How to access server MBean properties at weblogic 11g using Java – JMX


If you want to get any property of Admin or Managed Server (Weblogic) using Java, then this post will help you.

The Oracle Enterprise Manager have a useful tool for explore MBean (System MBean Browser).

As you can see in the picture bellow:

Do you can to capture any server property desired with these java code:

1 – Reading a property if the application is deployed at server (local connection)

import javax.naming.InitialContext;

String serverName = System.getProperty("weblogic.Name");
InitialContext ctx = new InitialContext();
MBeanServer server = (MBeanServer)ctx.lookup("java:comp/env/jmx/runtime");
ObjectName objName = new ObjectName("com.bea:Name=" + serverName + ",Type=Server");
String pathJKS = (String) server.getAttribute(objName, "CustomTrustKeyStoreFileName");

2 – Reading a property if the application is remote (remote connection)

import java.util.Hashtable;
import javax.naming.Context;

  public static void main(String [] args) throws Exception{
    String serverName = "AdminServer";
    String hostName = "";
    String username = "weblogic";
    String password = "welcome1";
    int port = 10000;
    String protocol = "t3";
    String jndiroot = "/jndi/";
    String mserver = "";
    JMXServiceURL serviceURL = new JMXServiceURL(protocol, hostName, port, jndiroot + mserver);
    Hashtable h = new Hashtable();
    h.put(Context.SECURITY_PRINCIPAL, username);
    h.put(Context.SECURITY_CREDENTIALS, password);
    h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES, "");
    JMXConnector connector = JMXConnectorFactory.connect(serviceURL, h);
    ObjectName objName = new ObjectName("com.bea:Name=" + serverName + ",Type=Server");
    String pathJKS = (String) connector.getMBeanServerConnection().getAttribute(objName, "CustomTrustKeyStoreFileName");

In the cases above, i’m reading a property that is called “CustomTrustKeyStoreFileName”, that’s a string path of the Trusted Keystore. But many and many properties could be read, for example:

  • CustomIdentityKeyStoreFileName
  • ListenPort
  • UploadDirectoryName

That’s it.
