Subject How to bind jndi realm datasource so that my hibernate can find it can find it
Date Mon, 14 Jun 2010 11:54:44 GMT
Hello tomcats !! I learnt a lot since last discussion(problems at thejarbar.org) and am moving
on...

I now wish to configure the datasource used by the realm to also be used by hibernate....

Currently my server.xml looks as follows:


<?xml version='1.0' encoding='utf-8'?>

problem is that I am possibly under     the false impression that I am able to use the datasource
in hibernate as follows: 

Please note name being used

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD//EN"
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="connection.url">jdbc:mysql://localhost:3306/yucca123_thejarbar</property>
      <property name="hibernate.connection.datasource">java:comp/env/jdbc/auth"</property>
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
          <property name="current_session_context_class">thread</property>
         <mapping resource="org/bar/jar/model/UserRolesEntity.hbm.xml"/>
      <mapping resource="org/bar/jar/model/UsercommentsEntity.hbm.xml"/>
      <mapping resource="org/bar/jar/model/UsersEntity.hbm.xml"/>
      <!-- DB schema will be updated if needed -->
    <!-- <property name="hbm2ddl.auto">update</property> -->
  </session-factory>
</hibernate-configuration>

I get a decent explanation in exception:

avax.naming.NameNotFoundException: Name jdbc is not bound in this Context

ok, I can handle this but I was under the impression that name was global as being used in
engine node. So must I define a context.xml instead or is there a way to bind the jndi datasource
as so that it is found in this applications context? My understanding is false here and will
have a look at docs while I wait on reply. Bare in mind that I will be sharing datasource
and realm acroos more applications so  I have faith that server.xml is the correct place to
put this metadata.
