PH22285: HOST JAVA APPLICATION CONFIGURATION DOES NOT DISPLAY SYSTEM.OUT

APAR status

• Closed as program error.

Error description

• In IBM Explorer for z/OS Version 3.1.1 or IBM Developer for z/OS
  - IDz - v14.2.1,
  when running or debugging a Java project using Host Java
  Application configuration, Console view doesn't display
  System.out messages.
  It does display System.err messages.
  
  
  Steps to reproduce:
  
  - create a Java project (ie MyZosJava)
  - change the local bin output folder to a RSE USS directory
  On Java Build path properties, click on browse then Create New
  Folder then Advanced and check Link to Folder in the file system
  and select RSE.
  - create a Java main class like
  
  package test;
  
  public class MyMain {
  
      public static void main(String[] args) {
          String msg = "Hello Java z/os World";
          System.out.println(msg);
          System.err.println(msg);
      }
  
  }
  
  - from menu Run > Debug > Debug configurations..., create a new
  Host Java Application configuration (named for example JavaZos)
  referencing the above Java project and main class
  - On Common tab, make sure that Allocate console is checked
  - Click on Debug => A console "JavaZos test.MyMain" is created
  on the Console view tab.
  - On the Debug view, resume or step over all lines and observe
  that only one red message is written to the console.
  

Local fix

• When running or debugging, IDz will open a new USS shell which
  can be found on Remote Systems Explorer under the MVS connection
  and z/OS Unix Shells.
  Open this remote shell into the Remote Shell view to view
  System.out messages.
  

Problem summary

• System.out not displayed in console when running host java
  application
  

Problem conclusion

• The System.out produced in a java program is not getting
  displayed in the console view when using a Host Java Application
   configuration.
  

Temporary fix
