Re: application (with custom shell servlet) is not working at external tomcat
Hi Hasan,
The problem is most probably a 404 in tomcat.
Have a look at the headers (using something like the LiveHTTPHeaders
firefox plugin)
You'll probably find that the ...nocache.js file is not found.
If you packaged it into a war file or something, you'll see the whole
'edu.hacettepe.bote.ApiksApp' path has been renamed to
'edu.hacettepe.bote.apiksApp'.
That's the root of the problem.
The easiest solution would be to rename your module to something
starting with a *lowercase* letter.
Or just edit your module xml file...
Hope it helps

Hi all,
i've implemented a custom servlet (which is extending from GWTShellServlet)
only to response my main gwt page requests, otherwise, will call super.doGet

public class CustomShellServlet extends GWTShellServlet {

@Override

}
this is working at hosted mode but not working when i want to deploy my app
to an external tomcat instance. When i made my custom request (in fact,
which will generate the main gwt html file with some additional script
codes), it is entering my custom servlet, responding main application html
normally but i see an empty screen whose html source (view source) seems
normal - as below;

Re: application (with custom shell servlet) is not working at external tomcat
Thanks superkruger,
I've successfully deployed my module after app. Below are my notes;
- though my war file seems not renamed module path, i have renamed my module
name to lowercase as you suggested,
- created a new war by using tomcat war
builderhttp://code.google.com/p/gwt-examples/wiki/gwtTomcatWarBuilder
project,
- check the web.xml to include same servlet mappings with my module xml
Thanks again for your precious help...
Hasan...
