Method Detail

locateMBeanServer

public static MBeanServer locateMBeanServer()
                                     throws MBeanServerNotFoundException

Attempt to find a locally running MBeanServer. Fails if no MBeanServer can be found, or if more than one is found.

Returns:

the MBeanServer if found

Throws:

MBeanServerNotFoundException - if no MBeanServer is found, or more than one is found

parameterInfoToTypes

public static Class[] parameterInfoToTypes(MBeanParameterInfo[] paramInfo)
                                    throws ClassNotFoundException

Convert an array of MBeanParameterInfo into an array of Class instances corresponding to the parameters.

Throws:

ClassNotFoundException

getMethodSignature

public static String[] getMethodSignature(Method method)

Create a String[] representing the signature of a method. Each element in the array is the fully qualified class name of the corresponding argument in the methods signature.

getAttributeName

public static String getAttributeName(PropertyDescriptor property,
                                      boolean useStrictCasing)

Return the JMX attribute name to use for the given JavaBeans property.

When using strict casing, a JavaBean property with a getter method such as getFoo() translates to an attribute called Foo. With strict casing disabled, getFoo() would translate to just foo.

Parameters:

property - the JavaBeans property descriptor

useStrictCasing - whether to use strict casing

Returns:

the JMX attribute name to use

isMBean

public static boolean isMBean(Class beanClass)

Check whether the supplied Class is a valid MBean resource.

Parameters:

beanClass - the class of the bean to test
