S2Tapestry

次の3つのクラスで構成されます。
以前のまさたかさんのコードを最新のS2に対応させてます。

public class GlobalProxy {
    private Object global_;
    public GlobalProxy(Object global) {

        global_ = global;

    }

	

    public Object getGlobal() {

        return global_;

    }

}

public class GlobalProxyPropertyAccessor extends

    ObjectPropertyAccessor {
    public Object getProperty(Map cx, Object target, Object name)

        throws OgnlException {
        GlobalProxy proxy = (GlobalProxy) target;

        S2Container container =

            SingletonS2ContainerFactory.getContainer();

        String componentName = name.toString();

        if (container.hasComponentDef(componentName)) {

            return container.getComponent(componentName);

        } else {

            return super.getProperty(cx, proxy.getGlobal(), name);

        }

    }

}

public class S2Engine extends BaseEngine {
    static {

        OgnlRuntime.setPropertyAccessor(

            GlobalProxy.class,

            new GlobalProxyPropertyAccessor());

    }
    protected Object createGlobal(RequestContext context) {

        Object global = super.createGlobal(context);

        return new GlobalProxy(global);

    }

}
