Global Transactions or Ibatis's Automatic transactions

[ashok]

Hi

Does the daoManger.startTransaction(); created refers to the Global 
transactions or Ibatis  Automatic transactions?
What changes to be made if I need to use global transactions?
In my  DaoIntializer class  I create the daoManager as follows :

Reader reader = Resources.getResourceAsReader("com/example/config/dao.xml");
           daoManager = DaoManagerBuilder.buildDaoManager(reader);

and  dao.xml, sqlMapConfig.xml and web.xml contains the following enteries:

In my dao.xml :
<daoConfig>
   <context>
       <transactionManager type="SQLMAP">
           <property name="SqlMapConfigResource"
               value="com/example/config/sqlMapConfig.xml" />
       </transactionManager>

       <dao interface="com.example.ibatis.UserTableDao"
           implementation="com.example.ibatis.UserTableDaoImpl" />
   </context>
</daoConfig>

In my sqlMapConfig.xml

<sqlMapConfig>

   <settings cacheModelsEnabled="true" enhancementEnabled="true"
       lazyLoadingEnabled="true" errorTracingEnabled="false" 
maxRequests="32"
       maxSessions="10" maxTransactions="5" 
useStatementNamespaces="false" />

   <transactionManager type="EXTERNAL">
    <property name="UserTransaction" 
value="java:comp/env/UserTransaction"/>
     <property name="SetAutoCommitAllowed" value="false"/>
       <dataSource type="JNDI">
       <property name="DataSource" value="java:comp/env/jdbc/exampleDB" />
       </dataSource>

  <sqlMap resource="com/example/ibatis/sqlMap/UserTable.xml" />
</sqlMapConfig>



In my web.xml :

   <resource-ref>
       <description>Example DBConnection</description>
       <res-ref-name>jdbc/exampleDB</res-ref-name>
       <res-type>javax.sql.DataSource</res-type>
       <res-auth>Container</res-auth>
   </resource-ref>

   <resource-ref>
       <description>Example Transaction Manger</description>
       <res-ref-name>UserTransaction</res-ref-name>
       <res-type>javax.transaction.UserTransaction</res-type>
       <res-auth>Container</res-auth>
   </resource-ref>
