Constructors Summary
private JavaBeanConfigurator()
Creates a new instance of JavaBeanConfigurator
Methods Summary
public java.lang.ObjectconfigureBean(java.lang.Object bean, com.sun.enterprise.config.serverbeans.ElementProperty[] properties)
A Utility method to instantiate a class and set the properties.

         setProperties( bean, properties );
         return bean;
private final java.lang.reflect.Method[]getDeclaredMethods(java.lang.Class clz)
Utility method to get the declared fields.

        return (Method[]) AccessController.doPrivileged(new PrivilegedAction() {
       public Object run() {
                return clz.getDeclaredMethods();
            }

public static com.sun.enterprise.admin.selfmanagement.configuration.JavaBeanConfiguratorgetInstance()

        return singleton;
private voidsetProperties(java.lang.Object o, com.sun.enterprise.config.serverbeans.ElementProperty[] properties)
Utility method to set properties to the instantiated Object. _REVISIT_: We can just do java.beans.statement possibly
