Please help meee.
I create a project named 'tesdb3' in eclipse. I create the PHP side to access the database, and made the output as JSON.. I create the userdata.php in folder war. then I compile tesdb3 project. Folder tesdb3 and the userdata.php in war moved in local server(I use WAMP). I put the PHP in folder tesdb3. This is the result from my localhost/phpmyadmin/tesdb3/userdata.php
[{"kode":"002","nama":"bambang gentolet"},{"kode":"012","nama":"Algiz"}]
From that result I think the PHP side was working good.Then I create UserData.java as JSNI overlay like this:
package com.tesdb3.client;
import com.google.gwt.core.client.JavaScriptObject;
class UserData extends JavaScriptObject{
protected UserData() {}
public final native String getKode() /*-{ return this.kode; }-*/;
public final native String getNama() /*-{ return this.nama; }-*/;
public final String getFullData() {
return getKode() + ":" + getNama();
}
}
Then Finally in the tesdb3.java:
public class Tesdb3 implements EntryPoint {
String url= "http://localhost/phpmyadmin/tesdb3/datauser.php";
private native JsArray<UserData> getuserdata(String json)
/*-{
return eval(json);
}-*/;
public void LoadData() throws RequestException{
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL.encode(url));
builder.sendRequest(null, new RequestCallback(){
@Override
public void onError(Request request, Throwable exception) {
Window.alert("error " + exception);
}
public void onResponseReceived(Request request,
Response response) {
Window.alert("betul" + response.getText());
//data(getuserdata(response.getText()));
}
});
}
public void data(JsArray<UserData> data){
for (int i = 0; i < data.length(); i++) {
String lkode =data.get(i).getKode();
String lname =data.get(i).getNama();
Label l = new Label(lkode+" "+lname);
tb.setWidget(i, 0, l);
}
RootPanel.get().add(new HTML("my data"));
RootPanel.get().add(tb);
}
public void onModuleLoad() {
try {
LoadData();
} catch (RequestException e) {
}
}
}
The result just showing string "my data". And the Window.alert(response.getText()) showing nothing. Whyy?
