Edit applications

 

You can edit deployed applications through the console, the wsadmin tool, or by programming. Use this example to edit a deployed application through programming. This task assumes a basic familiarity with MBean programming. For information on MBean programming, see MBean Java application programming interface (API) documentation.

Before you can edit an application on WAS, first install the application.

 

Overview

Perform the following tasks to edit your deployed application.

 

Procedure

1. Connect to WAS.

2. Create the application management proxy.

3. Get information about an installed application.

4. Manipulate task data as necessary.

5. Save changes for the installed application.

 

Results

After you successfully run the code, the application is edited.

 

Example

The following example shows how to edit an application, based on the previous steps.

import java.lang.*; import java.io.*; import java.util.*; import java.lang.reflect.*; import com.ibm.websphere.management.application.*; import com.ibm.websphere.management.application.client.*; import com.ibm.websphere.management.*;
 import javax.management.*;
 public class aa {

    public static void main (String [] args) {

        try {
             
  // Connect to WAS.
  String host = "localhost";
  String port = "8880";
  String target = "WebSphere:cell=cellName,node=nodeName,server=server1";

  Properties config = new Properties();
  config.put (AdminClient.CONNECTOR_HOST,  host);
  config.put (AdminClient.CONNECTOR_PORT,  port);
  config.put (AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP);
  System.out.println ("Config: " + config);
     AdminClient _soapClient = AdminClientFactory.createAdminClient(config);
  
  // Create the application management proxy, AppManagement.
  AppManagement proxy = AppManagementProxy. getJMXProxyForClient (_soapClient);

  String appName = "MyApp";
// Get information for an application with name appName:
// Pass Locale information as the preference.
Hashtable prefs = new Hashtable();
 prefs.put(AppConstants.APPDEPL_LOCALE, Locale.getDefault()); 
Vector allTasks =  appMgmt.getApplicationInfo (appName, prefs, null); 

// Manipulate task data as necessary. if (task.getName().equals ("MapRolesToUsers") && !task. isTaskDisabled()) 
{ 
       // find out column index for role and user column 
       // refer to the previous table to find the column names
       int roleColumn = -1;
       int userColumn = -1;
       String[] colNames = task.getColumnNames();
       for (int i=0; i < colNames.length; i++)
       { 
            if (colNames[i].equals ("role"))
              roleColumn = i;
            else if (colNames[i].equals ("role.user"))
               userColumn = i; 
       } 
            
       // iterate over task data starting at row 1 as row0 is
       // column names
       String[][]data = task.getTaskData();
       for (int i=1; i < data.length; i++)
       {
            if (data[i][roleColumn].equals ("Role1")) 
            {
              data[i][userColumn]="User1|User2";
               break;
            }
       } 
       
       // now that the task data is changed, save it back
       task.setTaskData (data);
} 

// Save changes back into the installed application:
// Set information for an application with name appName. 
// Pass Locale information as the preference. prefs = new Hashtable(); prefs.put(AppConstants.APPDEPL_LOCALE, Locale.getDefault()); appMgmt.setApplicationInfo (appName, prefs, null, allTasks);

        }
        catch (Exception e) {
            e.printStackTrace();
        }

    }
