interceptors : The interceptors element specifies a customized stack of interceptors that will be used in place of the default stack. Currently this is only used when specified at the MBean level, but it could define a custom attribute or operation level interceptor stack in the future. The content of the interceptors element specifies a custom interceptor stack. If no interceptors element is specified the standard ModelMBean interceptors will be used. The standard interceptors are:

When specifying a custom interceptor stack you would typically include the standard interceptors along with your own unless you are replacing the corresponding standard interceptor.

Each interceptor element content value specifies the fully qualified class name of the interceptor implementation. The class must implement the org.jboss.mx.interceptor.Interceptor interface. The interceptor class must also have either a no-arg constructor, or a constructor that accepts a javax.management.MBeanInfo.

The interceptor elements may have any number of attributes that correspond to JavaBean style properties on the interceptor class implementation. For each interceptor element attribute specified, the interceptor class is queried for a matching setter method. The attribute value is converted to the true type of the interceptor class property using the java.beans.PropertyEditor associated with the type. It is an error to specify an attribute for which there is no setter or PropertyEditor.

persistence : The persistence element allows the specification of the persistPolicy, persistPeriod, persistLocation, and persistName persistence attributes suggested by the JMX specification. The persistence element attributes are:

currencyTimeLimit : The currencyTimeLimit element specifies the time in seconds that a cached value of an attribute remains valid. Its value attribute gives the time in seconds. A value of 0 indicates that an attribute value should always be retrieved from the MBean and never cached. A value of -1 indicates that a cache value is always valid.

display-name : The display-name element specifies the human friendly name of an item.

default : The default element specifies a default value to use when a field has not been set. Note that this value is not written to the MBean on startup as is the case with the jboss-service.xml attribute element content value. Rather, the default value is used only if there is no attribute accessor defined, and there is no value element defined.

value : The value element specifies a management attribute's current value. Unlike the default element, the value element is written through to the MBean on startup provided there is a setter method available.

persistence-manager : The persistence-manager element gives the name of a class to use as the persistence manager. The value attribute specifies the class name that supplies the org.jboss.mx.persistence.PersistenceManager interface implementation. The only implementation currently supplied by JBoss is the org.jboss.mx.persistence.ObjectStreamPersistenceManager which serializes the ModelMBeanInfo content to a file using Java serialization.

descriptor : The descriptor element specifies an arbitrary descriptor not known to JBoss. Its name attribute specifies the type of the descriptor and its value attribute specifies the descriptor value. The descriptor element allows for the attachment of arbitrary management metadata.

injection : The injection element describes an injection point for receiving information from the microkernel. Each injection point specifies the type and the set method to use to inject the information into the resource. The injection element supports type attributes:

setMethod : The setMethod attribute gives the name of the method used to set the injection value on the resource. The set method should accept values of the type corresponding to the injection point type.
