Chrome kills RAP Session [message #775671]

Hi,

This issue was previously reported as https://bugs.eclipse.org/bugs/show_bug.cgi?id=326123 with Chrome 7. I now have Chrome 16.0.912.75 for mac and the problem still persists. The session gets killed within one second of workbench display. A refresh results in a 500 error

SingletonManager already installed for session: 5nql......

Any insight would be appreciated

Thanks
Farooq

Hi,
could you provide a snippet to reproduce it? Which version of RAP are
you using?
Best,
Ivan

Hi,

do you happen to have javax.servlet 2.5 AND 3.0 both activated in your
launch configuration?

Hi Ivan,

The snippet would need 158 plugins to work. Would it help if I provide you with an access to the RAP application itself?

Thanks

Hi Farooq,
are you using a custom theme? Does it happens with RAP default or
business/fancy themes?
Probably there are two more related bugs:
331419: Session invalidation on Chrome 7 when coolbar button is pressed
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331419
301236: Background-image with rounded borders kills session in Chrome
https://bugs.eclipse.org/bugs/show_bug.cgi?id=301236
Best,
Ivan

Ok, that was just a wild guess, as I've seen this exception related to
duplicate servlet versions before.

At any rate, we need some sort of sample to reproduce the problem. Could
you try to reproduce it with a simple hello world application, may be by
adding some of the elements that you have in your UI?

Can you confirm that it only happens in Chrome? Did you also try it with
Firefox and Safari?

Ralf, thanks for the input and yes it happens only on chrome; FF, Safari and IE are all good. Today I was able to play around with a few things and although I cant exactly pin point the problem but to me its originating from the isEnabled() call of defaultHandlers (org.eclipse.core.commands.AbstractHandler) we use for commands in menus. I'm still looking ...

it happens to me several times today with starting Controls Demo in
Google Chrome 18.0.1025.11. I've opened a new bug for it:

Finally figured out the problem. Unlike IE or FF; Chrome every time and Safari on refresh calls "/favicon.ico" What this had to do with my code is I have an Index Servlet (mapped as "/") which simply does

If(user in session)
  redirectTo RAP app
else
  redirectTo login.jsp

I didn't realize a servlet mapped with "/" would also process /favicon.ico This causes the RAP app to be initialed twice within the context producing a session singleton manager already installed exception. I do not have a favicon.ico at root and I was expecting a 404. To work around this, I have now placed the code inside the following block

 if(req.getRequestURI().equals("/")){
	do the above
 } else
	resp.sendError(404);
