How to use prepared statement by Application Module on ADF?

Question

Hello
i am using a prepared statement on the view side of my project,
this is my code, i'm not sure about using this code.
AppModuleGFTImpl am = (AppModuleGFTImpl) Configuration.createRootApplicationModule(amDef,config);
try {
ps =am.getDBTransaction().createPreparedStatement("Select * from XXXXXX where kullanici_id=? and sifre=?",0);
ps.setString(1, kullanici);
ps.setString(2, sifre);
rs = ps.executeQuery();
if (rs.next()) {
girebilir = true;
} else {
girebilir = false;
ps.close();
rs.close();
//am.getDBTransaction().closeTransaction(); ? I'm not Sure
//Configuration.releaseRootApplicationModule(am, true); ? I'm not Sure
Is it True? How we use this code on the project view side? Must we close Transaction, or release application Module.
thanks for interest.
sorry my english.

Hello, for the SP you can use something like this in your application module
  private static final String BULKSTAMMENN =
    "begin IVA_OWNER.IVA_UI_ALGEMEEN_PCK.USM_SNELLE_INVOER_GUI( P_RLE_ID => :1, P_AANTAL => :2, P_OJR_JAAR => :3, P_RAS_ID => :4, P_TOELICHTING => :5, P_SUCCES => :6 ); end;";
public void bulkStamen ( int rasId, int telerId, int jaar, int aantal, String toelichting ) {
    CallableStatement bulkStamenSP = null;
    try {
      bulkStamenSP = getDBTransaction().createCallableStatement( BULKSTAMMENN, 0 );
      bulkStamenSP.setInt( 1, telerId );
      bulkStamenSP.setInt( 2, aantal );
      bulkStamenSP.setInt( 3, jaar );
      bulkStamenSP.setInt( 4, rasId );
      bulkStamenSP.setString( 5, toelichting );
      bulkStamenSP.registerOutParameter( 6, Types.VARCHAR );
      bulkStamenSP.executeUpdate();
    } catch ( Exception e ) {
      log.warning( "Aanroep naar " + BULKSTAMMENN + " gefaald, " + e.getMessage() );
    } finally {
      if ( bulkStamenSP != null ) {
        try {
          bulkStamenSP.close();
        } catch ( Exception e ) {
          log.warning( e.getMessage() );
    log.info( "Stammen bulk uitgevoerd voor " + rasId + " " + telerId + " " + jaar + " " + aantal + " " +
              toelichting );
  }You can then drag this method onto your page or right into your task flow if your using JDev 11.
Also you can access it from a backing bean although the methods above are preferred
