Question

I have created an application window using Java swing. I need to call my java exe file using powershell.. The Java application is done using java swing..I have exported the Java application to a jar file.. While double clicking the exe file i get the output executed.. My powershell code is this

$psi = new-object System.Diagnostics.ProcessStartInfo
$psi.CreateNoWindow = $true $psi.UseShellExecute = $false
 $psi.FileName = 'java.exe' $psi.Arguments =
 @("-classpath","$Env:CLASSPATH","D:\")
[System.Diagnostics.Process]::Start($psi) set-item -path Env:CLASSPATH
-value :\D:\ "CLASSPATH = $Env:CLASSPATH"  [Diagnostics.Process]::Start('java.exe','-classpath $Env:CLASSPATH
 D:\Swing.jar')

I am geeting a black window displayed and no errors.. My application program window is not displayed

Two things:

1. You need the -jar option to Java, as Sanjeev already noted.

2. Please don't write PowerShell as if it were some kind of C# with funky syntax. There is a Start-Process cmdlet, after all, if you really need it:

    Start-Process -FilePath java.exe -ArgumentList -jar,D:\\Swing.jar,-classpath,$Env:CLASSPATH -NoNewWindow 

   In this case you probably don't, so the following should work just as well (remember, PowerShell is a shell, hence the name; running programs is quite easy):

    java -jar D:\\Swing.jar -classpath $Env:CLASSPATH 

And if you don't want to have the console output, then use javaw instead of java . Control will return immediately to PowerShell, then, though.
