calc example does not work with RAP from CVS [message #84506]

Eclipse User

Hi,

The calculator example
( http://rapblog.innoopract.com/2008/03/getting-started-with-c alculator-example.html)

does not work against RAP from CVS. It does work fine against the RAP
1.1M3 target platform. I am on Eclipse 3.3. When I run (Calculator
Example.launch and then http://127.0.0.1:8080/rap?startup=calc), I get
the following error:

Hi Ryan,

between M3 and HEAD we did a split of the RWT layer. This resulted in a
plugin (org.eclipse.rap.rwt) and a fragment (org.eclipse.rap.rwt.q07).
Be sure to add the q07 fragment to your launch configuration when
starting the server.
