Was wondering if someone can help me with an 'Injection of autowired dependencies failed':

Have you tried annotating InventoryManagerImpl as a @Repository?

[kezkez]

Put @Repository at InventoryManagerImpl but now getting jdbcTemplate problem:

Error creating bean with name 'InventoryManager' defined in file [C:\Program Files\springsource\vfabric-tc-server-developer-2.6.0.RELEASE\spring-insight-instance\wtpwebapps\SpringMVCExample2\WEB-INF\classes\springmvc\application\inventory\impl\I nventoryManagerImpl.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required

@Repository("InventoryManager")
public class InventoryManagerImpl extends JdbcDaoSupport implements InventoryManager {

    @Override
    public void addDvd(DVDDetails details) throws InvalidDvdIdException {
        // TODO Auto-generated method stub

    }

    @Override
    public DVDDetails getDetails(String dvdID) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public List<DVDInfo> getAll() {
        String sql = "SELECT DVD_TITLE_ID, TITLE FROM dvdtitle";
        final List<DVDInfo> result = new ArrayList<DVDInfo>();
        //obtain JdbcTemplate
        JdbcTemplate template = getJdbcTemplate();
        
        //Execute sql statemtn using RowCallbackHandler
        template.query(sql, new RowCallbackHandler() { public void processRow(ResultSet rs) throws SQLException { DVDInfo info = populate(rs);  result.add(info); } }  );
        return Collections.unmodifiableList(result);
    }

    private DVDInfo populate(ResultSet rs) throws SQLException {
        DVDInfo info = new DVDInfo();
        info.setID(rs.getString("DVD_TITLE_ID"));
        info.setTitle(rs.getString("TITLE"));
        
        return info;
    }
}
