I am a bit confused by what you actually want to do here. But I think you
should be using the service method instead of the doGet and doPost... the
following code will invoke both doGet and do Post
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{}
The public void service() can do both a doGet and a doPost. I hope this
helps.

Subject: Re: redirecting servlet page
Hi Deniz,
I think other people will have a better solution for your email, I just
did the following testing :-)
0
a in the sample code of a book -- "Mastering EJB and ..."
of Ed Roman -- [ISBN 0-471-33229-1], I find the following
line:
response.sendRedirect(response.encodeUrl("<sevlet name>"));
b I write two Servlet class -- servlet_ht and servlet_ht2
c I write a Java Application which communicates to
servlet_ht. ( I guess perhaps "Applet Servlet
Communication" is similar with "Application Servlet
Communication" )
d
* I use J2SE1.3 + Jsdk2.1 as Servlet engine
* I use J2SE1.3 to run my Java Application
1
[a] first I did a testing -- my Application [send + read] --
* in my Application, first I send a String to servlet_ht, so now
"doPost" of servlet_ht has been "invoked".
* then in "doPost" of servlet_ht, first I "read" this String, then
INSTEAD OF send back something to my Application
directly, I use the following:
response.sendRedirect(response.encodeUrl("/servlet/servlet_ht2"));
* now the "doGet" of servlet_ht2 has been "invoked", and I send
back
another String to my Application in "doGet" of servlet_ht2.
* then my Application read this String.
[b] I also did another kind of testing -- my Application [only read]
--
* in my Application, first I try to read a String from servlet_ht,
so
now
"doGet" of servlet_ht has been "invoked".
* then in "doGet" of servlet_ht, INSTEAD OF send back something to
my Application directly, I also use the following:
response.sendRedirect(response.encodeUrl("/servlet/servlet_ht2"));
* now the "doGet" of servlet_ht2 has been "invoked", and I send
back
another String to my Application in "doGet" of servlet_ht2.
* then my Application read this String.
[c] So from my testing [a] and [b], BOTH in "doGet" or "doPost"
of servlet_ht, I all can "sendRedirect" to servlet_ht2. This
is different from what you described in your email, please
try :-)

BTW, now I find a mistake in one of my emails about one month ago :-)
NOW I think in "Applet/Application Servlet Communication", we can
"invoke" both "doGet" and "doPost" with "URLConnection/HttpURLConnection",
but it depends on what we do in our Applet/Application --
[a] if we don't explicitly set "GET/POST" with
HttpURLConnection.setRequestMethod("GET/POST");
then:
* if we first "read", then "doGet" will be "invoked" ;
* if we first "send", then "doPost" will be "invoked" ;
[b] We also explicitly set "GET/POST" with
HttpURLConnection.setRequestMethod("GET/POST");

and I have a question:
How can I "invoke" the "doPost" of servlet_ht2 FROM servlet_ht
with the following ?
response.sendRedirect(response.encodeUrl("/servlet/servlet_ht2"));
Because now I find I only can invoke "doGet" of servlet_ht2 :-)
Thanks in advance!
