Launch an external application in a shell [message #532377]

Hello everybody,
I think my problem is quite common but I cannot find any interesting answer on the Internet.

I have developped an eclipse RCP application, and I would like to launch an external application (it's a Java Swing app, but it could also be any win32 application) to display it inside an editor.

I know it's possible, because under the Eclipse IDE, when I click on an image to display it, it launches a "mspaint.exe" process and display it inside the editor (without the menu bar).
But I cannot found how to do it.

I've found a small article showing an SWT shell hosting a win32 application (winrar) and saying that it uses org.eclipse.swt.internal.win32.OS, but it does not say precisely how that was done, and moreover it's an internal and non portable API.

Any idea how to do this ?

Thank you for your answers.

You should use 'Program' APIs of SWT framework for launching external
(may be default) application for any file associated with the platform.
For more info on the Program APIs, please refer to snippets (under
'Program' section) available at - http://eclipse.org/swt/snippets/

Paint is opened inside editor or view by using OLE api..

I think that not be used for u r purpose since its your own swing application.....

Although there are SWT AWT bridges awailable where u can put swing components inside swt components,,,,
May be this can be used...

Thank you for your answers.

What is the purpose of the "Program" API compared to the classical Java ProcessBuilder ?

I don't think I can use the SWT_AWT bridge, because I do not want to reuse components but launch a whole application (which could also be a native application), but I want it to be displayed inside a window of my RCP application.

Program is a utility class that provides support to launch any kind of
application for any kind of file type. It provides transparency from the
user to launch the default application, or a custom application for any
file type.
I think ProcessBuilder is more for managing/creating/instantiating
processes itself, nothing to determine the application for a filetype,
determining the available apps/extensions installed on the machine.
