Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Release Notes

- Previous: Cannot restore backed-up domain with another name. (ID 6196993)
- Next: Cannot redeploy or undeploy the web module that is the default web module of any virtual server. (ID 6204799)

### Starting Application Server with additional JMX Agent is not supported. (ID 6200011)

J2SE 1.4.x, 5.0, or later can be configured on the Application Server. An integral feature of J2SE 5.0 platform is the ability to start a JMX agent. This is activated when you explicitly set system properties at the server startup.

Example values include:

    name="com.sun.management.jmxremote" value="true"
    name="com.sun.management.jmxremote.port" value="9999"
    name="com.sun.management.jmxremote.authenticate" value="false"
    name="com.sun.management.jmxremote.ssl" value="false"

After configuring JMX properties and starting the server, a new `jmx-connector` server is started within the Application Server VM. An undesirable side-effect of this is that the administration functions are affected adversely, and the Application Server administration GUI and CLI may produce unexpected results. The problem is that there are some conflicts between the built in `jmx-connector` server and the new `jmx-connector` server.

#### Solution

If using `jconsole` (or any other JMX-compliant client), consider reusing the standard JMX Connector Server that is started with Application Server startup.

When the server starts up, a line similar to the one shown below appears in the server.log. You can connect to the `JMXServiceURL` specified there and perform the same management/configuration operations after successfully providing the credentials; for example:

    [#|2004-11-24T17:49:08.203-0800|INFO|sun-appserver-ee8.1|javax.enterprise.
    system.tools.admin|_ThreadID=10;|ADM1501: Here is the JMXServiceURL for the
    JMXConnectorServer: [service:jmx:rmi:///jndi/rmi://hostname:8686/management/
    rmi-jmx-connector]. This is where the remote administrative clients should
    connect using the JSR 160 JMX Connectors.|#]
