In the Manning book for SCWCD cert, authors say that the servlet mapping is not mandatory.If no servlet mapping is provided then they say that teh servlet could be accessed as
http://localhost:8080/APP_DIR/servlet/SERVLET_NAME
But Tomcat gives an error saying that it cannot find the resource.
Any ideas??
Thanks,
Arvind

Until now the invoker was enabled by default, but after 4.1.12 Tomcat the invoker is diabled by default.
Invoker servlet lets the Tomcat run the application servlet run without first making changes to /WEB-INF/web.xml file.
The class file for the servlet is dropped to the folder WEB-INF/classes and use http://host/servlet/servletname
To invoke the invoker servlet, uncomment the following lines in $install_dir/conf/web.xml (c:/Program files/Apache Group/Tomcat 4.1/conf/web.xml

<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern</servlet/*<url-pattern>
</servlet-mapping>

Am I wrong then in assuming that the specification leaves it up to the container to determine whether or not to allow default servlet mapping?
I know I can and should look this up but thought I'd ask here first.
