Ivan,
First off, I don't know too much about Cactus testing. Where is
ServletTestRunner coming from?
I tested
com.jcorporate.expresso.services.controller.tests.LoginControllerTest
and com.jcorporate.expresso.services.controller.tests.DBMaintTests and
they seem to work fine. Did you:
1. Uncomment the servlet definitions and servlet mappings for
ServletRedirector and JspRedirector in web.xml?
2. Set the correct cactus.contextURL (which would be
('http://localhost:8080/emaria' in your case) in cactus.properties in
the root of your WEB-INF/classes
3. Start mysql & Tomcat (or whatever your servlet container is)
4. Run your ControllerTest under JUnit (I use Eclipse as my IDE, and I
can do this directly from Eclipse - I assume IntelliJIdea has similar
capability)
Try it on LoginControllerTest and DBMaintTests and let us know the
results.
