[jboss-user] [JBossCache] - Re: Cannot see nodes and attached map in JMX console

Thanks. I get the following error message by using 
Fqn.fromString()
javax.management.IntrospectionException: Failed to find PropertyEditor for type: org.jboss.cache.Fqn
	org.jboss.jmx.adaptor.control.Server.invokeOpByName(Server.java:251)
	org.jboss.jmx.adaptor.control.Server.invokeOp(Server.java:223)
	org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.invokeOp(HtmlAdaptorServlet.java:262)
	org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.processRequest(HtmlAdaptorServlet.java:100)
	org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.doPost(HtmlAdaptorServlet.java:82)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:710)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
	org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

However, I am going to use TreeCache to resolve issue like case as follows:
No      User A                                User B
1      Request  read  v(= 5)                                   
2                                         Request  read  v( =5 )
3                                         Change v (8) (screen)
4      change v (6) (screen)
5                                         save v Transaction Tb
6      save v Transaction Ta

I want to protect variable v without querying database. So User A save action should be rejected.  To do this,  Ta need know v is changed by Tb. Ta start after Tb finish. 

Thank you again,

Bill
