I was always thinking that shall we have a better way to handle all the available setting provided by the third-party modules? As we all know, usually, all the GBeans only delegate those important and popular settings, it is impossible for us to allow all the configurations could be done via GBean.  Let us take Tomcat as an example, maybe we shall give an interface to set those configurations that we do not provide now.

I think we could expose all the knobs on tomcat components in our gbeans but it might not be the most usable approach.  Basically the problem is that we have two component containers -- tomcat and geronimo -- both of which insist on creating all the components themselves.  While I tend to think that the main problem is that tomcat mixes the lifecycle and runtime code to intimately the only realistic way to get farther than we have now is to change geronimo so the components don't have to be created directly by the gbean infrastructure.

Thanks Ivan! I've examined the geronimo-tomcat-2.0.1.xsd and geronimo-tomcat-config-1.0.xsd, and am pretty sure many configurations are not available, like antiJARLocking, unloadDelay, etc. I understand that many of these settings might not work in Geronimo. Just try to see how we can play with the context.xml etc., which might be some good tips for migration from Tomcat.

Basically, Geronimo have created a GBean for each element in the server.xml, which means we should configure those settings via GBeans in the config.xml. But so far, I am sure the existing GBeans have not covered all the settings that tomcat provides. e.g. for server.xml, we have host gbean for the <HOST> element, actually, you could check the current setting in the geronimo\plugins\tomcat\tomcat6\src\main\plan\plan.xml. For the context.xml, a TomcatWebAppContext GBean will be created while deploying the web applications, and most configurations could be set in the geronimo-web.xml file.
Thanks for any comment, if any mistake is made, please point it out !

I just realize that I can put a context.xml in var/catalina/conf so that I can specify lots of Tomcat options there. I did a small experiment with the "workDir" param and it seems taking effect. Wondering whether this is supposed to work? Can I also put a server.xml there? Thanks!
