hi,
I spent almost 4 hrs to setup ibm vm (because I have to upgrade my glibc).
After that, I started to do the test again. This time, I got an exception
from jmeter and some error in my jserv's log. I tried to use jswdk instead
of jserv, I still got that exception(I forget the name). I didn't have any
problem when I used ie/ns to request that page and I didn't have any problem
when I used blackdown jdk1.1.7. Why? Is there anyone using IBM VM, jserv on
a linux box (suse 6.1)? It seems that IBM VM has some problems when a
servlet is requested simultaneously or intensely.
I am trying to ask some members of my team to use servlet, I need some
figures to show that servlet is better. I do think servlet is better. But
the fact is that they want to see. I cannot tell them if we use an expensive
machine, then servlet is better. How can I ask them to use servlet on a big
project when it doesn't handle a small project well.
I'm going to do another test. And I hope this time java will win.
rmi->servlet(apache, jserv)->client
php(apache)->php(apache)->client
I will post the results here when i finish.
