problem
i am facing a peculiar problem.
my application uses servlets and is placed on intranet my site.
only one of the machine in the network has some problem accesing the application.
once the user logs on to the application he gets an HTML page which has lot of links to different servlets.
in case of the problem machine..
the user reaches the HTML page but then gets a NULL POINTER exception when he clicks any other link
can anybody suggest possible causes for this

thank you ronny for ur prompt reply.
i havent gained an access to the system yet to incorporate the changes but now i feel confident about this working out.
another problem that i have is with the same application but in a different machine.
at a particular point in our application the business logic takes long time to get completed ( about 90 secs )
and this machine throws a NULL POINTER ( not again !!)
but again this happens with only this machine ( which is different from the previous machine )
what could be the problem ?
how do local machine configurations affect the perfomance of an application working on application server ?
i am aware that 90 secs of working time is too long..
but apart from that what could be the problems ?
thanx again in advance.

some permission you are missing perhaps, it could be that the he is trying to connect and fails, then retrying untill he gets there, but at that time he has a connection timed out and at client side, this could result in a nullpointer, because he doesn't know the connection is lost.

You should try and isolate the problem by comparing the configurations between a working machine and the problem machine. Check for any installed JDK's, ensure the browser version doesn't have any known problems and check how the user connects to the web, proxy servers and firewalls are a killer for web apps, although this shouldn't be an issue in your case as your just using Servlets.
