Servlet calls java function

Question

hi
is there any way we can call a normal java function directly from a servlet? here's what i meant:
public void service(ServletRequest request, ServletResponse response)throws IOException{
some statements....
pw.println("<input type=button action='call javafunc(arg1,arg2)'>"); //something like this
int javafunc(arg1,arg2){
do some processing here..
if anyone does get what i'm trying to do, how do I actually get them working? because i know the code above won't work..
any help are greatly appreciated. thanks in advance.

Answer 1

If you are asking whether you can call a Java method from a servlet, sure you can. Servlets are written in Java themselves. Of course you can't have a method inside a method, if that's the problem you are referring to. Just put your javafunc method outside your service method.
However you can't have an action on the client side call that method. In fact an action on the client side can't use Java code at all. Javascript, yes, but not Java.
