    Problems configuring Hibernate on JBoss

    Roberto López López Newbie

      Hi there!

      I'm configuring a struts project to access a mysql db through hibernate. It's my first time configuring hibernate in a project, so I have some problems.

      The most important, and the only I can't solve is this:

      - I have written my hibernate.cfg.xml with the config stuff.
      - I have written some table mappings (and their beans) and introduced them into hibernate.cfg.xml.
      - I have written a plugin to hook hibernate into struts, and declared it into struts-config.xml.

      I package the whole project (struts + hibernate) and deploy it to my JBoss 4.2.2 server. Then, I get the following output:

      As you can read on the last line, the factory isn't bound to any JNDI uri. Could anyone help me? Bellow are my config files.


      <?xml version='1.0' encoding='UTF-8'?>
       <!DOCTYPE hibernate-configuration PUBLIC
       "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

       <property name="connection.password">XXXX</property>

       <!-- thread is the short name for

       <property name="current_session_context_class">thread</property>
       <!-- this will show us all sql statements -->
       <property name="hibernate.show_sql">true</property>
       <!-- mapping files -->
       <mapping resource="/com/mmm/XXXXXXX/hibernate/mappings/Paises.hbm.xml"/>
       <mapping resource="/com/mmm/XXXXXXX/hibernate/mappings/Subcategorias.hbm.xml"/>
       <mapping resource="/com/mmm/XXXXXXX/hibernate/mappings/SubcategoriasUser.hbm.xml"/>


       <!-- ... -->
       <plug-in className="com.mmm.XXXXXXX.hibernate.plugin.HibernatePlugin">
       <set-property property="path" value="/WEB-INF/hibernate.cfg.xml"/>

      By the way, I can't understand hibernate-service.xml. I have read that I need to introduce the server datasource I want hibernate to use, but in hibernate.cfg.xml I have written the uri of mysql. Isn't it redundant? It's necessary to introduce the datasource in hibernate-service.xml??? Bellow its code:

       <mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=Hibernate">
       <attribute name="DatasourceName">java:/DefaultDS</attribute>
       <attribute name="Dialect">org.hibernate.dialect.MySQLDialect</attribute>
       <attribute name="SessionFactoryName">java:/hibernate/XXXXXXX</attribute>
       <attribute name="CacheProviderClass">
       <attribute name="Hbm2ddlAuto">create-drop</attribute>
       <attribute name="ShowSqlEnabled">true</attribute>

      The last question: do I need to separately package the hibernate application to access it from my struts webapp? I'm using ant to package and deploy my war, is there any ant task to package a har? I've searched on google and didn't found anything.

      Thank you very much in advance.
