       Body:
Looks like I spoke to soon.  My last problem was a Groovy syntax problem.  In my Groovy script I provided something like the following...

pico.registerComponentImplementation("util", SomeRequestUtil.class)

Apparently, anything provided with ".class" in Groovy is seen as a plain java.lang.Class object.  All I had to do was remove the ".class" like this...

pico.registerComponentImplementation("util", SomeRequestUtil)

Everything works now, so, my fix was a good one!!!!  Patch coming up.

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
    }
}
