jdbc/t4Seam
  | hibernate.connection.driver_class=com.mysql.jdbc.Driver
  | hibernate.connection.url=jdbc:mysql://localhost:3306/t4Seam
  | hibernate.connection.username=T4
  | hibernate.connection.password=T4
  | hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

I then created my Hibernate Console configuration with "JPA" type, selected my hibernate.properties file, configured the persistence unit as "t4Seam" and added MySQL drivers in the classpath.

For what I understood, this is all I need to do since it looks for required files (EJB3 entities, persistence.xml) in the classpath. But when I jump to the Hibernate configuration view and double click on my configuration, I have the following stack trace :

Can't find mapping file

Which mapping file is it talking about ? It is JPA, so it doesn't need mapping files, doesn't it ? Is there something special to do to make it work with JPA ?

Thanks in advance for your help ;)
