thanks for your email :-) and now I find mistake in my last email,
the following is my new understanding about Servlet(not JSP) with
jakarta-tomcat-4.0-b1 :
0 if we don't define any "named" servlet definition
in webapps/myapp/WEB-INF/web.xml, then we can invoke
MyServlet with the following way:
http://localhost:8080/myapp/servlet/MyServlet
it will invoke the "default/non-named" servlet definition
1 if we define the following in webapps/myapp/WEB-INF/web.xml:
...
<servlet-name>MyServlet_sn </servlet-name>
...
then we Also can invoke this servlet definition with this servlet-name:
http://localhost:8080/myapp/servlet/MyServlet_sn
2 if we also define a servlet-mapping:
<servlet-mapping>
<servlet-name>MyServlet_sn </servlet-name>
<url-pattern> /MyServlet_up</url-pattern>
</servlet-mapping>
then we Also can invoke this servlet definition with this url-pattern:
http://localhost:8080/myapp/MyServlet_up
and 1 and 2 will invoke the same "named" servlet definition whose
name is MyServlet_sn.
3 from a email in "List.this" ^_^ , I find:
if we directly use "MyServlet" as the servlet-name, and we invoke
with the following way:
http://localhost:8080/myapp/servlet/MyServlet
we will goto that "named" servlet definition whose name is
"MyServlet"-> we will Not goto that "default/non-named"
servlet definition.
hope the above is right, otherwise I need to correct my
"experience notebook" Again :-) or I need to use a pencial
instead of a pen? :-)
