config Implicit Variable - Major Doubt

In Hanumant deshmukh's book [p-205]

initTest.jsp File :

Now it says that :
When JSP page initTest.jsp is accessed as a servlet, using the http://localhost:8080/chapter11/servlet/InitTestServlet it will work fine.

Ques 1: How can you access using Servet-Name?
Ques 2 : when i define proper servlet-mapping, then i can access it using url-pattern but when i print all the init ariables (not in above code) the output comes as :
fork : false xpoweredBy : false <Now proper init varaibles > ?
Why extra parms : fork and xpoweredBy ?

Did you try it actually?? It should have given you a 404...when you try to access using the servlet name instead of the url pattern...

You can a servlet directly without url-pattern with

urWebApp/servlet/servletName

Stein...are you sure?? I tried this and gave me 404...

I'm using a form action...I got my mistake...yes, you can access the servlet with its name...You are right stein...

tell me the exact URL that you are typing and also your servlet file name

Ok. . .great

Can you point out where did you get this from? Is it in the spces?

I am asking because in the exam we won't be tested on tomcat but on what the spec says.

As for Question 1., in the DD of the particular example you posted, there is an explicit servlet-mapping which happens to match the name of the servlet (prepended with the path /servlet).

Hi Sandeep,

Darren is right. In your DD you have this:

<servlet-mapping><servlet-name>InitTestServlet</servlet-name><url-pattern>/servlet/InitTestServlet</url-pattern> </servlet-mapping>

and you are using link <a href="http://localhost:8080/chapter11/<i rel="nofollow">servlet/InitTestServlet</i>" target="_blank">http://localhost:8080/chapter11/servlet/InitTestServlet to invoke the JSP. Thus you are not accessing your JSP with the value of <servlet-name> but with the name in <url-pattern>.

Thanks,

what i am trying to say is :

Suppose i have only defined <servlet> element in web.xml & not <servlet-mapping> as in :

then according to the book, i can access my JSP using :
http://localhost:8080/<web-app name>/InitTestServlet

Note: this is not working. Moreover how can i use a servlet-name to access JSP/servlet ?
