Description of problem:


Version-Release number of selected component (if applicable):
JON 3.0.0.CR2

How reproducible:always


Steps to Reproduce:
1. setup and inventory tomcat
2. go to tomcat's connection settings in JON UI
  
Actual results:

If you check agent's log, you'll find NPE, even before step #2

WARN  [ResourceContainer.invoker.daemon-18] (jboss.on.plugins.tomcat.TomcatServerComponent)- Could not establish connection to the Tomcat instance [11] times for resource [C:\Program Files\Red Hat\Enterprise Web Server\share\apache-tomcat-6.0.32]
org.mc4j.ems.connection.EmsConnectException: Could not connect [null] java.lang.NullPointerException

In JON UI (after setp #2) I get error welcome message

The following connection settings have invalid values: [Manager URL]. The values must be corrected before the settings can be saved.

Right next to the field, there is a hint of default value.

Expected results:
Default Manager URL should be predefined. That would mean NPE in agent log disappears.
