Monitoring TomCat on SolarWinds DPA server

Has anyone setup the TomCat SAM template to monitor TomCat on a SolarWinds DPA Server?

I am testing out the TomCat SAM template against DPA before we start deploying the template to other Production TomCat Servers.  I did setup a userid and password in the tomcat-users.xml file and rebooted.  No luck.

Not even able to pull up the /manager/html page on the DPA server.

Any ideas?
