Re: Determine session size for Wicket 1.5
Hello,
Is there a good way to discover my serialised or about-to-be-serialised
session size without adding the debug bar to my page?
I currently use
@Override
protected void onAfterRender()
{
super.onAfterRender();
CloudSession ssnSession = (CloudSession)getSession();
long loSize = ssnSession.getSizeInBytes();
m_logger.log(Level.FINE, String.format("Session size = %,dB.", loSize));
}
in my WebPage subclass, but I suspect that this is the wrong place to
examine the session size.
My software environment is:
Web framework: Wicket 1.5.7
Web server system: Google App Engine for Java version 1.7.0
Java: 1.6.0_33; Java HotSpot(TM) Client VM 20.8-b03
Operating system: Microsoft Windows XP Home Edition version 2002 SP3
(version 5.1 running on x86; Cp1252; en_GB)

Thanks for the tip, Jochen.
I'm already doing that now, using Oracle's Java VisualVM....

Re: Determine session size for Wicket 1.5
Posted by Ian Marshall <Ia...@GMail.com>.
I don't think that I am getting the session size in the right place. Despite
my session sizes being logged as very small at ~1.7kB using the Google App
Engine (GAE) web development server, in GAE production I am getting session
sizes approaching 1MB (and attempting to breach this GAE-imposed limit of
1MB too).
I shall have to try and find somewhere else to get a meaningful session
size.

Re: Determine session size for Wicket 1.5
Posted by Ian Marshall <Ia...@GMail.com>.
Thanks Martin,
I could not find onDetach() but found detach() so I have done this in my
WebSession subclass:
@Override
public void detach()
{
long loSize = getSizeInBytes();
m_logger.log(Level.FINE, String.format("Session size = %,dB.", loSize));
super.detach();
}
This seems to be fine (my sessions seem very small at ~1.7kB - I must be
doing something wrong) except that this method can be called several times
as a result of one request.
Thanks again,
Ian

Override Session#onDetach() and do it before calling super.onDetach().
