    <p>I have a bunch of service (ejb 3) classes that i want to unit test. In order to do so, i have added to their implementing classes an overloaded constructor which takes an EntityManager as an argument. The idea is that during my units tests i will create a both an EntityManager instance from a persistence unit specific for my unit tests, and an instance of my service class using the overloaded constructor. There, i pass the EntityManger created from my within my unit tests.</p> <p>My PU is configured as follows:</p> <pre><code>&lt;persistence-unit name="MyPU-junit" transaction-type="RESOURCE_LOCAL"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;non-jta-data-source/&gt; &lt;properties&gt; &lt;property name="hibernate.hbm2ddl.auto" value="update"/&gt; &lt;/properties&gt; &lt;/persistence-unit&gt; </code></pre> <p>And this is what i do to create my EntityManager in my unit test:</p> <pre><code> Map&lt;String, String&gt; config = new HashMap&lt;String, String&gt;(); config.put("connection.url", "jdbc:postgresql://localhost:5432/MyDb"); config.put("connection.username", "postgres"); config.put("connection.password", "admin12345_"); config.put("connection.driver_class", "org.postgresql.Driver"); config.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect"); config.put("hibernate.show_sql", "true"); emf = Persistence.createEntityManagerFactory("MyPU-junit", config); em = emf.createEntityManager(); </code></pre> <p>The problem is that i get this error:</p> <pre><code>SEVERE: could not complete schema update java.lang.UnsupportedOperationException: The user must supply a JDBC connection at org.hibernate.connection.UserSuppliedConnectionProvider.getConnection(UserSuppliedConnectionProvider.java:30) at org.hibernate.tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.prepare(SuppliedConnectionProviderConnectionHelper.java:27) at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:127) at org.hibernate.impl.SessionFactoryImpl.&lt;init&gt;(SessionFactoryImpl.java:314) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1294) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:859) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:126) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51) </code></pre> <p>I'm not sure it's related with the previous error but I'm also getting a bunch of warnings from the parser during initialization:</p> <pre><code>Failed to read schema document 'http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd' </code></pre> <p>Note that i did tried to run the same thing by putting the hibernate parameters in the persistence.xml file directly instead of programmatically.</p> <p>I am using netbeans 6.9.</p> <p>Any help is REALLY welcomed! I'm truly frustrated with this...</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
