Problem with dogListener from the Servlets JSP Book.

[Omar Perez]

Greetings Friends, God Bless,

Here is the thing I'm stuck with an error when I run the application on the server (Tomcat 7).

Is something related with my DD (I guess), so here is is my DD

I've tried changing the url mapping, but it doesn't work at all.

Not sure of the exact issue but are you sure you have deployed the correct version of the application?

<servlet-mapping> <servlet-name>ListenerTester</servlet-name> <url-pattern>/ListenTest.do</url-pattern> </servlet-mapping>

Doesn't seem to match the error message:

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> Tester.do in servlet mapping  
    at org.apache.catalina.core.StandardContext.addServletMapping(StandardContext.java:3155)

Thanks Nauman

For some reason whenever I run this application on the server is using the Beerv2 version and trying to call the logical name Tester.do, which is weird. I don't know what to do in this case.

[Nauman Hasan]

Can you uninstall the application. Restart the server (check to make sure no error) and then re-install the application?

Omar, please show us the relevant part of the view (e.g. jsp form action) where the servlet is called.
