Subject Problems with contextAdmin.html under Tomcat 3.2 beta 3
Date Fri, 08 Sep 2000 10:26:32 GMT
I worked with http://localhost:8080/admin/contextAdmin/contextAdmin.html
(that is page for "Context Administration") under Tomcat 3.1 with three months and it was
fine.

But then I installed Tomcat 3.2 beta 3. It works fine, but I wanted also to work with
"Context Administration".
But during starting of http://localhost:8080/admin/contextAdmin/contextAdmin.html
displayed security window.

So I deleted elements security-constraint and login-config at web-app element at
file web.xml at directory ...\build\tomcat\webapps\admin\WEB-INF.
Then the HTML page http://localhost:8080/admin/contextAdmin/contextAdmin.html
displayed normaly.

But when I clicked button "Wiew All Contexts" displayed next error.

What am I to do?

Thanks
