JMX implementation does not support More than one JSPWiki instance
------------------------------------------------------------------
Key: JSPWIKI-452
URL: https://issues.apache.org/jira/browse/JSPWIKI-452
Project: JSPWiki
Issue Type: Bug
Components: Core & storage
Affects Versions: 3.0
Environment: JSPWiki 3.0
Reporter: Harry Metske
Assignee: Harry Metske
Priority: Minor
The current JMX implementation does not handle multiple JSPWiki instances per
JVM very well.
This is true for both the new LoggerMBeans as for the other Admin type MBeans.
The problem is that the ObjectName does not make the MBeans unique.
Example names:
JSPWiki:component=Core,name=Core bean
JSPWiki:component=Loggers,name=com.ecyrd.jspwiki.WikiEngine
So, depending on the order of startup, JSPWikiA or JSPWwikiB gets the MBean.
This can be a bit dangerous, you think you reload the Search manager for A, but
B gets it.
But apparently we don't have that many users that use both multiple wiki's and
the JMX.
I think we need something that makes the MBean names unique. Question is what
do we use :
1. property jspwiki.applicationName ? (still no guarantee)
2. context root of webapp (also no guarantee)
3. a random string appended, so this would make it like :
JSPWiki-BGJSKIR:component=Core,name=Core bean, not very elegant
4. something perfect, any idea's ?
The current AdminBeanManager also has a minor bug, saying it registers an MBean
while it didn't, I'll fix that soon.
