Subject Re: init() and destroy() in XSP
Date Fri, 01 Jun 2001 08:01:10 GMT
There are work-arounds though:

INIT:
Make a global variable, set it to null, inside your <xsp:page> block check
to see if it is null and do init stuff, then set it to something else.

DESTROY:
wouldn't  overloading void finalize() { ... } work here?
