Using Hibernate V3.0 rc1

I am getting this error:
org.hibernate.MappingException:
Unknown entity: com.nationsholding.xOps.common.model.Entity

when I try to run this code:
Code:

public EntityNations getEntityByID(String entityId){
      Session session = XopsHibernateUtil.getSession();
      List result = new ArrayList();
      EntityNations entity = null;
      try{
         entity = (EntityNations)session.get(Entity.class, entityId);
      
      }catch( HibernateException ex ){
         LOG.error(ex);
         throw new XOpsException( ex );
      }finally{
         NationsHibernateUtil.commitTransaction();
      }
return entity;
}


I dont think it is the mapping files because when I go to the hibernate console in Eclipse I am able to connect and get data from this mapping (Entity). Does anyone know what may be wrong. Please let me know if you need to see more code.

The mapping for Entity is not getting built into the SessionFactory. Look at your log where the SF is getting built

I am looking at the log and it looks like the entity is getting mapped, am I missing something else?

Ah, you overrode the entity-name in the mapping.

Either do:
Code:
entity = (EntityNations)session.get("entity", entityId);


Or, remove the entity-name attribute from that mapping

tried the
Code:
entity = (EntityNations)session.get("entity", entityId);



That didnt work still get the org.hibernate.MappingException: Unknown entity: entity error. Here is my mapping xml.


Code:
<class name="Entity" table="entity">
      <id name="entityId" column="entity_id">
           <generator class="assigned"/>
        </id>
        <property name="firstName" column="first_name" type="java.lang.String" />
        <property name="middleName" column="middle_name" type="java.lang.String" />
        <property name="lastName" column="last_name" type="java.lang.String"  not-null="true" />
        <property name="idEntityType" column="id_entity_type" type="java.lang.String"  not-null="true" />
        <property name="systemStatus" column="system_status" type="java.lang.Short"  not-null="true" />
        <property name="datetimeCreated" column="datetime_created" type="java.util.Date"  not-null="true" />
        <property name="datetimeModified" column="datetime_modified" type="java.util.Date"  not-null="true" />
        <property name="entityIdModified" column="entity_id_modified" type="java.lang.String"  not-null="true" />
        <property name="oldId" column="old_id" type="java.lang.Integer"  not-null="true" />
        <property name="entityOwnerId" column="entity_owner_id" type="java.lang.String" />
        <property name="locationId" column="location_id" type="java.lang.String" />
        <property name="delFullName" column="del_full_name" type="java.lang.String" />

So is it the <hibernate-mapping> surrounding this <class/> element which defines the java package? i.e.:
Code:
<hibernate-mapping package="com.nationsholding.xOps.common.model">
    <class name="Entity" ...>
    </class>
</hibernate-mapping>

Sorry missed that on the paste. Here it is
Code:
<hibernate-mapping package="com.nationsholding.xOps.common.model">

    <class name="Entity" table="entity">
      <id name="entityId" column="entity_id">
           <generator class="assigned"/>
        </id>
        <property name="firstName" column="first_name" type="java.lang.String" />
        <property name="middleName" column="middle_name" type="java.lang.String" />
        <property name="lastName" column="last_name" type="java.lang.String"  not-null="true" />
        <property name="idEntityType" column="id_entity_type" type="java.lang.String"  not-null="true" />
        <property name="systemStatus" column="system_status" type="java.lang.Short"  not-null="true" />
        <property name="datetimeCreated" column="datetime_created" type="java.util.Date"  not-null="true" />
        <property name="datetimeModified" column="datetime_modified" type="java.util.Date"  not-null="true" />
        <property name="entityIdModified" column="entity_id_modified" type="java.lang.String"  not-null="true" />
        <property name="oldId" column="old_id" type="java.lang.Integer"  not-null="true" />
        <property name="entityOwnerId" column="entity_owner_id" type="java.lang.String" />
        <property name="locationId" column="location_id" type="java.lang.String" />
        <property name="delFullName" column="del_full_name" type="java.lang.String" />
        <property name="idAddressTypePrimary" column="id_address_type_primary" type="java.lang.String" />
        <property name="idCommunicationTypePrimary" column="id_communication_type_primary" type="java.lang.String" />
    </class>
   
</hibernate-mapping>


My mapped class and the mapping reside in the same package com.nationsholding.xOps.common.model

Thanks for the help.

Post the stack trace for that exception, as well as the debug level log snippet for this operation. Also, a debug level log for the session-factory startup.

Are you using multiple session-factories by any chance?

I am running multiple session factories. I access the other before this one and that runs fine. I make sure I close the session on all my calls.

How do I change the debug log level for the session factory? In a previous post I pasted the debug log that I curently get. Here is the full debug code from start to error.

So make certain that you are not making that request on a session from the other session factory.

Hi

I am new to Hibernate. I am using Hibernate 3.3.1 with Jboss 5.

I copied hibernate configuration file and mapping file into ../server/sample/conf directory. And classes files located at ../server/sample/deploy/sample.war/WEB-INF/classes directory.

I am getting same exception(org.hibernate.MappingException: Unknown entity:) when i calling Hibernate from my application. Please help me to resolve this issue.

I tried to copy the mapping file to class file location, but no help.

Hibernate configuration file

Code:
<?xml version='1.0' encoding='utf-8'?>
<hibernate-configuration>
  <session-factory>
    <property name=“connection.datasource">java:sampleDB</property>
    <property name="connection.autocommit">false</property>
    <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
    <property name="show_sql">false</property>
    <property name="jdbc_use_streais_fbr_binary'>true</property>
    <property name="max_fetch_depth">3</property>
    <property name="cache.use_second_level_cache">False</property>
    <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
    <!-- Mapping files -->
    <mapping resource=“sampleLookupGenericData.hbm.xml"/>
  <session-factory>
</hibernate-configuration>


My hibernate mapping file

Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
