How to start a Java Console App out of Servoy?

Classic Servoy
1

As the Subject tells:
I am trying to run a Java Console Application out of servoy.
I found the method :
application.executeProgram( )

Whe I try this:
application.executeProgram( ‘c:/report/BewerberhandoutApp.jar’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)
I get the exception:

java.io.IOException: CreateProcess error=193, %1 ist keine zulässige Win32-Anwendung (This is not a valid Win32-Application)
Which, in my mind, Is correct.
But if I try this:
application.executeProgram( ‘java - jar c:/report/BewerberhandoutApp.jar’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)
I get the Exception:
java.io.IOException: CreateProcess error=2, Das System kann die angegebene Datei nicht finden (The System is unable to find the specified file)

So i tried to execute a batch file:
application.executeProgram( ‘c:/report/startBwh.bat’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)
but now Nothing happens…
No Console popping up, or anything else.
Anybody an idea to solve this?

Thanks in advance!

P.S. executeProgrammInBackground doesnt work either…

GevatterTod:
application.executeProgram( ‘c:/report/startBwh.bat’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)

I don’t think this will work because the application arguments should be available to the java app (unless you read them in with the bat file).

GevatterTod:
application.executeProgram( ‘java - jar c:/report/BewerberhandoutApp.jar’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)

I have not tried it but what happens when you split the first argument ‘java - jar c:/report/BewerberhandoutApp.jar’ into three ‘java’, ‘-jar’ , ‘c:/report/BewerberhandoutApp.jar’ but before you do that, while copying your line I noticed there is a space between ‘-’ and ‘jar’ that should not be there…

Quite in fact the Programm doesn’t need any Arguments, because it gets the needed value by a User input in the console during runtime of the App.

The Space is a mistyping I only had in this post.
When I tried out there has been no Space in the line.

I tried to split the Arguments like this:

function meth_report_allCompanys_projekt()
{
	var myPath = 'C:\\report\\BewerberhandoutApp.jar';
	var myPath2 = 'C:\\report\\startBwh.bat';
  	var jsFile = plugins.file.convertToJSFile(myPath);
	var jsFile2 = plugins.file.convertToJSFile(myPath2);
	var java = "java ";
	var jar = "-jar ";
		
  	if (!jsFile.exists() || !jsFile2.exists()) {

  	plugins.dialogs.showErrorDialog( "Fehler",  "Die benötigten Dateien befindet sich nicht auf ihren Rechner! Bitte wenden sie sich an ihren Administrator",  "OK")

  	}
  	else
  	{	
  		application.executeProgram( java + jar + myPath, '#', 'path=c:/report', '#', 'c:/report')
  	}

	
}

Console output:

Fehler beim Starten des Programms:java -jar C:\report\BewerberhandoutApp.jar
 > java.io.IOException: CreateProcess error=2, Das System kann die angegebene Datei nicht finden

The HardCoded Versions:

application.executeProgram( "java -jar \"C:\\report\\BewerberhandoutApp.jar\"", '#', 'path=c:/report', '#', 'c:/report')

application.executeProgram( "java -jar C:\\report\\BewerberhandoutApp.jar", '#', 'path=c:/report', '#', 'c:/report')

dont work as well.
Even though the both lines Above work when executed in a windows command line.

And this:```
application.executeProgram( ‘java’, ‘-jar’, ‘C:\report\BewerberhandoutApp.jar’, ‘#’, ‘path=c:/report’, ‘#’, ‘c:/report’)

btw I am not even sure you can call a java command from java…

Well. It looks like something happens, but the client freezes if i execute the method… :(

Looks like I have to find another way round.

Despite:
Thank you very much for spending your time on my problem ;)

BewerberhandoutApp.jar

What is this doing?
Is it something you made yourself?
Maybe it is easy to change it into a Plug-in?
When it can be changed I might be able to help you. In that case please send an email to contact at it2be dot com
