com.ibm.as400.access.JavaProgram

All Implemented Interfaces:

Serializable

public class JavaProgram
extends Object
implements Serializable

Represents an IBM i Java program. This class is supported only when connecting to systems running IBM i V5R1 or higher, and is not supported beyond IBM i 7.1.

In the context of this discussion, a "Java program" is the IBM i executable object that is created when the CRTJVAPGM (Create Java Program) CL command is run against a class, JAR, or ZIP file.
Using the JavaProgram class, you can obtain the following information about an IBM i Java program:

• Adopted authority profile
• File change date
• File owner
• Java program creation date
• Release program was created for
• Licensed Internal Code options
• Number of attached java programs
• Number of classes
• Number of classes with current java programs
• Number of classes without current java programs
• Number of classes with errors
• Optimization level
• Path used
• Performance Collection Enabled flag
• Performance Collection type
• Profiling data status
• Size of attached java programs
• Use adopted authority

An Example using the JavaProgram class:

// Create a JavaProgram object to refer to a specific Java program.
AS400 system = new AS400("MYSYSTEM", "MYUSERID", "MYPASSWORD");
JavaProgram javaProgram = new JavaProgram(system, "/home/mydir/HelloWorld.class");


// Get the optimization.
int optimization = javaProgram.getOptimizationLevel();


// Get the file owner.
String owner = javaProgram.getFileOwner();
