Hi all,

I need help on implementing the blobstringtype.Earlier it was with blob ,now i have been asked to change it to blobstring type.
My config
Code:
  <bean id="nativeJdbcExtractor" class="org.springframework.jdbc.support.nativejdbc.C3P0NativeJdbcExtractor" />

    <bean id="oracleLobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler" lazy-init="true">
         <property name="nativeJdbcExtractor"> <ref local="nativeJdbcExtractor" />
   </property>
   </bean>
   <bean id="objCreateReqServiceImpl" class="com.ge.comfin.fleet.maintenance.requisition.service.CreateRequisitionServiceImpl">
      </bean>
<bean id="cdbSessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
      <property name="dataSource">
           <ref bean="cdbDataSource"/>
      </property>
      <property name="hibernateProperties">
           <ref bean="envHibernateProperties" />
      </property>   
       <property name="lobHandler"> <ref bean="oracleLobHandler"/> </property>
             <!--  OR mapping files. -->
      <property name="mappingResources">
         <ref bean="com.ge.comfin.fleet.maintenance.requisition.CdbHibernateMappings.HIBERNATE_MAPPINGS_CDB"/>
      </property>   
   </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager" class="org.springframework.transaction.jta.WebLogicJtaTransactionManager"> 
       <property name="transactionManagerName" value="javax.transaction.TransactionManager"/>
   </bean> 
   
   <bean id="myDAO" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> 
       <property name="transactionManager" ref="transactionManager"/> 
         <property name="target" ref="objCreateReqServiceImpl"/>
       <property name="transactionAttributes"> 
           <props> 
               <prop key="saveOrUpdateDownTimeToBlob">PROPAGATION_REQUIRED</prop> 
               <prop key="saveOrUpdateWADetailsToBlob">PROPAGATION_REQUIRED</prop> 
               <prop key="saveWAToBlob">PROPAGATION_REQUIRED</prop>
               <prop key="setAuthAmtZero">PROPAGATION_REQUIRED</prop>
               <prop key="updateLineItemStatus">PROPAGATION_REQUIRED</prop>
               <prop key="saveWaCommentDialog">PROPAGATION_REQUIRED</prop>
               <prop key="saveWAToOracleAnd3090">PROPAGATION_REQUIRED</prop>
           </props> 
       </property> 
   </bean>   


my pojo
Code:
public class WASessionData extends ModifiableObject implements Serializable {
...
private String sessionWA;
     
public String getSessionWA() {
   return sessionWA;
}
public void setSessionWA(String sessionWA) {
   this.sessionWA = sessionWA;
}


my hbm
Code:
<hibernate-mapping>
    <class name="com.ge.comfin.fleet.maintenance.requisition.orm.object.WASessionData" table="WA_SESSION_DATA">
<property name="sessionWA" type="org.springframework.orm.hibernate3.support.BlobStringType">
            <column name="SESSION_DATA" length="4000" precision="0" not-null="false"/>
        </property>   


and i have
Code:
@Transactional
    public WA saveOrUpdateWADetailsToBlob(WA wa,WADetails waDetails, int tempIdForSubDetails, HashMap<Object, Object> additionalWAInformation,String userId, boolean isExternalUser, AssetDetails assetDetails, MaintenanceContract maintenanceContract) throws Exception,
            ClassNotFoundException, SQLException {


for all the methods specified in config gile

and i am using hibernate version3.6.10.
Please let me know whether my config is right or not.
