Question

Creating new mail (default client) from Java/Windows

Answer 1

+2 A:

Desktop dt = Desktop.getDesktop();
dt.mail();

will open the default mail client (the one associated with mailto: protocol).

As you see, I want subject and body as well. I would have loved an attachment, but from what I've read, it's not doable.

The API supports that.uriMailTo = new URI("mailto", "[email protected]?subject="+ subject+"dt.mail(uriMailTo);

Excellent, thank you! I've read some on getting attachments in, but found no real substance. JDIC (which we just finally got rid of) and http://stackoverflow.com/questions/81862/how-do-i-send-an-email-attachment-using-the-designated-client-programmatically-f are the best I've seen, and none of them are good enough. You wouldn't happen to know more?

AFAIK that's a limitation of the mailto: protocol, you can't specify an attachment.

Answer 2

+1 A:

I found the answer when googling for rundll.exe:

String subject = ...;
String body = ...;
String cmd = "rundll32.exe shell32.dll,ShellExec_RunDLL \"mailto:[email protected]?"+
             "subject="+subject+"&body="+body+"\"";
Runtime.getRuntime().exec(cmd);

Sorry for wasting your time!

Jonas: Have you tried ShellExecute() instead of relying on undocumented implementation details that are likely to change in future versions of Windows?

Larry: I didn't think there was one for Java? As to JNI-ing it, I very much prefer two lines of Java code that might (probably not though) require minor adjustments to 50 lines of code spread over Java, C and build system.
