Hi fried . also i did not find anything regard to Tomcat 6 in tomcat web site but , Which services in java ee 5 you want to try in a tomcat instance ?
I want to be out of context Can i ask, why you do not like glassfish ? by the way , glassfish is not sun microsystem application server , it is opensource under CDDL in java.net . you can find it at : http://glassfish.dev.java.net
I was with tomcat and i was/am happy with it. but now I am using glassfish+netbeans in development of web /ejb applications. it's admin console is really superior ,monitoring features are really nice , performance as far as i can say is OK ... It is reference implemntatation of java ee 5 , it means that all components are available under glassfish umbrella , but Tomcat is web container. you can plug a JPA to it if you wanna use JPA... , but i think glassfish worth a look :-)
