You can try using Uploadify from code.google.com/p/jqwicket/, which lets you
put event handlers on successful completion. You need to write a separate
servlet to handle upload though, but it's quite straightforward. One small
trick is overriding getEventHandler() so you can pass the javascript
generated to call the behaviour from other javascript components. The
example below uses a uuid to communicate between the upload form and the
servlet.
// ajax behaviour added to parent as bogus "onNever" event
handler
OnComplete onComplete = new OnComplete("onNever", ip, uuid);
wmc.add(onComplete);
wmc.add(new UploadifyWebMarkupContainer("upload", new
UploadifyOptions().auto(true).multi(false).scriptAccess("always").
script(getRequest().getRelativePathPrefixToContextRoot()
+ "upload?uuid=" + uuid).onCompleteEvent(onComplete.getEventHandler())));
...
/**
* AJAX behaviour fired when upload is ready
*/
public class OnComplete extends AjaxEventBehavior {
Picture picture;
String uuid;
public OnComplete(String event, Picture picture, String uuid) {
super(event);
this.picture = picture;
this.uuid = uuid;
}
public String getUuid() {
return uuid;
}
@Override
protected void onEvent(AjaxRequestTarget target) {
// servlet stores uploaded image
byte[] bytes = UploadifyServlet.getAndRemoveBytes(uuid);
if (bytes != null) {
PhotoUtil.handleImageUpload(bytes, picture);
}
target.addComponent(getComponent().getParent().getParent());
}
// need to be public
@Override
public CharSequence getEventHandler() {
return super.getEventHandler();
}
}
