Error instantiating servlet!!!!
hi,
I m trying to write a servlet to test one EJB. This servlet contains
only default constructor, setUp, tearDown and test method. Everything else is
properly set, I assume so, cactus.properties file and JVM properties,
but I m facing this "Error instantiating servlet' error.
Please get back to me if u have any clue regarding this ASAP.
regards,
Maniranjan Kumar

RE: Error instantiating servlet!!!!
Posted by Vincent Massol <vm...@octo.com>.
Hi,
It seems your EmptyServletTestCase1 class is a servlet whereas it should
not be. It is supposed to be a standard java class extending
ServletTestCase.
Please check http://jakarta.apache.org/cactus/howto_testcase.html
You should also check http://jakarta.apache.org/cactus/how_it_works.html
to understand how Cactus works (with WRT Redirectors, etc).
Cheers,
-Vincent
