hi i created a second form which will let be choose a file and then
there is a button for uploading the file which communicates with a
servlet for the upload. Here are the 2 sources:
Why the file doesnt upload? Any ideas? Anyone to give me a working
example?
package faceRecognition.client;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.FileUpload;
import com.google.gwt.user.client.ui.FormHandler;
import com.google.gwt.user.client.ui.FormPanel;
import com.google.gwt.user.client.ui.FormSubmitCompleteEvent;
import com.google.gwt.user.client.ui.FormSubmitEvent;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.VerticalPanel;
@SuppressWarnings("deprecation")
public class FormUpload extends Composite{
final FormPanel form;
final VerticalPanel vPanel;
final FileUpload upload;
public FormUpload(String user) {
form = new FormPanel();
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
form.addStyleName("table-center");
form.addStyleName("demo-panel-padded");
form.setWidth("275px");
vPanel = new VerticalPanel();
upload = new FileUpload();
upload.setName("upload");
vPanel.add(upload);
vPanel.add(new HTML("<hr />"));
vPanel.add(new Button("Submit", new ClickHandler()
{
@Override
public void onClick(ClickEvent event) {
//form submit
}
}));
form.add(vPanel);
initWidget(vPanel);
form.setAction("/myfacerecognitionwa/upload");
form.addFormHandler(new FormHandler()
{
public void onSubmit(final FormSubmitEvent event)
{
Window.alert(event.toString());
}
public void onSubmitComplete(final
FormSubmitCompleteEvent event)
{
Window.alert(event.getResults());
}
});
}
}
