How do I actually run the code generated from VE? When I try to run the
code, I get the following (see below at the end of the message). The
tutorial at
http://www-106.ibm.com/developerworks/opensource/library/os- ecvisual/
says to put something like what follows in the arguments:
-Djava.library.path=C:\eclipse\plugins\org.eclipse.swt.win32 _3.0.0\os\win32\x86
but I do not see a 'org.eclipse.swt.win32...' plugin any where. I wonder
what I could do to run the code? Thanks.
Regards...
Miguel.

Thanks for this update. I was not sure of what I was doing wrong because
I could not get any thing to work.
Using E.3.1, with the latest VE nightly build, how could I run the VE
SWT example? I do not find the org.eclipse.swt.win32_3... plugin. Is
this broken somehow, or... I am not too sure of what to do. The following:
-Djava.library.path=" installation_directory\plugins\org.eclipse.swt.win32_3.0.0\o s\win32\x86
seems not to be an option? Thanks for your suggestions.
Regards...
Miguel.

Thanks for your help.
The SWT launcher did not work, but we know this now.
With regard to the article, I have not been able to put time into this
yet, but it does look very promising. I think that the format is
adequate, and the message does get across. It seems that the article is
adequate at least for folks at my proficiency level ( <= medium).
Thanks for the efforts that have gone in the article.
I am interested in a 2D plot widget that scrolls as inputs come by. I
will use your article to see if I can do something along this line.
Thanks again.
Regards...
Miguel.
