stalling servlets/jsps with wait/notify?
I had an interview with a prospective client today who has problems with a current web application (written in lotus notes?). He knows from his present implementation that he can have no more than 5 simultaneous web clients accessing a certain resource that resides on a machine different from his tomcat server. Any additional clients must stall until the others are done. Hmmm Well on page 40 of Jason Hunter's Servlet programming book it explains that static variables are shared among multiple servlet instances. Hmmm... well JSPs are servlets, I wonder if I could create a static variable in a scriptlet (just for testing, of course) and use wait and notify to stall web client #6 until one of the other finish. Does anyone know if this would work? Siegfried __ Do you Yahoo!? Yahoo!

Why would the client stall in the first place ? If you can figure out that problem, the webapp could probably scale higher than 5 clients.

The present implementation uses some third party software overwhich we have no control. He knows from experimenting with the third party software that he does not want more than 5. --- Kwok Peng Tuck [EMAIL PROTECTED] wrote: Why would the client stall in the first place ?
