Example 1 with ClientHttpRequest

the class AbstractHttpOperationInvoker method getAttribute.

// TODO research the use of Jolokia instead

   * @param attributeName name of the attribute who's value will be fetched.
   * @return the value of the named attribute for the named resource (typically an MBean).
   * @throws MBeanAccessException if an MBean access error occurs.
