hi vibha,
the objects will be eligible for garbagecollection if it is unreachable i.e.
no object references to that particular object. It is always better to put
your object references to null. You cannot be sure that setting the object
references to null, they will be garbage collected but they

hi celeste,
In our application , we use large number of JSP's say around 300.
Will there be a problem for Jrun to load all the servlets into the

the servlet if it is not referenced for longer time?

That doesn't FORCE garbage collection. Just suggests that if the GC would
like to run, it can.

From:
If implemented correctly the destroy() method can at most
cleanly forget all
references so as to make them garbage collectable. It
doesn't call garbage
collection.
System.gc() also does not necessarily run the garbage
collection right there when
called. This call only tells the garbage man "Hey
C actually occurs. Us mere mortals can merely make
requests. ;^)

hi campbell,
in java u have the destroy() method which when called will reclaim
the resources held by the object on which the method was invoked.
ex: if u call this method on a applet the thread gets killed.

No. You cannot force garbage collection. However, you can make
an object to become 'subject to' garbage collection by making it
'unreachable.' (assigning the reference varaible to null, for
example)
Because the garbage collector runs asynchronously to your program as a
separate thread,

Calling the gc method suggests that the Java Virtual Machine

currently occupy available for qu
