Re: how can I add parameters in FileUpload
What i do is i add hidden inputs to the form i'm submitting along with
my picture, like so
private Hidden formTime = new Hidden();
private HorizontalPanel formHP=new HorizontalPanel();
public FormPanel uploadForm=new FormPanel();//form
formTime.setName(time);
formTime.setValue(+picTime);
formHP.add(formTime);
uploadForm.add(formHP);
then on the server.something along these lines.
public synchronized void doPost(HttpServletRequest request,
HttpServletResponse res)throws ServletException, IOException{
res.setContentType(text/html;charset=utf-8);
item=null;
//System.err.println(selectMstsq: +selectMstsq);
if(myWeb==null)myWeb=new PictureUploadServer();
File tempFolder =
(File)request.getSession().getServletContext().getAttribute(com.google.gwt.dev.shell.outdir);
//Check that we have a file upload request
boolean isMultipart =
ServletFileUpload.isMultipartContent(request);
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
items = new LinkedList();
try {
items = upload.parseRequest(request);
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
iter = items.iterator();
while (iter.hasNext()) {
item = (FileItem) iter.next();
String name = item.getFieldName();
if(name.compareTo(time) == 0){
picTime=Long.parseLong(item.getString());
}else if(name.startsWith(picture)){
uploadedStream = item.getInputStream();
/* This is to dump the upload to disk (create

AXIS I.P. camera
Hi
So as the title suggest i am having a a bit of an issue with I.P
cameras and GWT(More like an IE problem, with FireFox this issue is
not produced).
The issue is not the displaying of the video. The issue comes in when
i submit a form.
Let me just give you a bit of background:
I have 4 HTML objects in a Grid.
Each HTML object has a OBJECT tag.
Each OBJECT tag is essentially pointing to an I.P Camera.
I have a button which goes to the server and requests a snapshot from
the camera. That part works fine on both browsers.
The issue comes in, that in IE, as soon as that dialog pops up that
asks you what you want to do with the image, the classic, Save
Open and Cancel dialog, the video streams(So the OBJECT tags)
stop working, its as if the video freezes.
My server code is :
public void doGet(HttpServletRequest req, HttpServletResponse
response) throws IOException {
response.setContentType(image/jpg);
response.setHeader(Content-Disposition,attachment;
filename=Minez.jpg);
URL url = new URL(http://89.97.5.28/axis-cgi/jpg/image.cgi?
resolution=352x288);
URLConnection con = url.openConnection();
con.setUseCaches(false);
BufferedInputStream in = new
BufferedInputStream(con.getInputStream
());
ServletOutputStream out = response.getOutputStream();
byte b[] = new byte[24];
int count;
while((count=in.read(b)) != -1) {
out.write(b,0,count);
}
response.setContentLength(count);
out.flush();
out.close();
in.close();
}
The image returns fine but when the dialog pops up, it freezes the
video stream.
JSIO Class (for video):
public class CameraJSIO {
public static native String camera()/*-{
// Set the BaseURL to the URL of your camera
var BaseURL = http://89.97.5.28/;;
// DisplayWidth DisplayHeight specifies the displayed width
height of the image.
// You may change these numbers, the effect will be a stretched or a
shrunk image
var DisplayWidth = 352;
var DisplayHeight = 288;
var Bordersize = 0;
var objectID=player1;
// This is the path to the image generating file inside the camera
itself
var File = axis-cgi/mjpg/video.cgi?resolution=352x288 ;
// No changes required below this point
var output = ;
if ((navigator.appName == Microsoft Internet Explorer)
(navigator.platform != MacPPC) (navigator.platform != Mac68k))
{
// If Internet Explorer under Windows then use ActiveX
output ='div'
output += 'OBJECT ID='+objectID+' width='
output += DisplayWidth;
output += ' height=';
output += DisplayHeight;
output += 'border=0 ';
output += 'CLASSID=CLSID:DE625294-70E6-45ED-B895-CFFA13AEB044

output += 'to view live image streams in Microsoft Internet';

output += 'BR/OBJECT/div';
} else {
// If not IE for Windows use the browser itself to display
theDate = new Date();
output = 'IMG SRC=';
output += BaseURL;
output += File;
output += 'dummy=' + theDate.getTime().toString(10);
output += 'HEIGHT=';
output += DisplayHeight;
output += 'WIDTH=';

}
return output;

// document.Player.UIMode = MDConfig;
// document.Player.MotionConfigURL = /axis-cgi/operator/param.cgi?

// document.Player.MotionDataURL = /axis-cgi/motion/motiondata.cgi;
}-*/;
}
Normal client class that utilizes CameraJSIO.
Just have a form stick a button in it got to server to get
image..normal stuff.While the video is streaming obviously.
Any Ideas or comments are welcomed.

Re: multiple rpc calls to server
Hi A code snippet would be nice, so we can see where you're going wrong. Also put a Window.alert(), in your onFailure and onSuccess of your second call to see what you get. If it comes into the onFailure of your second call, there must be something wrong with the way you're calling the server side or your interfaces. If it comes in on your onSuccess, it must be a logic error, or something else pertaining to your client side code. If you make the first call successful and you call the second one the same way(logically) then there should be no issues. :) On Feb 6, 12:39 pm, ytbryan ytbr...@gmail.com wrote: Hi all, i know gwt don support synchronous call and i read it somwhere that there is actually don need to make rpc call synchronous. but i created an application with buttons like save data and display result that will communicate to server by fetching data or saving data. when the application starts, it will automatically display the first result with its first rpc call. but when i click the display second result's button... it doesn't work anymore. any subsequent rpc call after the first one don't work. what is wrong here? and what am i missing? can someone advice me? the usual rpc example online only show how to make one rpc call. is there a way to make multiple calls that do different task? thank you for your time in viewing this post. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hmmm..i just read that and it confused me What i meant to say is. Every time you send a photo to your servlet add a timestamp myPhoto + System.getCurrentTime() + . jpg; Then your are going to have to keep and array of timestamps for each photo. So when you load the photos you know which timestamp belongs to which photo. Just an idea.

The problem is calls to setImage(String imageURL) do not get updated

What am I doing wrong to set the image?

(X), And Then Start The Timer. The Timer Code You Pasted Looks Fine,
So You Can Just Use That. If You Are Concerned That Thirty Timers Are
Too Much To Handle, I Wouldn't Worry Too Much. However, If Practical
Testing Really Reveals That Is A Problem, You Can Do This. I'd Still
Go The Route Of A Custom Class, though. Basically, Create A Mapping Of
Event Times (The Time In Milliseconds When The Message Should
Disappear) And Store This In A TreeMap. Then, Set Up A Single Timer
That Waits Until The First Time In The Mapping Is 'Up'. The Code Sort
Of Writes Itself From There. If A New Timer Is Added, You Should Check
If It's Up Sooner Than The First Thing In The Map, And If So, Cancel
And Restart The Timer With The New Shorter Time.

Re: Only digits in TextBox: differences between Firefox and IE
Hi try this

KeyboardListener.KEY_DELETE){

((TextBox)sender).cancelKey();

In IE it works but in FF the Listeners is listen to the control-,
delete- and backspace- key too. I can't delete an character because
these keys are no digits.
How can I check if the keys are a control, delete or the backspace?

Re: ImageBundle combines my images
Hi
Are you using GWT 1.5?
Have you tried putting the images in the same level as the
MyImageBundle.java class?
so it would look like
@Resource(images/border_bottom.gif) (--or wherever your
MyImageBundle.java is)
public AbstractImagePrototype border_bottom();
i'm using 1.4 and it looks like this(just a snippet)
public interface Images extends ImageBundle {
/**
* @gwt.resource gogo.png
*/
AbstractImagePrototype gogo();
}
Other class that uses the Images class
public class Test{
Images images;//ImageBundle implementation.
Image gogoImage=null; //Normal GWT image object
public void createImages(){
images = (Images) GWT.create(Images.class);
gogoImage=images.gogo().createImage();
)
}
This might not help if you're using 1.5. I haven't tried using
ImageBundle in 1.5
HTH a little, :)

Re: novice question
Hey Shaul, Ian beat me to the punch.. Another way of looking at the same thing that Ian said is by thinking of it this way : Its a removing and adding of panels(and, or widgets). And each panel or layout container usually has its sets of widgets. AJAX is all about updating the components that need to be updated, caused by user actions. Thats my 2 cents, HTH :) On Oct 27, 8:26 am, Ian Bambury [EMAIL PROTECTED] wrote: Hi Shaul, Generally, GWT has only one html page. Everything is done by showing and hiding stuff. For example, you have a menu panel on the left and a display area on the right. When you click a menu item, your program swaps out the current display and swaps in the new one. The actual html file is the same one and is not reloaded, but you hide the 'home page' widget and show the 'about us' widget. If by 'two modules' you mean two entrypoint classes, then all the entrypoint classes get run when you start the application. If you mean something else, then yuo'll have to explain a bit more about what you have done.

Hi!
Im a beginer in GWT and i have to use Ext GWT.
But my problem is: i cant get any usefull tutorials or anything, to
get started with some of Ext GWT Widgets. Like the FormPanel.
As i cant register to the Ext GWT Forum, i give a try here, maybe
someone uses Ext GWT too and can help me.
My problem is pretty simple:
I create a FormPanel like this:
public class Formular implements EntryPoint {
private FormPanel formular ;
private Button createButton;
public void onModuleLoad() {
createButton = new Button(Ok);
form = new FormPanel();
TextFieldString name = new TextFieldString();
name.setFieldLabel(Nachname);
form.add(nachname);
form.addButton(createButton);
RootPanel.get(form).add(form);
}
}
Actually this form works. I can add things and stuff and hit the
button. But i cant wire any action listeners to this button. I just
dont get it, how this should be working? The button is not the same
button, as the GWT Button. The Ext GWT Button dont have any
addClickListener() method.
And so far i just cant find anything, to procede with the form.
This form just suck terribly.
I wanted to add a clickListener to the button and then start a method.
Symple as it is in GWT. In Ext GWT i just cant do anything.
Any hints, on how to work with Ext GWT Form Panels?

Hi hmmm...you should only see it once, as mentioned. 1) Are you sure you haven't added the listner twice? 2) Can you post you code up? 3) Are you sure you're not submitting twice? mon3y.

However, the form seems to get submitted twice as the Window.alert(The text box must not be empty); is executed twice. Any ideas as for why this happens?

Re: One Application, Multiple Modules (Developed Independently)
HI Well yes, what you have described in the beginning part can be done, so long as Panel A does not communicate with Panel B at compile time, or better said, as long as Panel A does not need/have any references to Panel B. Essentially you can have the following senario: 1) Framework is built and compiled(This should have the onModuleLoad() method). 2) Framework inherits Panel A like you would a library. (In Framework xml file something like this inherits name=com.google.gwt.user.User/ inherits name=path.to.PanelA.FirstClass/(This class should be treated as a EntryPoint Class, but should not implement EntryPoint) Then when you're ready to put in Panel B inherits name=path.to.PanelB.FirstClass/(This class should be treated as a EntryPoint Class, but should not implement EntryPoint) ) If you have any questions, don't hesitate HTH :) P.S : HTH---Hope That Helps.

That is close enough to describe my scenario. If that doesn't match your description, then... :) Basically, I realize our framework would need to provide some level of abstraction whereby add-ons would be dynamically defined/configured externally as menu items/actions/classes within some sort of site map, controller config file, or whatever you want to call it. The child classes are pretty much ignorant of one another at the source/class level, communicating through the framework interface or shared objects, etc. But they are hosted by a common UI framework.

So what you want to do is develop Panel A and Panel B independently of each other, and again for argument sakes, you release with panel A only and then the next release put on Panel B on your already existing framework? is this correct? And you want to know how to integrate Panel B on your next release? If i'm totally left field on this just reply with a smiley, :) If you want to do the above...yes it is possible and there are older threads on these forums that will lead you to what you need.

What I mean by developed independently is that a core UI framework would be built/distributed as a common infrastructure, and add-on components would be developed/distributed individually to integrate/run on this platform. Just like my application builds on the GWT UI classes, no? Yes, I understand this point, and yes this would work if you are only talking about compiling one component (or as many as source is available for) on top of the base framework module lbrary. But the idea breaks down after that in the same way that I cannot expect to build on top of one of your modules - because I do not have your source. I only have my source and the common library source. So, it is not an application in the traditional sense. Think more along the lines of Eclipse, for example (although I'm sure someone will point out it is a bad example). Plug-ins are developed for the Eclipse platform independently without much regard for one another. They are only interested in meeting the requirements of the framework. They are not compiled/distributed together as one big application. Correct? That's the idea here. If you're thinking like Eclipse then maybe you'll be stuck with a plug-in solution that's not the best fit for what you're actually doing. Maybe. We cannot control (or even anticipate) the development schedules of these plug-in components. They will probably need to be built and be targeted to a particular version of our framework, and updates will need to be sensitive to backwards compatibilty. But the resulting application will be any number of permutations of combined components all residing within the same core UI platform. It's made up of whatever pieces the customer decided to purchase (separately). The fact that you still have to package one of those permutations at some point in order to deploy it is the point I was making earlier. Permutations is not a problem for the GWT compiler, which will optimize each particular permutation to a better runtime than your plug-in approach could. No. The idea is not to package
