write to a jsp page where inside that jsp page i call the java bean. must i
pass it in as a variable or can i write psuedo code such as

as that is the default port for web services. there is no such thing as

or i am confused as well?

I have this problem where my applet will only work properly if I move the
mouse cursor over the applet. Once I do that all is ok but if I do not the
browser just hangs loading the applet, I just get a grey box. Does anyone
know why? im using java 1.4.1
mike
does anyone know if you can call instances to your own classes from java
applets?
ex.
class MyApplet extends Applet{
MyClass temp = new MyClass();
}
class MyClass {
MyClass()
}
for some reason when i do that everthing below my instantiation gets cut off
mike
i guess my question is in a java applet, can I import javabeans and use
them. I'm having trouble because I cannot make instances of the beans I
import.

hi,
im trying to implement this online game. currently my only solution to this
is having the browser auto refresh the database through my javabeans. what
are my alternatives? i only want to keep refreshing a bits of information,
not the whole jsp page. must i research into java applets?
for usebean, i know the bean expires for scope session when the browser is
closed. but for scope application, when does the bean expire? does it keep
running even after the person who called the bean exits his browser? if so,
how can the bean terminate itself in an application scope.
mike
except when the application
terminates. You can manipulate them using removeAttribute calls, etc.

If you are not running as a service you could always CTRL-C the window

If it is a jar file, you can put it in lib directory.
This is how mine is done. You will then need to restart your tomcat and it

Well, you should try search example online i.e. through google. EJB is a
standard and should work with any DBMS (usually ;) ). Once you find an
example and it should work on your choice of DBMS.
