Why do want to enable the InvokerServlet? There are different ways of
handling this, depending on the reason.
Cheers,
Larry

I personally find the invoker servlet very useful when learning,
experimenting, and testing out capabilities. But of course you should
never have the invoker servlet enabled in projects you are going to deploy.
Anyhow, when you use your own version of Tomcat 6.x with MyEclipse, it
automatically uses the configuration files in the install_dir/conf folder.
You have to edit two of these to enable the invoker servlet (the servlet
and servlet-mapping entries in web.xml, and you have to change 'Context'
to 'Context reloadable="true" privileged="true"' in context.xml). But
regular Eclipse uses its own deployment and configuration folders. You can
copy the files from the standard "conf" folder, or you can double click on
the server and tell it to use your existing folders.
Again, I want to stress that you should not use the invoker servlet for
deployed applications. But, I find it very useful when learning and
experimenting with temporary projects.

I am not sure either. But in one (of the many) hats that I wear, I teach
Java Web app programming in the Johns Hopkins part-time graduate program
in Computer Science. Students are free to use any IDE they want, and some
use MyEclipse, some use regular Eclipse, and others use whatever they are
used to (NetBeans or IDEA, perhaps). A common problem from the regular
Eclipse users is that they make changes to the Tomcat configuration files
(such as the entry for context.xml for the invoker servlet), and don't
know why it is not picked up.
Now, if I could only make projects that would be recognized by BOTH
MyEclipse and regular Eclipse as dynamic Web projects, I would be happy.
That way for each topic that I cover at Hopkins, I could distribute a
single sample project to my JHU students. Similarly, in my "real" work, I
also have clients that are split between MyEclipse and regular Eclipse,
and I want to distribute projects to them as well.
Finally, again, please remember that the invoker servlet is for testing
and experimenting only: never for deployed apps.
Cheers-
- Marty
