 why the sheel command is not able to execute
the ".jar" files like ".exe" files even though they are
also exes but in terms of Java. What i want is, if user pushes
certain button on the form then a file,"abc.jar", should be executed.
Is there another way of doing it??

Thanx in advance

.jar files are NOT like .exe file to Windows's point of view ! .jar file can only be excuted via Java's VM.

So, if you want to shell a .jar file, try instead this kind of command:

shell "java myProg.jar"

I don't have any longer Sun's Java SDK on my machine, as far as i remember, but this should work.

You can find more options concerning java'c command line arguments into Sun's documentation.

Hope this helps.

go to MyComputer->View->Options->File Types

then under edit file type you can find the command that is being used to open a java file

for example, on my pc for a .pdf file I have under open

"C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe" "%1"

then if in VB I do

Shell "C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe c:\download\sp35ug.pdf"

I launch the pdf in a reader.

Here is a great alternative for you. Just give it a path to your .exe or any other file that is associated with an application and it'll run it for you:
' create a new VB project
' Copy+Paste on a module
Private Declare Function ShellExecute _
   Lib "shell32.dll" Alias _
   "ShellExecuteA" (ByVal _
   hWnd As Long, ByVal lpOperation As _
   String, ByVal lpFile As String, _
   ByVal lpParameters As String, _
   ByVal lpDirectory As String, _
   ByVal nShowCmd As Long) As Long

' Copy+Paste into same module
Sub RunApp(frm As Form, strXLS As _
   String, intWindowStyle As Integer)

   Dim lngSuccess As Long

   'launch the default browser
   lngSuccess = ShellExecute( _
      frm.hWnd, "Open", _
      strXLS, 0&, 0&, intWindowStyle)

End Sub

'Create a button on a form and then copy+paste
Private Sub cmdRunApp_Click()
    Dim sPath As String
    sPath = InputBox("Enter path")
    RunApp Me, sPath, 1
End Sub
