how big is portal/portlet session?

[prabhat.jha]

Hello :-)

If I add an attribute to Portlet Session as following:

PortletSession session = request.getPortletSession(true);
Integer data = new Integer(0);
session.setAttribute("my_data", data);

I then do serialization/deserialization to find the size of this object:

ByteArrayOutputStream bs = new ByteArrayOutputStream();
ObjectOutputStream os = new ObjectOutputStream(bs);
os.writeObject(seqNumber);
int sessionSize = bs.size();

Does it mean that Http Session size is value of sessionSize in above code snippet?

I have iterated through all the attributes in PortletSession (both app and portlet scope) and I see that there is nothing else in the session. There does not seem to be a way to get hold on HttpSession from Portlet and PortletSession is not serializable and rightly so, can I safely conclude based on above code that value of sessionSize is the value of size of HttpSession?

Answer is no. I modified ContentTypeInterceptor to spit out values in HttpSession since over there I have access to it and this is what I get:

Object org.jboss.portal.session.contexts
value is [/failover-portlet]

Object jboss.portlet.session.FailoverTestPortletInstance
value is org.jboss.portal.portlet.session.SubSession@1127dc0

Object portal.principalview_id
value is 0

Object portal.principal/default/FailoverTestPortletPage/FailoverTestPageWindow
value is org.jboss.portal.core.model.portal.navstate.WindowNavigationalState@17a1ad3

So, total session size will be sum of sizes of all these.
