Re: Java version

[kf platypus]

I might be wrong but wouldn't you need at least a 1.2 jvm for the 
servlet/jsp architecture. I'm pretty sure others will agree. Give that a 
whirl. 1.3.1 is the latest fully supported JVM.

I should of know that JavaScript was available when you said applet. If 
thats the case images have an onLoad method which you can use to fire the 
timer in the fashion that he was speaking.

Re: measuring round trip time

[kf platypus]

I tried to do the same thing except the problem is that Java seems to use 
some sort of TCP/IP buffer so it's impossible to get accurate readings with 
that small amount of data. An ISAPI filter was my only solution. Even though 
afterwards in passing I did see something about disabling any buffering. So 
I don't know, see if you can find anything on that.

Regards!

RE: Tomcat does not Auto-reload.

[kf platypus]

just do something like:

if(request.getParameter("quit") == "1"){
//insert destroy code here
}

then just call http://yourdomain.com/servlet?quit=1

Re: Tomcat does not Auto-reload.

[kf platypus]

That's due in part to the servlet architectures caching mechanism. Typically 
we added a method to each servlet to destroy it. I don't know if there's a 
better method than that though as I know I would like to see one because 
they bith seem a bit ghetto.

Re: help me

[kf platypus]

Your JAVA_HOME environment variable should be set to c:\jdk1.3 and not 
c:\jdk1.3\bin and that should solve it.
