I'm attempting to deploy my application to Tomcat 6 and receiving the
following error when I hit the application:

The code is attempting to open a login dialog. The application works just
great when running in the IDE, but the deployed version on Tomcat does not.
I'm using the M2 version which now supports the readAndDispatch. I believe
I'm packaging all the correct versions of rwt as shown in my osgi status:

Hi,
Coincidentally, I actually saw the same thing today (including the "Z",
which I don't understand). We have an application originally written
against SWT that we are porting to RWT. We are able to leave a majority
of our classes in their original projects, which have SWT in the project
compile-time classpath, and simply run against RWT (comment/criticism on
this strategy is welcome). As long as we don't use methods that are not
implemented in RWT this strategy generally works. However for some
classes, we need to compile against RWT as well. This was the case with
the class I was porting today with a read and dispatch loop:
if (!display.readAndDispatch())
display.sleep();
It is not clear to me why this caused the NoSuchMethodError where many
other similar cases don't. In fact, a call to Display.readAndDispatch()
in the same class, compiled against SWT but run against RWT, ran fine,
correctly entering into the RWT method, but the next line, the call to
Display.sleep(), gave the NoSuchMethodError.
Changing this class to compile against RWT solved this problem.
Frank, can you shed any light on this?
Thanks,
Ryan

Hi,
the Z means "return type of type boolean" which is correct for SWT but
not for RWT. Without checking the return type of sleep the code is still
source compatible but not binary compatible as the return parameters are
different (void for RWT, boolean for SWT). Maybe Frank can clarify if we
we have time and way to be compatible. In the meantime you should
compile your code against RWT instead of SWT.
