JSP_dood,

What exactly do you mean by "global variable"... there is no such thing as a "global" anything in java, and therefore a servlet and therefore a JSP page.

If you mean session scoped attributes google "servlet session scope"

[url=http://www.exampledepot.com/egs/javax.servlet/State.html]Saving Data in a Servlet[/url] looks like a good beginners guide to me.

Your app server should provide an admin interface where you can fine-tune the connection pool, for example, by specifying the number of connections in the pool.

Consult your server docs.

If by "global", you mean application scope, use the JSP application implicit object ( it's really an instance of ServletContext) to store data in that scope.

On lower-level scope, session scope has already been commented in this thread.

Or maybe you should start by studying the different scopes and their related implicit objects, to determine the one most suited for what you're trying to do.
