I developed jsp application on Tomcat, now I decided to change this app to Rails. I couldn''t do this at ones so in the beginning I want to serve in rails only some part of my system. What do you think about that? Is there anybody how has a practical experience in running Tomcat +Mongrel?

Your only chance of running Ruby on Rails apps in Tomcat is to use JRuby. I hear they are getting pretty close to having JRuby far enough along to run Rails applications. Tomcat is a Java application server. Ruby dosn''t run in the Java JVM unless your run JRuby. JRuby is a Java port of Ruby and is completly independent of the "real" Ruby (some refer to it as C Ruby, buy that''s typically only the Java guys that do that). I''ve never heard of anyone running Mogrel under Tomcat. I''m not sure if that''s even possible given that Mogrel is a Ruby based web server with a C componet. I doubt that it will run inside a Tomcat container at all.

Yes, you have right. But I was thinking about the similar solution as in Apache+Mongrel, And instead of Apache I want to use Tomcat. Is anybody using Rails on JRuby in real working project? Now I try to find some practical information about JRuby, I wonder if I need to change sth in my original rails code.

There''s folks running such setups in production right now.> Tomcat is a Java application server. Ruby dosn''t run in the Java JVM > unless your runJRuby.

Saying "C Ruby" helps clarify we''re talking about the implementation, not the language.> I''ve never heard of anyone running Mogrel under Tomcat.

But you wouldn''t run it inside Tomcat, you''d run it instead of Tomcat. Tomcat does just fine serving JRuby on Rails without Mongrel. - Charlie --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

JRuby is an interesting idea and does have lots of potential, but it does add another layer of interpretation which could alter your app''s behavior. Although there are some apps that have been successfully deployed with it, unless there is real assurance that JRuby reacts exactly like RealRuby®, I think the integration headache obviates the rapid development value that Rails/Ruby brings to the table. There is another option, which I did when I was doing J2EE/JSP work. Use Tomcat/JBoss as your app server, but use Apache for your front end static server. You can then use similar load balance techniques of Apache/Mongrel by using multiple workers (careful with this for sessions though). In the case of migrating from servlet/jsp to rails, you''d likely transition over some paths to Rails (think migrating servlets to controllers), so you have those managed by Apache forwarding to mod_jk (tomcat) vs mod_proxy_balancer(mongrel). Tomcat is a decent basic webserver, but is significantly slower than Apache at serving static pages/assets, just like Mongrel.
