Summary: Exposed properties not serializable

Initial Comment:

JBoss 3.0.x, 3.2.0beta2, Solaris (concerns all 
platforms).

I try to read the ManagedConnectionFactoryProperties 
of a data source using MEJB (jsr77), but

Management management = getManagementMEJB();
...
management.getAttribute( 
dataSourceName, "ManagedConnectionFactoryPropertie
s" ); 

results in a "NotSerializableException", because neither 
the Crimson nor the Xerces implementation of 
org.w3c.dom.Element is serializable.

In general, all attributes exposed by MBeans should be 
serializable, otherwise they are not accessible through 
MEJB.

Exposing XML fragments in an MBean may be 
convenient for the programmer, but is of little use for the 
clients.

Regards
Georg

Ok. Understood.

This means, MEJB is only a second-class citizen in the JMX 
world.

Sorry, there is no requirement that mbean attributes be
serializable, however convenient it might be for you.

The particular problem you are having I hope to address soon
in jboss 4 by exposing the ManagedConnectionFactory itself
as an mbean: the mcf properties, all of which are
serializable, will appear as mbean attributes.
