we have a few applications deployed with JBoss. All applications are packed as ear-files and placed in ...\server\default\deploy for deploying.
After deploying all applications are available.

But when we try to stop one of the applications via JMX Console. We get an error:

javax.servlet.ServletException: Failed to invoke operation
org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.invokeOp(HtmlAdaptorServlet.java:269)
org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.processRequest(HtmlAdaptorServlet.java:100)

root cause

The application, we try to stop, is still available.

Can somebody help? What is wrong here?

Thanks
