    Comment:
I'm positive.  I built off the latest CVS and things work just fine if I provide a ContainerComposer class.  And keep in mind that the Groovy method is found just fine the first time, so it isn't like it isn't working at all.  It seems to me that it won't allow the compositionScope parameter to be different types in multiple calls.  I'm really not sure???

Anyway, here's a .war file you can test things on.  It has all required dependencies in WEB-INF/lib.  You be the judge as to whether they are up to date.  The web.xml is set up to use the "nanocontainer.groovy" context param with the goovy script.  That will fail upon request of index.jsp (actually upon attempted building of the request scope container in the servlet filter).  To see the app actually work, comment out the "nanocontainer.groovy" context param and uncomment the "org.nanocontainer.integrationkit.ContainerComposer" context param.  That one will work just fine proving that there is nothing wrong with the application itself, just the Groovy side of things.

Environment: servlet container, scripting of nanocontainer done with Groovy

Description:
When setting up the nanocontainer servlet in web.xml using the context-param "nanocontainer.groovy", it only seems to work for the first container that is configured, or, the first compositionScope.  If any other scope is provided such as a ServletRequest or HttpSession, it fails with the following message...

"Caused by: groovy.lang.MissingMethodException: No such method: buildContainer for class: nanocontainer with arguments: [org.picocontainer.defaults.DefaultPicoContainer-Le89R2mpRr8@public.gmane.org, org.apache.coyote.tomcat5.CoyoteRequestFacade@952905]"

I know it is working the for the first container (in the ServletContext compositionScope) because I print out the compositionScope as soon as the "buildContainer" method is entered and it says...

"compositionScope is: org.apache.catalina.core.ApplicationContextFacade-m6hyCi5e6VU@public.gmane.org"

Here is the script...

class DemoBuilder {
    buildContainer(parent, compositionScope) {
        System.out.println("compositionScope is: " + compositionScope);
        pico = new org.picocontainer.defaults.DefaultPicoContainer(parent)
        if (compositionScope instanceof javax.servlet.ServletRequest) {
            System.out.println("I got here to register a component in the servlet request scope!!!!")
            pico.registerComponentImplementation("util", SomeRequestUtil.class)
        }
        else if (compositionScope instanceof javax.servlet.http.HttpSession) {
            System.out.println("I got here to register a component in the servlet session scope!!!!")
            pico.registerComponentImplementation("counter", SomeCounter.class)
        }
        else if (compositionScope instanceof javax.servlet.ServletContext) {
            //nothing to do for now
        }
        else {
            //nothing to do for now
        }
        return pico
    }
}
