org.mortbay.jetty.plus.annotation.Injection
Injection Represents the injection of a resource into a target (method or field). The injection is performed by doing an ENC lookup using the jndi name provided, and setting the object obtained on the target.

            // comments in the javaee_5.xsd file specify that the targetName is looked
            // for first as a java bean property, then if that fails, as a field
            try
            {
                Class clazz = getWebAppContext().loadClass(targetClassName);
                Injection injection = new Injection();
                injection.setTargetClass(clazz);
                injection.setJndiName(jndiName);
                injection.setTarget(clazz, targetName, valueClass);
                 _injections.add(injection);
            }
            catch (ClassNotFoundException e)
            {
                Log.warn("Couldn't load injection target class "+targetClassName);
