Re: how to use global variable?
thanks to Bhushan and ss
but i had tried it also before mail u but i got some other errors
can u please try to solve this and mail me the code?
can i use static variables in recursion?
as my v will be increased in each call of fact(), can i take it static?
and what does it mean by static function and nonstatic function?
pls explain and if possible try this code and give me a running code
pleaassee
because i need it urgently as i want to use this recursion in my other
program.
ThankX in advance
Vaishali
inside static method u cannot call a non-static variable.

Re: how to use global variable?
Um... pardon my ignorance, but I'm failing to see the real problem here. You
defined a function, but the JSP page's out variable isn't available to it;
well, uh, why don't you pass the output stream to the function and use it?
%!
void myFunc(Writer out) {
out.println(This will show up in your page now. AMAZING.);
}
%
This isn't rocket science; just Java.

Re: how to use global variable?
Hi I have an application developed in Tomcat which is to be hosted in a production environment. But when hosted Tomcat crashes often giving Hot Spot Error. This is the error i get [jk_ajp13_worker.c (325)]: Error ajp13_process_callback - write failed [jk_ajp13_worker.c (203)]: connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [jk_ajp13_worker.c (621)]: Error reading request [jk_ajp13_worker.c (203)]: connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [jk_ajp13_worker.c (621)]: Error reading request [jk_connect.c (143)]: jk_open_socket, connect() failed errno = 61 [jk_ajp13_worker.c (173)]: In jk_endpoint_t::connect_to_tomcat, failed errno = 61 [jk_ajp13_worker.c (586)]: Error connecting to the Tomcat process. Anyone knows the reason for this. Or could anyone suggest better servers which could be reliable to be hosted in production?

Re: how to use global variable?
java.io
output and input classes are usually in java.io
you can use PrintWriter to be more specific with what JSPs use.

Re: how to use global variable?
No,
in % % will not be global
it will give undefined variable error while using them
u have to use %! % tag to declare global var

just declare these varibales within the tag % %
say after your head tag.

Re: how to use global variable?
You have declared the method as static and the variable is a nonstatic one. Either
declare the variable as static or make the method nonstatic.
