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
