RE: Servlet-Mapping/Url-Pattern not recognized - Please - help ..
..
I would focus first on getting http://myhost:8080/myApp/doHello
to work. If it doesn't, http://www.myhost.com/myApp/doHello
isn't going to work either.
At this point it is usually good to check the log's to see
if there are any clues as to why the URL failed. There is
usually more there than what you can get from the response
returned to the browser. If necessary, add or increase the
debug="<level>" setting on various modules in the server.xml
to get more log output. To see if the servlet mapping is
or isn't matching the URL, add debug="1" to <SimpleMapper1 />.
Cheers,
Larry

Thanks Larry -
I never learn my lesson - the log files !!!!
An examination of the log files revealed the following error while trying
to parse my Deployment Descriptor:
> 2001-12-13 11:52:04 - Ctx(/franksTestApp) : Validating web.xml
> 2001-12-13 11:52:04 - Ctx(/franksTestApp) : web.xml: Error org.xml.sax.SAXParseException: Element "servlet" does not allow "servlet-mapping"
> here.
>
A close look at my web.xml revealed my DOCTYPE tag was slightly off:
I changed:
< DOCTYPE web-app
to:
<!DOCTYPE web-app
Restarted the server - and now both URLs WORK :)) - no parsing error ....
http://myhost:8080/myApp/doHello OK
http://www.myhost.com/myApp/doHello OK
Thanks Larry .......
Also ..... Thanks Andy for replying too .....
Cheers
Frank
I really appreciate the help ........
