All Implemented Interfaces:

Deprecated. Use Java Swing instead, along with the classes in package com.ibm.as400.access

public class VJavaApplicationCall
extends JComponent
implements KeyListener

The VJavaApplicationCall class provides a visual interface to com.ibm.as400.access.JavaApplicationCall. The visual interface consists of two components: an input field where the program to run is specified and input is sent to the program, and an output text area where the output from the program is displayed.

GUI output generated by the Java program running on the system is not handled by this class. As in JavaApplicationCall, the Java program running on the system receives input via standard. The output text area displays output the system java program writes to standard out and standard error. GUI input/output must be handled via another mechanism such as Remote AWT.

There are two ways to set up the system Java environment:

1. VJavaApplicationCall must have a JavaApplicationCall object. After creating the JavaApplicationCall object, the application can set environment parameters on the JavaApplicationCall, object, then construct the VJavaApplicationCall object passing it the JavaApplicationCall object. The advantage to this method is the application sets up the environment instead of the user.
2. The environment can be set up via set commands entered in the GUI. For additional information on these commands, see the on-line help for the Java command. Valid commands are:
   • Classpath - the value of the CLASSPATH environment variable. Directories are separated by colons.
   • DefaultPort - the default port for communicating standard in, standard out and standard error between the client and the system java environment.
   • FindPort - indicates if the client should search for a free port if the default port is in use.
   • Interpret - indicates if all Java class files should be run interpretively.
   • Optimize - the optimization level for classes not yet optimized.
   • Options - additional options used when running the Java class.
   • SecurityCheckLevel - the level of warnings given for directories in the CLASSPATH that have public write authority.
   • GarbageCollectionFrequency - the relative frequency that garbage collection runs.
   • GarbageCollectionInitialSize - the initial size, in kilobytes, of the garbage collection heap.
   • GarbageCollectionMaximumSize - the maximum size, in kilobytes, that the garbage collection heap can grow to.
   • GarbageCollectionPriority - the priority of the tasks running garbage collection.
   For example, to send the optimization level to 30, enter
   

   set optimize=30
   

You start the Java application using the java command. The syntax for this command is much like the syntax when running the command on the client. It is

java [-classpath=value] [-verbose] [-Dproperty=value -Dproperty=value [...]] class [parm1 parm2 [...]]]

Note, this class correctly sets the standard in, standard out and standard error properties so os400.stdin, os400.stdout or os400.stderr properties are ignored. For example, to run Java application

java -classpath=/myClasses:/myClasses/lib/package.jar myProgram parm1 parm2

To use this class you simply create a frame to contain the class then call the load() method to run the start the application. For example,

AS400 system = new AS400("myAS400");

 JavaApplicationCall javaCall  = new  JavaApplicationCall(system);
VJavaApplicationCall vJavaCall = new VJavaApplicationCall(javaCall);

JFrame f = new JFrame ("JavaApplicationCallExample");
f.getContentPane().setLayout(new BorderLayout ());
f.getContentPane().add("Center", vJavaCall);
f.pack();
f.show();
