server side issue

Posted by rajesh nigam on August 17, 2000 at 6:13 PM

Hi,

I am working on a site whose line of business is Greeting Cards. We are using session bean(both state less and statefull ) as well as entity bean.We are using weblogic 4.5 on solaris.

I find a typical problem which recurs after 2-3 days and it is ( i solve it by restarting the server.. but this is not the solution!!!! ) :

When a customer is browsing and he clicks on search for a particular category of card .. he gets blank page.. while if I check it on my server console.. My search server is returning result.. but somehow it is not getting displayed... and it shows following error code:

java.lang.NullPointerException
