Solved: Mac/Linux trigger Java GUI Scripting from command ...

Scenario

I am able to trigger a javascript file from command line like this:

test1.js

application.openConnectionByConnectionString("conn=/H/10.10.10.100/S/3200&expert=true");
application.findById("/app/con[0]/ses[0]/wnd[0]/usr/txtRSYST-MANDT").text = "220";
application.findById("/app/con[0]/ses[0]/wnd[0]/usr/txtRSYST-MANDT").setFocus();
application.findById("/app/con[0]/ses[0]/wnd[0]/usr/txtRSYST-MANDT").caretPosition = 3;
application.findById("/app/con[0]/ses[0]/wnd[0]/usr/txtRSYST-BNAME").text = "username";
// The text of a password field is not recorded. Either enter a valid password or delete the following line
application.findById("/app/con[0]/ses[0]/wnd[0]/usr/pwdRSYST-BCODE").text = "secret";
application.findById("/app/con[0]/ses[0]/wnd[0]").resizeWorkingPane(181,35,false);
application.findById("/app/con[0]/ses[0]/wnd[0]").sendVKey(0);
application.findById("/app/con[0]/ses[0]/wnd[0]/tbar[0]/okcd").text = "/nex";
application.findById("/app/con[0]/ses[0]/wnd[0]").sendVKey(0);

#!/bin/bash
export SAPGUIDIR="/Applications/SAP Clients/SAPGUI 7.50rev5/SAPGUI 7.50rev5.app/Contents/Resources"
export WORKDIR=`pwd` # this is where the script file is located

cd "${SAPGUIDIR}"
echo "[DEBUG] starting..."

java \
	-cp Java/GuiStartS.jar com.sap.platin.Gui \
	-n \
	-b \
	-f ${WORKDIR}/test1.js

echo "[DEBUG] done!"

Problem
JavaGUI does not quit. There is a popup that says "The script has successfully completed its execution".

If I run the command again, I get another copy of JavaGUI running ...

How can I get JavaGUI to quit completely?

Please could anyone share a link to the full JavaScript API?

On macOS just add parameters "-t NOPHANTOM" in the script, then the JavaGUI will exit when the connection is closed.

And instead of calling "java ... -jar GuiStartS.jar..." you can call

"/Applications/SAP Clients/SAPGUI 7.50rev5/SAPGUI 7.50rev5.app/Contents/MacOS/SAPGUI -n -b ...."

This will start the JavaGUI with the appropriate java version.

In case someone comes across this thread and that they're having issues with SAPGUI for Java 7.80:

The NOPHANTOM trace appears to be replaced with SCRIPTNOMESSAGE
- The reason why this works is because setting this trace (as a side effect) puts SAPGUI into "unattended mode"
If you rather not use SCRIPTNOMESSAGE (and see unnecessary tracing) then at the beginning of your script you can do the following (undocumented) trick:
- ```
application.unwrap(application).mUnattended = true;
```
I know there are references in this thread about how the SAPGUI can/will exit after the script completes and elsewhere in the SAPGUI documentation it suggests that closing connections/sessions should shutdown the SAPGUI -- but this has not been my experience.
- After closing the connections/sessions and confirming it completed with the SHUTDOWN trace, at the end of my script I now call:
  - ```
  java.lang.System.exit(0);
```
- NOTE: This will not work with the Java Security policy that is shipped with the SAPGUI. I had to call the SAPGUI using Java (like the author originally did) and pass in the absolute path for a custom security policy to the JVM at start up:
  - ```
  java -Djava.security.policy=file://...
```
- The contents of the security policy I used are:
  - ```
  grant principal com.sap.platin.micro.GuiPrincipal "SAPGUI:UserScript" {
      permission java.io.FilePermission "<<ALL FILES>>", "read,write,delete,execute";
      permission java.lang.RuntimePermission "getenv.*";
      // Generic Permissions necessary for Scripting
      permission javax.security.auth.AuthPermission "doAsPrivileged";
      permission java.awt.AWTPermission "createRobot";
   
      // Allow the script to exit
      permission java.lang.RuntimePermission "exitVM";
  };
```

The public trace keys are listed in chapter "5.3.3 Trace Information" of the manual available via Help > SAP GUI Help. They usually are intended to switch on tracing in particular components for debugging purposes.

There are a few more to modify the behavior, but they are not published by intention.

Using parameter -? will print the list of parameters.
