Thanks, The Proxy class is generated at compile time through whats known as Deferred Binding. Take a look here for more information about GWT.create(...): http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=DevGuideDeferredBinding Basically the GWT.create(...) method is used to run a bit of special code during the compilation which can generate additional code. It's also using in GWT localization, ImageBundles and a few other places. It's not a runtime method (it doesn't exist at runtime). Hope that helps.

Re: How to change the name of the host html page in project
Once compiled, take all the files inside the package-name folder and put them wherever you like. You can also change the host html page name to anything you want. If you change it in the source code, you will have to change it in any file that runs hosted mode. Just change 'MyProject.html' to the new name i.e. if there is no '.html' after the 'MyProject', don't change it because it is referring to something else - the actual project itself or maybe the prefix to the gwt.xml file. That is the problem with the project creator, although it makes things easy by asking for one name (e.g. MyProject) it names everything as MyProject - the main class file, the html file, the gwt.xml file, the launch files, and the project folder. If you go to my site and join up (and confirm your email address, just so people can't subscribe other people) for the free email course, the first day (which is sent immediately) there is a project you can download which has all the elements named differently. You can always unsubscribe immediately afterwards - the course mostly assumes you have Eclipse, so a lot of it might not be relevant for you.

Re: How to change the name of the host html page in project
Thanks for the reply. It sounds like you are suggesting a manual process. I'm looking for an auto process, something I can do in code/xml/html and it just works. I use maven to build a war, I don't have the option of manually moving files around. Is there a way I can code this in my gwt.xml and/or html, etc? Again, my goal here is to remove the package names from the URLs so the site URLs look more 'normal'. I.e. my index.html file (which is my welcome-file in my web.xml) points to com.mycompanyname.website.App/App.html. I don't want users to see all this package stuff. -Dave 2009/1/3 Ian Bambury ianbamb...@gmail.com Once compiled, take all the files inside the package-name folder and put them wherever you like.

Re: Who's Using GWT?
We're using GWT for the whole UI of Bionic Books, which is a small business accounting application: http://www.bionicbooks.com. Honestly I love GWT; Bionic Books has been written completely by 1 person (me) and I believe that there is no other technology that would have allowed me to build something of this sophistication in the relatively short time it took. In terms of requested features I can't really think of much; we, as I'm sure almost everyone has done, have written quite a lot of bespoke controls with richer functionality, e.g. we have our own combo boxes, multilevel dropdowns, extended ajax-ey list boxes with Loading..., etc and I think that there is possibly some ground to be gained in terms of richer controls. At some point we're going to review our codebase to see what we can contribute back.

Re: Getting data out of gwt grid
I did not see a reply but here is what I did. Sinceyou have the store,
ask for the record at the row index and then the field name. For
instance, I have a store with fields named property and value.
When I modify a value, I want the name of the property associated
with the value I changed. I already get the row and column from the
listener, eg.,
addEditorGridListener(new EditorGridListenerAdapter()
{public void onAfterEdit(GridPanel grid, Record record,
String field, Object newValue, Object oldValue,
int
rowIndex, int colIndex)
I then ask the store for the record at row (say 4), and then ask for
the value of the field property
store.getAt(4).getAsString(property)
This returns to me the name of the value I changed. Hope this helps.

Panel not clearing?
Hey, so right now I'm having this unusual problem with one of the
panels I made and I don't quite understand what's happening. Here's my
code:
bioText = new Panel();
bioText.setAutoScroll(true);
String sampleURL = img src = 'http://www.vella-gulf.navy.mil/Site
%20Images/under_construction.jpg' /;
bioText.setHtml(sampleURL);
ToolbarButton bioNew = new ToolbarButton(New Page);
bioNew.addListener(new ButtonListenerAdapter() {
public void onClick(Button button, EventObject e) {
bioText.clear();
}
});
Toolbar editBio = new Toolbar();
editBio.addButton(bioNew);
So basically I click the button on the toolbar and the panel is
supposed to clear but it doesn't. This is weird because within the
same class I do the same identical set of commands just using a
different toolbar and clearing a different panel and it works fine.
Any ideas?

Images not displaying after Upload
GWT: 1.5.2 Hi, I am having a problem displaying images after they have been uploaded to through my web application. My file upload screen has the file upload component, with a scaling mechanism sitting behind it, which all works perfectly. Once a file has been upload the upload service returns the URL of the created image back to the client, which I then use on the client side to add a new image object to my preview panel on the same page, however the image does not display. Ultimately, I get a string and build the following code to display the image on the preview panel using //imagefolder =images, which is the name of my base folder in build/ classes/com/mydev/web/ui/public //URL = returned URL from file upload for example 2/2008/11/30/1230664382652 //ImageSizes.SMALL = small //ImageSizes.IMAGETYPE = JPG //full URL equals images/2/2008/11/30/1230664382652small.JPG Image newImage = new Image(imageFolder+/+URL+ ImageSizes.SMALL +.+ImageSizes.IMAGETYPE); However once this displays on the screen the image does not appear but the empty box instead. What bothers me is that if I add the following code to my preview panel the image displays on a recompile: Image newImage = new Image(images/ 2/2008/11/30/1230664382652small.JPG); Ok so I am not left with logically trying to understand what is the difference/problem here and I been thinking along the lines of: 1. Input Streams from upload not closed when create image object first, however since I can open the image and see all details correctly in the folder structure I do not think this is the issue. 2. There may be a need to do a refresh on the panel, which I am currently trying to investigate. I have been investigating and debugging this for about 3 days now and have had no luck searching forums. I am hoping somebody here with a deeper understanding of how browsers/GWT handles image retrieval can point me in the right directions. Any help with this would be much appreciated.

GWT's tutorial discusses the trip from the server back to the client and not the other way around where I am unclear about. Do I need to set the header? Currently I set it to: builder.setHeader(Content-Type, application/x-www-form- urlencoded); However, this works fine as long as am sending key1=value1key2=values where I can retrieve variable via $_POST ['key1'] or $_POST['key2'] But I am not sure how to send a JSON string where it can be retrieved in a php page. I have tried sending myvar=MyJsonString but cannot retrieve in my php page. How should $_POST reference the JSON object? Any clarification would be much appreciated.

Re: GWT and applets
Looks like you're trying to compile your Applet code with GWT. That
will never work (not emulated; obviously you don't want to convert
your applet into Javascript, even if it were possible). Compile it
with plain Javac outside your GWT project or on the server side of
your project and then you include the class or jar file that defines
your applet in the public directory so that it is visible to your
AppletPanel class. Then you'll have to run your application in web
mode to test your applet.

Hi,
I'm probably missing something simple here, but I can't find the
answer elsewhere. I just want to display an applet in my GWT code.
OS: Windows XP
Java: JDK 1.6.0_10
Other: GWT, GWT-Ext 2.0.5
Here is the applet (obviously simplified for testing):
precodepackage foo.applet;
import javax.swing.JApplet;
import java.awt.Graphics;
public class HelloApplet extends JApplet
{
public void paint(Graphics g)
{
g.drawRect(0, 0,
getSize().width - 1,
getSize().height - 1);
g.drawString(Hello world!, 5, 15);
}}
/code/pre
Here is the code calling it:
precode
package foo.applet;
import com.google.gwt.user.client.ui.HTML;
import com.gwtext.client.widgets.Panel;
public class AppletPanel extends Panel
{
/code/pre
public AppletPanel()
{
HTML applet = new HTML();
applet.setHTML(applet name=\HelloApplet\ code=
\HelloApplet.class\ width=\300\ height=\300\ );
this.add(applet);
}
}
When I launch the app in hosted mode, the jvm crashes (filed incident
1425130 with Sun).
When I try to compile the GWT code for running in a browser, I get
this:
[ERROR] Errors in 'file:/C:/blah/applet/
HelloApplet.java'
[ERROR] Line 3: The import javax.swing cannot be
resolved
[ERROR] Line 4: The import java.awt cannot be resolved
[ERROR] Line 6: JApplet cannot be resolved to a type
[ERROR] Line 8: Graphics cannot be resolved to a type
[ERROR] Line 11: The method getSize() is undefined for
the type HelloApplet
[ERROR] Line 12: The method getSize() is undefined for
the type HelloApplet
Obviously I'm missing some applet library, but I've grepped through
all the jars in the jdk and tried including all of the ones that list
JApplet or awt (plugin.jar, resources.jar, rt.jar, deploy.jar,
javaws.jar).
Also, I'm pretty sure once I solve this problem there's another one
lurking right after it, but I'll save that for another question.
Thanks!

Re: Newbie Question on GWT/JSON
Whatever possessed you to send the application/x-www-form- urlencoded as mime type? JSON is nothing like form-encoded. That's like sending your HTML as image/jpeg just for kicks. Don't do that. JSON's mimetype is application/json (see [1] below). If you want to be nice, you should actually set that in the header (as follows: Content-type: application/json; encoding=UTF-8 - note that JSON is defined to be UTF-8 encoded, so you're just clarifying there, you can't pick your own encoding). And, yes, of course, in PHP you would have to get the entire request body, instead of letting PHP try to parse it as form data. Possibly PHP is presuming that the data IS form encoded when there is no header at all. Is file_get_contents(php://input); really the only feasible way to get the entire body in PHP? Oh, PHP. Every single time someone posts a code snippet written in PHP, my aesthetic sense blows its brains out in sheer despair. And this one is up there, which is really saying something. I think its a conspiracy by the zend folks to make the inner child of developers worldwide die a little inside every time they come in contact with it. Sadistic bastards.

First my disclaimer: the solution below may not be the proper one but it does work. Now on to the solution: On the GWT Client Side: JSONObject jObject = new JSONObject(); jObject .put(propA, new JSONString(valA)); jObject .put(... RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, YOUR_PHP_URL); builder.sendRequest(jObject.toString(), new YourReponseHandler()); Note that there is no setHeader. On the PHP side: Get the raw data instead of $_POST $jsonReq = file_get_contents(php://input); Decode the json request $request = json_decode($jsonReq); Cheers, Ian On Jan 3, 10:09 pm, Ian ikra...@gmail.com wrote: I am new to the Web application world; I am trying to encapsulate my set of data in a JSONObject, convert to string, and send it (async POST) to a PHP page using GWT's RequestBuilder.

Limiting text length in rich text area widget
Hi, I want to limit the text length inside the rich text area widget provided by GWT. But there is no implementation of a method like maxLength in this widget. I have tried implementing it using substring inside keyboardlistener but the problem is that I lose all the HTML formatting. Can anybody suggest a possible workaround.

[gwt-contrib] DOM event 1.6

[gwt-contrib] Am I going nuts? JavaScriptObject fields not accessible in JSNI.
I tried to do something fairly simple:
package testpackage;
public class MyClass {
@SuppressWarnings(unused)
private JavaScriptObject rawMap = JavaScriptObject.createObject();
private native void setSomething(String x) /*-{
th...@testpackage.client.myclass::rawMap[foo] = x;
}-*/;
private native String getSomething() /*-{
return th...@testpackage.client.myclass::rawMap[foo];
}-*/;
}
but it doesn't work - 'rawMap' doesn't exist according to GWT. (member
not found; expect subsequent errors). Yet when I replace my rawMap
with an identical line, except making rawMap an int, the error goes
away. I've worked around it with non-JSNI wrapper methods that pass
the JSO into and out of JSNI methods, but shouldn't the above code
just work?

I swear I looked for 30 seconds+ for typos and even copypasted the
package name, but, of course, I typoed the field name. Ignore this, my
bad.
