Hi, I installed the iceface turorial example and tested it, the prolem was found in below condition:
After the tomcat was started, I opened two IE window, in each window input the
URL:"http://localhost/ICEfacesTutorialExample/MyJsp.iface", then hit "Enter" for each IE at almost the same time(I did so to test the concurrent conditions), then the error infomation was outputed:

Failed to execute JSP lifecycle.

But if I firstly opened one IE, after it sucessfully loaded.then open another two IE and launch the same URL at the same time, this problem will not happen.

Is there any help to fix the probem at the first two concurrent sessions?
Thanks very much!
