Seems like my celebration was a little premature.. In trying to
implement a logout action, I get the same null pointer error. So now I
can log in, but I can't log out.
Here's the logout pipeline:
<map:match pattern="logout">
<map:act type="sunRise-logout">
<map:parameter name="handler" value="foo-handler"/>
<map:redirect-to uri="foo-loginpage"/>
</map:act>
</map:match>
Stack trace is basically identical to the previous one. Is there another
Jar that the logout action may be dependent upon that needs to be placed
in the tomcat endorsed dir? I looked at the referenced line in code of
where the stack trace occurred ( at
org.apache.cocoon.sunshine.sunrise.SunRise.logout(SunRise.java:1083) ),
and it seemed like that's where it tries to destroy the session context
set during login. I'm thinking parsing error again, but what's confusing
is that if sunRise can work correctly logging in, what's the issue
logging out??
Again, thanks for the time and patience with this Cocoon newbie!
