Subject RE: NullPointer when running test
Date Mon, 01 Jul 2002 14:08:09 GMT
I had problems with authentication as well.  Instead of making the HTTP reuqest go to the login
page directly, I had it do a POST to the target servlet sending in the username and password.
 From then on, all my subsequent requests worked fine.

 then in the Page request, i request "/login.jsp".  The Thread test sequence is 5 threads
at 2 loops.  When I start the test, it appears to run fine in the console window displaying
the program output.  Below is the output of the program:

> From the looks of it, it samples the URL the first 5 times without a problem, but then
you get the NullPointer on the second set of threads.  The onlything written to the file reporter
is as follows:
