CommandCall class

The CommandCall class in the micro package (com.ibm.as400.micro.CommandCall) provides a modified subset of the functions available in the CommandCall class in the access package (com.ibm.as400.access.CommandCall). Use the CommandCall class to call an iSeries™ command from a Tier0 device.

The CommandCall run() method requires a String (the command you want to run) and returns any messages resulting from running the command as a String. If the command completes but does not generate any messages, the run() method returns an empty String array.

Example: Using CommandCall

The following example demonstrates how you can use CommandCall:

   // Work with commands.
   AS400 system = new AS400("mySystem", "myUserid", "myPwd", "myMEServer");
   try
   {
       // Run the command "CRTLIB FRED."
       String[] messages = CommandCall.run(system, "CRTLIB FRED");
       if (messages != null)
       {
           // Note that there was an error.
           System.out.println("Command failed:");
           for (int i = 0; i < messages.length; ++i)
           {
               System.out.println(messages[i]);
           }
       }
       else
       {
           System.out.println("Command succeeded!");
       }
   }
   catch (Exception e)
   {
       // Handle the exception
   }
   // Done with the system object.
   system.disconnect();
