start /stop war via JMX w/ JBoss EAP 5.1

Question

I'm trying to make a UI tool to start/stop a webapp (war) on a Jboss EAP 5.1 via JMX, but I have a issue with security

public class jmx_console {
    //
    private static final Logger log = Logger.getLogger(jmx_console.class);

    //
    public static String startAndStopQueueManager(String jnpUrl, String qmUrl, String action, String username, String password) throws NamingException, MalformedObjectNameException, InstanceNotFoundException, MBeanException, ReflectionException,
            IOException, AttributeNotFoundException {
        //
        log.debug("username: " + username);
        log.debug("password: " + password);
        log.debug("action: " + action);
        log.debug("qmUrl: " + qmUrl);
        log.debug("jnpUrl: " + jnpUrl);
        //
        System.setProperty("java.security.policy", "client.policy");
        if (System.getSecurityManager() == null) {
            System.setSecurityManager(new RMISecurityManager());
        }
        //
        Properties ht = new Properties();
        ht.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
        ht.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
        ht.put(Context.PROVIDER_URL, jnpUrl);
        ht.put(Context.SECURITY_PRINCIPAL, username);
    ht.put(Context.SECURITY_CREDENTIALS, password);
        Context ctx = new InitialContext(ht);
        MBeanServerConnection mbeanConn = (MBeanServerConnection) ctx.lookup("jmx/invoker/RMIAdaptor");
        ObjectName queueManagerObjectManager = new ObjectName(qmUrl);
        mbeanConn.invoke(queueManagerObjectManager, action, null, null);
        return (String) mbeanConn.getAttribute(queueManagerObjectManager, "StateString");
    }

    public static void main(String[] args) {
        try {
            startAndStopQueueManager(args[0], args[1], args[2], args[3], args[4]);
        } catch (Exception e) {
            log.debug(ExceptionUtils.getStackTrace(e));
        }
    }
}

Args: localhost:1099, jboss.web.deployment:war=/QueueManager, start, admin, admin

and that's the exception:

Can you help me toubleshooting this issue ?

Answer 1

I think problem is with your security policy. More details http://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html

1 - assign the policy file correctly, either with a commandline flag:

java -Djava.security.policy=/home/.../<filename>.policy ...

or

System.setProperty("java.security.policy","file:///home/.../<filename>.policy");

You can also put it in the same folder as your project root), to reduce the URI to file:./<filename>.policy.

2 - make sure the format of the policy file is correct, e.g.:

grant codeBase "file:<path>/bin/-" {
    permission java.security.AllPermission;
};
