bad formated mapping file

I'm new in the hibernate world and after having tried to use this framework, I still encounter some trouble using my mapping file, the file is like that :

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 package="com.genebio.toxico.compound">
    <class name="CompoundImpl" table="COMPOUND">
        <id name="id" column="COMPOUND_ID">
            <generator class="native"/>
        </id>
        <property name="cid" type="string" column="COMPOUND_CID"/>
        <property name="SMILE" type="string" column="COMPOUND_SMILE"/>
    </class>
</hibernate-mapping>

But when I launch my hibernate consol in eclipse, the consol report an error like [quote][/quote]org.hibernate.InvalidMappingException: Could not parse mapping document from file /home/yannmauron/Desktop/test/ToxicoMSJava2/src/java/com/genebio/toxico/compound/NewMapping.hbm.xml
org.hibernate.MappingException: invalid mapping
org.hibernate.MappingException: invalid mapping
org.xml.sax.SAXParseException: Element "class" requires additional elements.

Do you have an idea ?

Well, at first sight, your mapping seems correct to me. Could you give more logs? Use log4j for example and configure it to see org.hibernate in debug mode.

What's the full stacktrace of your error?

Right, in fact, yesterday, I have tried almost evry possibility and when I have restart my eclipse, the system worked...
But my next problem is the following :

Bonjour,

I have a config file like that :

Code:

<?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="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="hibernate.connection.url">jdbc:hsqldb:/home/yannmauron/toxico_db</property>
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
    
    
        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>


        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>
       
    </session-factory>
</hibernate-configuration>

a mapping file as :

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 package="com.genebio.toxico.compound">
    <class name="CompoundImpl" table="COMPOUND">
        <id name="id" type="int" column="COMPOUND_ID">
        </id>
        <property name="cid" type="string" column="COMPOUND_CID"/>
        <property name="SMILE" type="string" column="COMPOUND_SMILE"/>
        
    </class>
</hibernate-mapping>

But when I run my hibernate console, it says :

Code:

org.hibernate.MappingException: entity class not found: com.genebio.toxico.compound.CompoundImpl
  org.hibernate.MappingException: entity class not found: com.genebio.toxico.compound.CompoundImpl
  java.lang.ClassNotFoundException: com.genebio.toxico.compound.CompoundImpl

My file architecture is like that

src
->config.cfg.xml
->com.genebio.toxico.compound
->->CompoundImpl.java
->->CompoundImpl.hbm.xml

I cannot understant why it doesn't found the class, because the class exist... any idea ?

Hi

I think you are not configured that mapping file in hibernate.cfg.xml file
<hibernate-configuration>
<session-factory name="sessionFactory">
.........................................................
.....................................................................

<mapping resource="org/naru/mappings/Stud.hbm.xml"/>
</session-factory>
</hibernate-configuration>

You must mention the mapping file(hbm file)

(If this is helpful to please give the credits don't forget)
