hi guys.
can anyone help me in getting unique client ids.
i 'am using hashcode to generate it.
but if i start two clients on the same JVM then the clientID remains same. well that doesnot create a problem in standalone mode.
but for n/w mode this will be a big problem.
even though it is a ridiculous thought of having two clinets running n/w access from same system.
point to note is that i'am generating unique ids on the client( i hope i'am doing proper)

There is a class in the JDK which called VMID. It should help you solve your problem.

Hi Siddharth,
Some more possibilities are UID and ObjID. I haven't got this one totally worked out either. So if you come up with something solid let me know.

hi,
In my design, i have a class names IDGenerator and only has one static method: generateId() and a static int variable. whenever this method is called, it will return a unique "id". let this class work in your server in which u want a unique id return to the client.
Hope it helps!
