I am opening the discussion in [EMAIL PROTECTED], if you don't mind. I think there are others who may be interested in the topic.
jasper2 is in jakarta-tomcat-jasper. You'll need to build jakarta-tomcat-4.0 first, and then jasper2. It just drops the jar files into tomcat build area. Ignore jasper34 in that branch. Be warned that jasper2 is still under development, so it's quality is not release product quality yet. Also, it generates pretty much the same code as tomcat 4.x, for now; so expect comparable performance. Of course we'll need to change that! :-) It's great that you are doing performance evaluation for different versions of tomcat. Can your jstl run in tc3 and tc4 without change? Can we separated performance attributed to containers as opposed to those attributed to jasper? For those jasper performance, how can we identify the most profitable improvements that we should do? - kin-man > Date: Wed, 03 Apr 2002 07:29:32 -0500 > From: peter lin <[EMAIL PROTECTED]> > Subject: Jasper2 > To: Kin-Man Chung <[EMAIL PROTECTED]> > MIME-version: 1.0 > Content-transfer-encoding: 7bit > X-Accept-Language: en-US > > > hi kin-man, > > I was planning on checking your latest jasper2 today/tomorrow and > compare it against tc3.3 jasper and tc4.0.3 jasper. > > which branch should I check out to grab jasper 2.
