Re: Tomcat Alone or tomcat+IIS/Apache
We required IIS for a CGI ecommerce solution that was required. Plug and Pay I think is the company we bought it from. I came in late on the project and haven't had a lot of time to mess with it. Does Tomcat support CGI bins utalizing non-java technology?

Re: Tomcat Alone or tomcat+IIS/Apache
Dear Chuck, your mail is very informative. We r facing a similar issue in our organization :: Tomcat or Apache+tomcat. And the supporters of Apache+tomcat are arguing that as Apache/IIS can make use of native OS (windows inour case) libraries for thread management , memory mangement etc, they will fare well under high loads. And they argue that as Tomcat it self runs inside a JVM, which inturn is a single process all the threads etc wil be simulted ones (and not the native threads) and hence it will not scale up well under high loads. Is this argument a valid one or just a misunderstanding?? thanx for any kind of info in this regard.

Re: Tomcat Alone or tomcat+IIS/Apache
We had the same discussion a year ago, as we switched to tomcat 5 and was testing whether we do need apache in front of it. Actually the only advantage for this solution left were apache mods like url-rewriting - http://mydomain - http://mydomain/myapp/mypath - better for some search engines and so on. mod_gzip - now supported by tomcat directly. But this isn't worth installing an apache. The real problem with serving static content that tomcat has is the thread-model - one thread per connection is a bit messy if you have http 1.1 (keep-alives) on. But apache has the same issue. So if you have a log of static content to serve I'd strongly suggest you put a squid in front of your tomcats instead of apache (iis is a joke anyway). regards leon On 9/30/05, Mladen Turk [EMAIL PROTECTED] wrote: Peddireddy Srikanth wrote: And they argue that as Tomcat it self runs inside a JVM, which inturn is a single process all the threads etc wil be simulted ones (and not the native threads) and hence it will not scale up well under high loads.

Tomcat Alone or tomcat+IIS/Apache
I am just curious. I know that delivering static content with Apache/IIS is preferred. But does that matter if every single request has to go to Tomcat because the data is dynamic? Is there some caching that gets involved here? What is the benefit of Tomcat + Apache/IIS on major J2EE apps? Gregg
Re: Tomcat Alone or tomcat+IIS/Apache
Well I'm sure you can imagine that if all of your content is dynamic then layering tomcat behind Apache/IIS will only add latency/resources to your requests... nothing significant.. but maybe if your serving up a ton of requests it might be worthwhile to run tomcat standalone. -David Quoting Gregg D Bolinger [EMAIL PROTECTED]: I am just curious.

Convenience on using apache+tomcat vs tomcat alone
Hello All, I'm in the process of setting up a real-production server to serve a dynamic jsp driven website. And I'm facing the decision if using tomcat alone or apache+jk+tomcat. From what I've read on the ML I think that is best to use tomcat alone because I've got a completely dynamic web site, with just a few graphical images and not static html pages... so I think that the double step of apache that ask tomcat to give me a response is just a performance degradation... Are my thoughts right? or am I missing something? or maybe using JK2 instead of JK will give me benefetis even if the site is fully jsp driven?

RE: Convenience on using apache+tomcat vs tomcat alone
Howdy, I agree. Use tomcat standalone at least for now. It's the KISS principle. Any complications will have a negative effect.

Re: Convenience on using apache+tomcat vs tomcat alone
It still depends. If the graphics are large, or numerous then you may still win with Apache+jk. The only way to know for sure is to try it both ways. If you don't have the time/budget/patience for this, then my first guess would be that Tomcat-Standalone would be a good option.
