I have a few questions out of curiosity :
I was on a website from a firm ordering material.
Then i encounter this error message :
Error 500 : MainServlet: unknown exception :java.lang NullPointerException
What does this error message mean ?
Does it mean there was Pointer with value "NULL" passed ?
Is this error happening at my browser (client ) or on the server side ?
Do i have a virus or some trojan ?
We have a firewall and a virusscanner that functions as a proxy.
Can it have anything to do with the firewall or the virus scanner ?
I never seen this error before...
Thank you in advance...
