jsr77 specifies the name for the mbean representing the ejb itself. Except for
the domain name part, its the same as the map part of the geronimo gbean name
for the ejb gbean. Jsr77 is not my strong point but I thought there were
supposed to be some statistics possibly available from the mbean for the ejb.
You might want to make your mbeans "children" of the jsr77 ejb mbean,
There's a method for making a child abstract name in geronimo like this (from
JSr77Naming.java in framework/modules/geronimo-kernel):
public AbstractName createChildName(AbstractName parentAbstractName,
Artifact artifact, String name, String type) {
if (name == null) {
throw new NullPointerException("No name supplied");
}
if (type == null) {
throw new NullPointerException("No type supplied");
}
Map nameMap = new HashMap(parentAbstractName.getName());
String parentType = (String) nameMap.remove(J2EE_TYPE);
String parentName = (String) nameMap.remove(J2EE_NAME);
if (parentType == null) {
throw new IllegalArgumentException("parent name must have a
j2eeType name component");
}
if (INVALID_GENERIC_PARENT_TYPE.equals(parentType)) {
throw new IllegalArgumentException("You can't create a child of a
generic typed gbean");
}
nameMap.put(parentType, parentName);
nameMap.put(J2EE_TYPE, type);
nameMap.put(J2EE_NAME, name);
return new AbstractName(artifact,
nameMap,
createObjectName(nameMap));
}
The crucial point here is the parent's last name component is name=foo, and
this has to be turned into parentType=foo,name=foo-child.
I'm not sure what will happen in geronimo when all the gbeans are exposed in
jmx and you add some more not backed by gbeans. However, this is something
we'll need to figure out.
