How To Use PowerShell Script Inside Java

Hello community,

I wrote here about the using of SAP GUI Scripting inside Java. Also I wrote here, here, here and here about the using of PowerShell inside ABAP. Here now a combination of both. I use JaCoB (Java COM Bridge) with SAPIEN Technologies ActiveX PowerShell library. On this way it is possible to use PowerShell seamless and easily inside Java.

        public static void main(String[] args) {

        ComThread.InitSTA();

        ActiveXComponent PS = new ActiveXComponent("SAPIEN.ActiveXPoSHV3");

        try {

              if (PS.invoke("Init", false).changeType(Variant.VariantInt).getInt() != 0) {

            throw new RuntimeException();

          }

          if (PS.getProperty("IsPowerShellInstalled").changeType(Variant.VariantInt).getInt() == 0) {

            throw new RuntimeException();

          }

          PS.setProperty("OutputMode", OUTPUT_BUFFER);

          PS.invoke("ClearOutput");

          String PSCommand = "Get-Host;$PSVersionTable.PSVersion";

          PS.invoke("Execute", PSCommand);

          String Output = PS.getProperty("OutputString").toString();

          System.out.println(Output);

        }

        catch (Exception e) {

          System.out.println("An exception has occurred");

        }

        finally {

          ComThread.Release();

          System.exit(0);

        }

      }         

    }

//-End------------------------------------------------------------------

With regard to the Eclipse IDE this may be an interesting aspect - but I must admit a little bit exotic.

Enjoy it.

Cheers
