Multiple Datasource mapping problem

oguzyalcin.oguzhanyalcin.gazi.edu.tr Aug 3, 2009 8:17 AM

Hi all,
I'm trying to add an audit system to my application. I'm adding another Db for storing changes in it. The original DB is Taykos and the Log DB is taykos_log.I followed the way described in this link.

I've added the datasources:(project-ds.xml)

   <local-tx-datasource>
      <jndi-name>taykosDatasource</jndi-name>
      <connection-url>jdbc:mysql://localhost:3306/taykos</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>root</user-name>
      <password>111111</password>
   </local-tx-datasource>
   
   <local-tx-datasource>
      <jndi-name>taykosLogDatasource</jndi-name>
      <connection-url>jdbc:mysql://localhost:3306/taykos_log</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>root</user-name>
      <password>111111</password>
   </local-tx-datasource>

Added the persistence units:(persistence.xml)

<persistence-unit name="taykos" transaction-type="JTA">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:/taykosDatasource</jta-data-source>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
         <property name="hibernate.hbm2ddl.auto" value="update"/>
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/>
         <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
         
      </properties>
   </persistence-unit>
   
   <persistence-unit name="taykosLog" transaction-type="JTA">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:/taykosLogDatasource</jta-data-source>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
         <property name="hibernate.hbm2ddl.auto" value="update"/>
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/>
         <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
         
      </properties>
   </persistence-unit>

Made changes in components:(components.xml)

<factory name="dynamicEntityManager" scope="SESSION" value="entityManager"
          auto-create="true" />
     <persistence:managed-persistence-context
          auto-create="true" name="mainEntityManager" entity-manager-factory="#{entityManagerFactory}"
          persistence-unit-jndi-name="java:/taykosDatasource" />
     <persistence:managed-persistence-context
          auto-create="true" name="logEntityManager" entity-manager-factory="#{entityManagerFactoryLog}"
          persistence-unit-jndi-name="java:/taykosLogDatasource" />
     <persistence:entity-manager-factory
          name="entityManagerFactoryLog" persistence-unit-name="taykosLog" />
     <persistence:entity-manager-factory
          name="entityManagerFactory" persistence-unit-name="taykos" />

and added a seam component for managing different entityManagers:

@Name("entityManager")
@Scope(ScopeType.CONVERSATION)
public class DynamicEntityManager {
@Logger 
Log log;
     
     @Unwrap
     public EntityManager getDynamicEntityManager() {
          String dynamicEntityManager = (String)Contexts.getSessionContext().get("dynamicEntityManager");
          log.info("current value: "+dynamicEntityManager);
          if(dynamicEntityManager==null){
               Contexts.getSessionContext().set("dynamicEntityManager", "mainEntityManager");
               dynamicEntityManager="mainEntityManager";
          }
          EntityManager entityManager = (EntityManager)Component.getInstance(dynamicEntityManager);
          log.info("entitymanager is : " + entityManager==null?"null":"not null");
          return entityManager;
     }

}

when I try to get a resultlist on an EntityList object: this exception occurs:

Anybody having the same issue? Can anybody suggest me a way to success?
Thanks in advance.

You can try this,

Your persistence.xml file has transaction-type="JTA" so in your project-ds.xml file try using <xa-datasource> like

<xa-datasource>
<jndi-name>taykosDatasource</jndi-name>
<xa-datasource-property name="URL">jdbc:mysql://localhost:3306/taykos</xa-datasource-property>
<xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class>
<user-name>root</user-name>
<password>111111</password>
</xa-datasource>

<xa-datasource>
<jndi-name>taykosLogDatasource</jndi-name>
<xa-datasource-property name="URL">jdbc:mysql://localhost:3306/taykos_log</xa-datasource-property>
<xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class>
<user-name>root</user-name>
<password>111111</password>
</xa-datasource>

The error states that Program is not mapped, so my first question is if it works with a single database.

Have you looked at Envers for Hibernate for auditing, works great out-of-the-box, but I haven't tried it with two separate databases.

I have the same issue...

Did the suggestion work?

Hi!
I tried using the tag xa-datasource but Eclipse showed an error message about the structure of
XML document.
Here is an excerpt from the error message

The content of element type xa-datasource must match (jndi-name, use-java-context?, track-connection-by-tx, ...)

I used an example posted on the page of JBoss (
My Link)
and the error continues.

This is the complete contents of the file ds.xml
