Attribute "value" must be declared for element type "property"???

[Angus McIntosh]

I don't understand where this exception comes from!

This is my hibernate.cfg.xml

  <?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="connection.url">
      jdbc:mysql://localhost/games?useUnicode=true&characterEncoding=UTF-8
    </property>
    <property name="connection.username">
      root
    </property>
    <property name="connection.password"></property>
    <property name="connection.driver_class">

    </property>
    <property name="dialect">

    </property>

    <property name="hibernate.connection.useUnicode">

    </property>
    <property name="hibernate.connection.characterEncoding">

    </property>
    
    <property name="show_sql">      true</property>
    <property name="format_sql">    true</property>
    <property name="hbm2ddl.auto"> create</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">              1</property>
    <property name="current_session_context_class">thread</property>
    <property name="hibernate.default_catalog">     games</property>

    <!-- Hibernate Search -->
 
    <property name="hibernate.search.default.directory_provider">
      org.hibernate.search.store.FSDirectoryProvider
    </property>
    <property name="hibernate.search.default.indexBase">
      ./data/indexes
    </property>

    <!-- List all the Annotated classes to use -->
    <mapping class="com.mycompany.Employee"    />
    <mapping class="com.mycompany.Description" />
    <mapping class="com.mycompany.games.Game"  />
    <mapping class="com.mycompany.games.Edit"  />
  </session-factory>
</hibernate-configuration>
  

and then I get this from my webapp when I try to persist:

But I don't see a "value" attribute anywhere to complain about!

Help me please!

[Kadle Rajesh]

Please validate your XML. You can validate it online at : http://tools.decisionsoft.com/schemaValidate/

[Paul Sturrock]

The XML looks valid. The DTD doesn't specify a value attribute for the property element (hence the error), however no property element in Angus's xml file has a value attribute. Which leads me to think that perhaps there is another invalid hibernate.cfg.xml file kicking around in your deployment maybe?

(In addition to the online tool you suggest you can just use IE to validate XML against schemas).

[Angus McIntosh]

I feel silly

I was editing the hibernate.cfg.xml in my sources directory and not the one in my classes directory.

Sorry for wasting your time!
