Re: getSession(true) takes more than 20 seconds????
Well, I shouldn't reply just for thanks, but, the relief you gave me here compels me to do it!, since I'm trying to exhibit (and prove) the Java technology (and other good partnerships as linux) to some people here...

RE: getSession(true) AND SecureRandom
The best thing I can think of right now is create a servlet that you specify as a load-on-startup servlet. That servlet's init method then makes an http request to localhost for the correct webapp so that a session is generated.

Re: getSession(true) AND SecureRandom
Hi again, just a couple of things about this little headache of mine :-) : 1. -It seems that SecureRandom initializes at startup time since Tomcat 3.2.2 (currently beta :- ( ) 2.- So. what about that load-on-startup tag?? What are the possible values it may have? Thanks for the replies - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: getSession(true) AND SecureRandom
2.- So. what about that load-on-startup tag?? What are the possible values it may have? Those are part of the standard for servlet 2.2, and accordingly they are supposed to be set to a positive number, with the number indicating the relative order that the servlets should be loaded on startup.

RE: getSession(true)
It should only happen the first time you get a session. Its because initalizeing SecureRandom takes that long. If you search the archives there is a -D option that you can use to specify a different Random number generator that might work faster, but be careful. If someone can guess what the valid session ids are at any given time, you open yourself up to very large security attacks.

Re: getSession(true)
I haven't seen this sort of delay on 3.2.1 - what environment are you running tomcat in? My response time is around a second (as far as I can tell) - I'm using JDK 1.3.0 on Windows NT 4.0 on an Intel 550Mhz PIII laptop. -Thom Alfredo Solano Martinez wrote: Greetings, does anyone please know why Tomcat (3.2) takes 20 seconds to create a session?
