Correction... ...the operands for the measurement are at RUNTIME scope...

This is particularly difficult in Java, since there is no reliable and invariable way to measure the size of an object. Interestingly, while trying to avoid work the other day, I stumbled onto this write up on the topic. Martin Roth asserts that the only way to do it in Java is to get the current memory footprint of the runtime before the object (HttpSession) is created and the footprint after the last object reference ( e.g. a session attribute) is added to it. The difference between these two values ~ yields to size of the object. This is, as you might guess, very unreliable, since the operands for the measurement are at application scope and it's not the only thing happening within the application. Also note that this measures only the size of the HttpSession instance and the object references it holds. It does not measure the physical size of the objects which are referenced by the session. http://martin.nobilitas.com/java/sizeof.html On 6/23/06, starki78 <[EMAIL PROTECTED]> wrote: > > Well I can remember having used session-size > tags that worked fine, > but after a while I came to the conclusion > that this is not so important. > http://www.servletsuite.com/servlets/ssizetag.htm > > Nice greetings > Starky > > ---------- Initial Header ----------- > > From : "Carl Smith" [EMAIL PROTECTED] > To : "Struts Users Mailing List" user@struts.apache.org > Cc : > Date : Thu, 22 Jun 2006 07:48:58 -0700 (PDT) > Subject : To get the session size > > > > > > > > > I am trying to get the session size of our J2EE Struts based, and > runing in WebSphere environment, application.
