> Hi, > > I'm having a problem which I don't understand how it happens, nor do I know > how to continue isolating it. Let me try to explain the problem. > > I have a customer application running in IE. I also have a call center application, > an Windows MDC app with IE browser objects embedded. The two users > of these applications communicate with each other. > > In the call center application my JSP web page contains a frameset. This frameset > contains 2 frames, GUI and KERNEL as well as another frameset. The second > frameset contains 2 frames, POLLER and MESSAGE. All of the frames contains > a bean to an object A. Only these JSP pages has this object A reference, the server > do not. > > The POLLER frame checks with the server every 3 seconds of there are any new > messages to download. The response is a new POLLER page with potentially new > javascript included. > > The GUI page stays constant and is only unloded when the call center agent closes > the application. > > The KERNEL page stays loaded as long as the GUI page does. > > The MESSAGE page is for creating javascript message queues and stays loaded as > long as the GUI page does. > > The problem I have is that at a certain point, the POLLER gets a new reference to > object A. After that I start receiving nullpointers due to not properly initialized >variables. > > When I see this problem, I run Windows 2000, JDK 1.3.0.02, and ServletExec 3.1. > The interesting part is that when I run JBuilder 4.0 with Tomcat I do not see this > problem! > > My debugging tools are limited when using IIS (compared to JBuilder). How can I > trace or find out what's going on. > > I suspect that object A gets garbage collected. This would mean that somehow > the beans in the 4 pages looses its reference, or... > > Any help is greatly appreciated. > > Peter
