failed to lazily initialize a collection of role hibernate3

[vani venkat]

hi
I have one to one mapping between three objects.
Job --> salesRole --> positionTemplate.

I am getting this "failed to lazily initialize a collection of role" error with hibernate 3. i tried to use lazy="false" to force hibernate to load eagerly.
still i get the same error when i try to access position template fields. Here are my hibernate mapping files.
job.hbm.xml

<hibernate-mapping package="com.callidus.ssln.server.bean">
    
    <class name="Job" table="CSS_Job">
        <id name="id" column="jobSeq">
            <generator class="native"/>
        </id>

       <property name="jobId"/>
       <property name="jobTitle"/>
       <property name="description"/>
       <property name="location"/>
       <property name="department"/>
       <property name="status"/>
       <property name="createDate"/>
       <property name="modifiedDate"/>
       
       <set name="candidates" table="CSS_CandidateJob">
        	<key column="jobSeq"/>
        	<many-to-many column="candidateSeq" class="Candidate"/>
    	</set>
    	<many-to-one name="salesRole" class="SalesRole" column="salesRoleSeq" unique="true" lazy="false" />
    </class>

</hibernate-mapping>

SalesRole.hbm.xml

<hibernate-mapping package="com.callidus.ssln.server.bean">
    
    <class name="SalesRole" table="CSS_SalesRole">
        <id name="id" column="salesRoleSeq">
            <generator class="native"/>
        </id>

       <property name="name"/>
       <property name="createDate"/>

		<many-to-one name="positionTemplate" class="PositionTemplate" column="templateSeq" unique="true" lazy="false" />    
    </class>

</hibernate-mapping>

position template.hbm.xml

<hibernate-mapping package="com.callidus.ssln.server.bean">
    
    <class name="PositionTemplate" table="CSS_PositionTemplate">
        <id name="id" column="templateSeq">
            <generator class="native"/>
        </id>

       <property name="name"/>
       <property name="requirements"/>
       <property name="responsibilities"/>
       <property name="yearsOfExperience"/>
       <property name="education"/>
       <property name="createDate"/>
       
    </class>

</hibernate-mapping>

Can some one please point out the problem. here is how i am loading Job object.

    @SuppressWarnings("unchecked")
    public ReviewResultsDTO getReviewResults(String jid) {
    	if(jid == null || "".equals(jid)){
    		System.out.println("error: "+ERROR_JID_NULL);
    		return null;
    	}
    	Long id = new Long(jid);
    	Session session = HibernateUtil.getSessionFactory().getCurrentSession();  
    	/*SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
        Session session = SessionFactoryUtils.getSession(sessionFactory, true);
        TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session)); */


        session.beginTransaction();
        Map arguments = new HashMap<String, Long>();
        arguments.put("jid", id);
        Job job = (Job)session.load(Job.class, id);
        //for time being not committing the transaction but, this should be removed once hibernate session is obtained using SessionFactoryUtils of spring
        //session.getTransaction().commit();
        
        /*TransactionSynchronizationManager.unbindResource(sessionFactory);
        SessionFactoryUtils.releaseSession(session, sessionFactory);*/
        //populate DTO to pass it to view.
        ReviewResultsDTO resultsDTO = new ReviewResultsDTO();
        if(job!=null)
        {
        	resultsDTO.setCandidates(job.getCandidates());
        	SalesRole salesRole = job.getSalesRole();
        	if(salesRole!=null){
        		resultsDTO.setSalesRole(salesRole.getName());
        		if(salesRole.getPositionTemplate()!=null){
        			resultsDTO.setEducation(salesRole.getPositionTemplate().getEducation());
        			resultsDTO.setResponsibilities(salesRole.getPositionTemplate().getResponsibilities());
        			resultsDTO.setYearsOfExperience(String.valueOf(salesRole.getPositionTemplate().getYearsOfExperience()));
        			resultsDTO.setRequirements(salesRole.getPositionTemplate().getRequirements());
        		}
        	}
        	resultsDTO.setPositionName(job.getJobTitle());
        	resultsDTO.setLocation(job.getLocation());
        	resultsDTO.setDescription(job.getDescription());
        }
		return resultsDTO;
	}

i tried to use http://today.java.net/pub/a/today/2005/10/11/testing-hibernate-mapping.html?page=last not to load beans lazily. the commented code in above method shows that. that gives the same problem. I have been trying to figure it out for the past two days. appreciate any kind of help regarding this.
thanks
