DWR 3 with Spring3 ,DataSource is null and never gets initialized

I am new with DWT 3/Spring 3 & struggling for few days to get it working. I am using DWRServlet & dwr.xml for configuration & have a Class-DwrService directly accessed in my JSP.
Functionality is about 2 dependent dynamic dropdowns in JSP page based on ajax calls based on example (except i use dwr.xml)
http://www.codercorp.com/blog/spring...wr-spring.html

If i use mock data objects in my Service to populate data,DWR works fine but when i insert real DB calls,it gives me IllegalArgumentException:DataSource is null.
I tried using @Autowired & everything else but cannt figure out real problem.

I am copying configuration files here so that someone can help me finding where i am wrong.

------- DwrService ----
@Transactional
@Service
public class DwrService {

DataSource dataSource;

public List<FormType> getAllForms() throws ConsoleException {

SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(dataSource);
List<Form> formsList = new ArrayList<Form>();
ParameterizedRowMapper<Form> mapper = new ParameterizedRowMapper<Form>() {

@Override
public FormType mapRow(ResultSet rs, int rowNum) throws SQLException {

Form form = new Form();
form.setCode(rs.getString(2));
form.setDescription(rs.getString(3));

return form;
}

};
String sql = "select * from L_FORMS";
// SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(dataSource); //error here
return jdbcTemplate.query(sql, mapper, Collections.emptyMap());

}


public List<Entity> getEntitiesForForm(String formId) throws ConsoleException {

List<Entity> enList = new ArrayList<Entity>();
String sql = "select * from L_FORM_ENTITY where FORM_ID";
if (formId == null) {

} else
sql = sql.concat("='").concat(formId).concat("'");
SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(dataSource);//error here
ParameterizedRowMapper<Entity> mapper = new ParameterizedRowMapper<Entity>() {

@Override
public Entity mapRow(ResultSet rs, int rowNum) throws SQLException {

Entity entity = new Entity();
entity.setEntityId(rs.getString(1));
entity.setEntityName(rs.getString(2));

return entity;
}

};

return jdbcTemplate.query(sql, mapper, Collections.emptyMap());

}
}
-------Also my AbstractDataClass.---

@Repository("consoleDAO")
public class AbstractDataAccess implements IDataAccess {

private DataSource dataSource;
private Logger logger = Logger.getLogger(this.getClass());

@Autowired
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}

public DataSource getDataSource() {
return this.dataSource;
}

protected SimpleJdbcTemplate getSimpleJdbcTemplate() {
return new SimpleJdbcTemplate(dataSource);
}

protected SimpleJdbcCall getSimpleJdbcCall() {
return new SimpleJdbcCall(dataSource);
}

protected JdbcTemplate getJdbcTemplate() {
return new JdbcTemplate(dataSource);
}

}

I tried using this AbstractDataAccess but still my dataSource in DwrService is null allthe time.

I also tried refactoring the code and extracting out db calls to some separate DAO class (which complies with my design too) but then thinking about DWr conversion to javascript problems i kept single file.

Please suggest me what is going wrong here.
I can also paste mt JSP code but i think its java problem.

Use CODE tags when posting code / xml / stacktraces.

You should use Spring / DWR integration. Configure DWR through Spring so that you can use @RemoteProxy on your service beans, which you can easily wire up with your daos.

Use the procedure described here.
