Initial debugging displays for Java programs

As you debug your Java™ programs, follow these example displays for your programs. These displays show an example program, named Hellod.

  • Enter ADDENVVAR ENVVAR(CLASSPATH) VALUE ('/MYDIR').
  • Enter this command: RUNJVA CLASS(HELLOD) OPTION(*DEBUG). Insert the name of your Java program in place of HELLOD.
  • Wait for the Display Module Source display to appear. This is the source for the HELLOD Java program.

  • When adding a class to debug, you may need to enter a package-qualified class name that is longer than the Program/module input field. To enter a longer name, follow these steps:
    1. Enter Option 1 (Add program).
    2. Leave the Program/module field blank.
    3. Leave the library field as *LIBL.
    4. Enter *CLASS for Type.
    5. Press Enter.
    6. A pop up window is displayed where you have more room to enter the package-qualified class file name. For example: pkgname1.pkgname2.classname
