Null Pointer exception in retrieving value from web.xml

Hi,
 
I am using Cactus 1.6.1 to test Servlet class. I am testing in weblogic6.1 app server. The method called for testing calls another servlet class which retrieves parameter value defined in web.xml file.
Here Cactus returns Null Pointer exception. what can be the reason?
 
Thanks
 
Radha

2 things:

1/ Are you sure you've called "myServlet.init(config)" in your test, as

2/ If you need more help you'll need to show us the full stack trace of the
error...

No! Cactus is about *unit testing* not about functional testing. We're not
doing black box testing but white box testing. 

Think about how you unit test any POJO. You instantiate the class and then
call the method do test. Same for Cactus.

If you wish to write functional tests, do not use Cactus. You'll find better
tools elsewhere.

what are the different possibilities of calling a servlet class

Posted by radha devi <ka...@yahoo.com>.

Hi

To test a servlet, do I always need to create an instance of the servlet or is there any other way to call the servlet. 
 
Is there way to call the servlet class through URL?
 
Thanks!

Hi Radha,

2 things:

1/ Are you sure you've called "myServlet.init(config)" in your test, as
explained on
http://jakarta.apache.org/cactus/writing/howto_testcase_servlet.html

2/ If you need more help you'll need to show us the full stack trace of the
error...
