i'm trying make project loads x3d files java , java display them, i'm using xj3d when run code, seem getting error. i've downloaded jars listed here. i've made library that's called 'xj3d' , in project properties, in libraries section, i've put xj3d library , in vm options, i've put -xmx450m -djava.library.path='c:\users\matt\downloads\xj3d-sai_2.0.0.jar' , code have in java is: 

package xj3dtest;  import java.awt.borderlayout; import java.awt.component; import java.awt.container; import static java.lang.boolean.true; import javax.swing.jframe; import org.web3d.x3d.sai.browser; import org.web3d.x3d.sai.browserfactory; import org.web3d.x3d.sai.x3dcomponent; import org.web3d.x3d.sai.x3dscene; import java.util.hashmap;  public class xj3dtest extends jframe {      public xj3dtest(string title) {          super(title);          setdefaultcloseoperation(jframe.exit_on_close);          // setup browser parameters         hashmap requestedparameters=new hashmap();         requestedparameters.put("antialiased",true);         requestedparameters.put("texturequality","medium");         requestedparameters.put("primitivequality","medium");         requestedparameters.put("xj3d_interfacetype","swing");         requestedparameters.put("xj3d_navbarshown",true);         requestedparameters.put("xj3d_navbarposition","top");         requestedparameters.put("xj3d_locationshown",true);         requestedparameters.put("xj3d_locationposition","top");         requestedparameters.put("xj3d_locationreadonly",true);         requestedparameters.put("xj3d_showconsole",true);         requestedparameters.put("xj3d_openbuttonshown",true);         requestedparameters.put("xj3d_reloadbuttonshown",true);         requestedparameters.put("xj3d_statusbarshown",true);         requestedparameters.put("xj3d_fpsshown",true);         requestedparameters.put("xj3d_contentdirectory","currentdirectory");         requestedparameters.put("xj3d_antialiasingquality","low");         requestedparameters.put("xj3d_culling_mode", "frustum");          system.setproperty("x3d.sai.factory.class", "org.web3d.ogl.browser.x3doglbrowserfactoryimpl");         x3dcomponent x3dcomponent = browserfactory.createx3dcomponent(requestedparameters);          browser browser = x3dcomponent.getbrowser();          component browsercomponent = (component)  x3dcomponent.getimplementation();          container cp = getcontentpane();         cp.setlayout(new borderlayout());         cp.add(browsercomponent, borderlayout.center);          x3dscene scene = browser.createx3dfromurl(new string[]   {"test.x3dv"});          browser.replaceworld(scene);     }      public static void main(string[] args) {         xj3dtest frame = new xj3dtest("xj3d test");         frame.setsize(640, 480);         frame.setlocationrelativeto(null);         frame.setvisible(true);     } }

and i've put test.x3dv file in project folder. test.x3dv code follows: 

#x3d v3.0 utf8  profile interactive  def ts timesensor {   cycleinterval 3   loop true }  def tg transform {   rotation 0 1 0 0   children shape {     geometry box {}     appearance appearance {       material def mat material {         diffusecolor 1 0 0       }     }   } }  def oi orientationinterpolator {   key [ 0 0.5 1 ]   keyvalue [      0 1 0 0      0 1 0 3.14      0 1 0 6.28   ] }  route ts.fraction_changed oi.set_fraction route oi.value_changed tg.rotation

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i
