Do you mean you want to call doPost from doGet? And pass 200 values? A
servlet class can have both doPost and doGet methods. The method doPost
can be overloaded just like any other Java method:
doGet(HttpServletRequest req, HttpServletResponse res) {
Vector v = new Vector();
//put 200 values into come collection, perhaps a vector...
//but could be array, or Hashtable, or List, or Set or ...
//and call doPost
doPost(req, res, v);
}
//overloaded doPost
doPost(HttpServletRequest req, HttpServletResponse res, Vector vec) {
//send email using info from vec
}
Why do you specifically need to call the method doPost? You can name the
second method anything you want. Also, this other method probably
doesn't need access to any specific functionality from req or res, and
even if it did, you could put that information into the collection along
with all the other information. so now you have
sendEmail(Vector vec) {
//send email using info from vec
}
Finally, does this method really need to be a part of the servlet.
There's a school of thought that says servlet should just be
request/response, and other behavior belongs in other classes. So,
consider creating a class to handle email, and calling the methods of
that class from doGet.
doGet(.....) {
//fill vector vec with parms from req
MyMail m = new MyMail();
m.setParms(vec);
m.mail();
}
