GWT 1.7.1 don't show app in hosted mode (Jetty bug: FULL head)

[lain]

Two days ago I
- set up a last version of Eclipse (eclipse-jee-galileo, v 3.5)
- install plugins: App Engine SDK (1.2.5) and GWT SDK (gwt 1.7.1)
- add library GXT 2.0.1

Using this tools, I start developing web-app. First time it works
fine, but yesterday it unexpectedly fails!!! Hosted browser shows only
html-page and don't display any gwt-widgets!

______Error message is next:

"The server is running at http://localhost:51203/
10.10.2009 11:56:37 com.google.apphosting.utils.jetty.JettyLogger warn

______I try to fix this bug:
- clear cookies
- change IDE
- i even tried to enlarge the size of the header buffer and added the
following lines in my app-sourses:
import org.mortbay.jetty.Connector;
import org.mortbay.jetty.HttpConnection;
// in EntryPoint, onModuleLoad()
Connector c = HttpConnection.getCurrentConnection().getConnector();
c.setHeaderBufferSize(8*1024);

______All this methods don't work! I limit my ideas how to fix the bug
=(
Could you please help me?

What OS are you running on? 

My suspicion is that there is some sort of cookie problem (though I know that you tried to clear your cookies). Do you know if GXT sets some sort of cookie? Is your application code setting cookies? How did you try and clear the cookies?

[lain]

OS is Windows Vista (Business edition).

> Do you know if GXT sets some sort of

I don't work with cookies in code, my task can be made without low-
level programming.
In general, I did not expect that I will configure jetty... But... It
is demonstation of the law of leaky abstractions in action. =/

> How did you try and clear the cookies?

I clear folder "Cookies" in my OS.
Then I clear cookies, using GUI of browsers that installed in the OS.
Finally, I drop eclipse workspace (eclipse possibly saves wrong
cookies in workspace.. right?) and recreate it.

Could you tell me where I made a mistake? How can I fix this?

As an FYI, I think the default buffer size on Jetty 6 is 8k, so your current setting will not change anything. However, you should really not need to modify Jetty's parameters in this way. Do you have any idea as to why your request header could be more than 8k in size?

Can you compile your app, and then use FireFox with Firebug, and post your HTTP Request header (maybe attach it as a text file, if it is indeed 8k+).

> My suspicion is that there is some sort of cookie problem

You are completely right.

Now my application works fine without any configurations (because
cookies expiration date has come, I think), so this bug was really a
problem with cookies.
But this problem may occur again in the future. =(

If you know where the hosted browser stores cookies, could you tell
me? Probably, they were not stored in those directories, which I
cleaned.

Hm, I would have expected that to work. Can you verify that when this problem happens, you have large cookies in the directories that you tried to clear? 

I believe that the Vista cookies directory is:

C:\Users\ your user name\AppData\Roaming\Microsoft\Windows\Cookies

Hi,

Same here.

GXT does use cookies for storing theme related things.

See:
http://www.extjs.com/deploy/gxtdocs/com/extjs/gxt/ui/client/state/StateManager.html

It seems it is writing the cookies many times on the file
<user>@localhost[1].txt.

After deleting this file my application seems to work. I say "seems"
because there
is another error that looks like has nothing to do with the original
post.

I am running from Eclipse Galileo, on a Mac, GWT 1.7.1, GXT 2.0.1.

Does anyone know the name of the file that is keeping the cookies for
the hosted mode browser?

@Stephen: What platform are you on?

@Rodrigo: That sounds like a GXT-specific bug. Have you tried posting on their forum?

I am getting the same error when running in GWT hosted mode. The app
(GXT 2.0.1) runs fine on firefox. Where is this cookie file exactly,
I've looked around at the suggested location in this thread and cannot
find it?

It depends on your OS. What OS are you using?
