Exception in thread "main"
*******************************************
...here is string arguement I'm passing to the VM:
*******************************************
-Djava.library.path=C:\Program

*******************************************
...this path is absolutely correct, I copied it right out of Win Explorer
rather than typing it in manually.
Here's the code (generated by VE)
********************************************

public class SWTMain {
private org.eclipse.swt.widgets.Shell sShell = null; //
@jve:decl-index=0:visual-constraint="128,49"
private Combo combo = null;
/**

private void createCombo() {
combo = new Combo(sShell, SWT.NONE);
combo.setBounds(new org.eclipse.swt.graphics.Rectangle(155,43,232,21));
}

*/
org.eclipse.swt.widgets.Display display =
org.eclipse.swt.widgets.Display.getDefault();
SWTMain thisClass = new SWTMain();
thisClass.createSShell() ;
thisClass.sShell.open();
while (!thisClass.sShell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep ();
}
display.dispose();
}
/**
* This method initializes sShell
*/
private void createSShell() {
sShell = new org.eclipse.swt.widgets.Shell();
createCombo();
sShell.setSize(new org.eclipse.swt.graphics.Point(398,267));
sShell.setText("SWT is wicked cool!");
}
}
********************************************
Can anyone help? I can run SWT apps built in VE all day long on linux/gtk
but I can't get it to work in windows regardless of what version of
eclipse I use (have tried 3.0.1 and now 3.1M2)...
Thanks!

I moved my eclipse IDE directory to the C:\ drive and ran it there (no
spaces in VM arguements) and it ran fine.
Seems like a silly limitation? Is there a way around this (ability to
have spaces in diretory structure?)
Thanks!

Try putting double quotes around the path if it has spaces. ie:
-Djava.library.path="C:\Program Files\eclipse\..."
