Error R0035 - PB 12.5 - java

I try to run this command:

java -jar "C:\programa.jar"

Using:

OleObject ole_wsh

integer   iRet

string    scmd

ole_wsh = Create OleObject

iRet = ole_wsh.ConnectToNewObject("WScript.Shell")

if iRet<0 then

   DESTROY ole_wsh

   MessageBox("No se pudo conectar a windows shell", "Error: " + String(iRet))

   Return

end if

scmd = 'java -jar "C:\programa.jar"'

iRet = ole_wsh.Run(scmd, 2, TRUE)

if iRet <> 0 then

   MessageBox("No se pudo ejecutar el comando " + scmd, "Error: " + String(iRet))

end if

ole_wsh.DisconnectObject ( )

DESTROY ole_wsh

But the application show:

Power Builder application execution error (R0035)
