| JndiJmx | | public class JndiJmx extends BaseModelMBean implements NotificationListener(Code) | | Link between JNDI and JMX. JNDI can be used for persistence ( it is
an API for storing hierarchical data and a perfect fit for that ), as
well as an alternate view of the MBean registry.
If this component is enabled, all MBeans will be registered in JNDI, and
all attributes that are set via JMX can be stored in a DirContext.
This acts as a "recorder" for creation of mbeans and attribute changes
done via JMX.
XXX How can we control ( filter ) which mbeans will be registere ? Or
attributes ?
XXX How can we get the beans and attributes loaded before jndijmx ?
The intended use:
- do whatever you want to start the application
- load JndiJmx as an mbean
- make changes via JMX. All changes are recorded
- you can use JndiJmx to save the changes in a Jndi context.
- you can use JndiJmx to load changes from a JndiContext and replay them.
The main benefit is that only changed attributes are saved, and the Jndi
layer can preserve most of the original structure of the config file. The
alternative is to override the config files with config info extracted
from the live objects - but it's very hard to save only what was actually
changed and preserve structure and comments.
