Interface AppDeploymentMBean

All Known Subinterfaces:

DeploymentServiceMBean

public interface AppDeploymentMBean

extends WebLogicMBean, javax.management.NotificationEmitter

This MBean will manage the deployment of a deployable application in the Weblogic Event Server or in a cluster of WebLogic Event Servers.

In a non-clustered environment, a Weblogic Event Server domain contains a single Event Server instance. In a clustered environment, a Weblogic Event Server domain contains groups of servers. A group represents a collection of homogeneous Weblogic Event Server instances. The application name is unique within a domain. Likewise, the group name is unique withing a domain.

This Mbean also manages the following lifecycle of a deployable application:

• Deploys a deployable jar file or a serialized byte array to the an Event Server instance or to a group.
• Undeploys a deployed application
• Updates a deployed application
• Suspends a deployed application
• Resumes a deployed application
• Queries for applications that have been deployed at this Event Server instance.

An example of using this MBean to manage the life cycle of a deployed application is given below

      //get the remote JMX service URL assuming RMI protocol and the listening RMI port is 1099
      JMXServiceURL url = new JMXServiceURL("rmi", "localhost",1099, "/jndi/rmi://localhost:" + 1099 + "/jmxrmi");

      //get a remote JMX connector
      JMXConnector jmxc = JMXConnectorFactory.connect(url,null);

      //get the MBean server connection
      MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();

      //get the AppDeployment MBean name as registered in the MBean server
      ObjectName deploymentName =
         ObjectName.getInstance("com.bea.wlevs:Domain=" + domainName 
             + ",Name=AppDeployment,Type=AppDeployment");

      //look up the AppDeployment MBean
      AppDeploymentMBean deploymentMBean = (AppDeploymentMBean)
             MBeanServerInvocationHandler.newProxyInstance(
                              mbsc,
                              deploymentName,
                              AppDeploymentMBean.class,
                              true);

      //deploy
      System.out.println("\n\t Deploying application - helloworld");
      deploymentMBean.deployApplication("helloworld",
              new File("com.bea.wlevs.example.helloworld_3.0.0.0.jar"));

      //get the list of applications deployed in the server
      Collection<String> deployments = deploymentMBean.listDeployedApplications();

      for(String s : deployments) {
          System.out.println("\n\t Deployed Application " + s);
      }

      //suspend the application
      Thread.sleep(10000);
      System.out.println("\n\tSuspend application helloworld");
      deploymentMBean.suspend("helloworld");

      //resume the application
      Thread.sleep(10000);
      System.out.println("\n\tResume application helloworld");
      deploymentMBean.resume("helloworld");

      //undeploy
      Thread.sleep(10000);
      System.out.println("\n\tUndeploying application helloworld");
      deploymentMBean.undeployApplication("helloworld");

      //close the MBean remote connection
      jmxc.close();
