Is this an efficient way....

Hello Pro's,
I am trying to run an iSeries command from a .jsp page and this is how I am
doing it. I was wondering if anybody could give their opinion on this
approach. I am trying to follow the example by Kevin Vandever. The example
runs just fine if I run it as a .java stand alone application. Any help
would be much appreciated.

       String systemString  = null;
       String commandString = null;
       String successful = "Command Was Successfully Executed";
       String failed = "Command Failed To Execute, Please Try Again";

       try
       {
           commandString = "CALL VND999CL";
       }
       catch (Exception e) {};

       AS400 as400 = new AS400("XXX.XXX.XXX.XXX", "XXX", "XXX");

       CommandCall command = new CommandCall( as400 );



       try
       {
          if (command.run(commandString))
              out.println( "Command successful" );
          else
              out.println( "Command failed" );

          AS400Message[] messagelist = command.getMessageList();

          if (messagelist.length > 0)
          {
              out.println( ", messages from the command:" );
              out.println( " " );
