Hi,
There are around 100 objects stored in my application session.i want to know the size of Session object.
For this i perform the following code:
Enumeration enu=request.getSession().getAttributeNames();
int i=0;
               Object obj=null;
               while(enu.hasMoreElements())
String obj_name=(String)enu.nextElement();
                    long MemoryBefore=Runtime.getRuntime().freeMemory();
                    obj=new Object();
                    obj=(request.getSession().getAttribute(obj_name));
                    long MemoryAfter=Runtime.getRuntime().freeMemory();
                    obj.getClass().getName();
                    obj=null;
     System.out.prinltn(Session Attr Variable ::: "+obj_name +" and Size :"+(MemoryAfter-MemoryBefore));

For this i perform the following code:First, that code makes no sense. Second, I highly recommend using a [Java profiler|http://www.google.com/search?q=java+profiler] to measure your application's performance. It will be much easier than trying to cobble together code to do this on your own.
