Issue:
I am trying to configure the tomcat probe to monitor my Spectrum OneClick servers - it fails with error message:

"Naming problem, reason: java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: non-JRMP server at remote endpoint]: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: non-JRMP server at remote endpoint]"


and


"Unable to connect : xxxxxxx.xxxxx.co.za
i18nPDS desc value: Lost connection to the server?
i18nPDS resourcename value: xxxxx.xxxxx.co.za
Err token value: as#application.tomcat.resource_critical_error
resourcealarm: D, severity=5, message==The resource xxxx.xxxx.co.xxxis not responding, subsystem=1.1.14.4.1, suppressionid=spectroweb1.shoprite.co.za, source=spectroweb1.shoprite.co.za, alarm already scheduled to be sent."

When i try to use the Actions/Test function, it shows me ping error to the target server, but if i go to the command line of the robot server and manually ping the trget IP, I dont get a ping error: both of these servers are located in the same sub-net.

 
Environment:
Robot server v7.93
Java version 1.8.0_102 

Java home C:\Program Files (x86)\Nimsoft\jre\jre8u102 
Java VM Oracle Corporation 

OS name Windows Server 2012 R2 

Tomcat probe: v1.3 

UIM v8.5.1 on a robot server running 

CA Spectrum OneClick server 
Operating system: Red Hat Enterprise Linux Server release 7.2 (Maipo) 
Cause:
The possible causes of this issue can be:  1. Bad port defined in the connection details:  2. Use of user name and password: must be blank 3. Spectrum server is missing the following lines:  jvm_opt=-Dcom.sun.management.jmxremote  jvm_opt=-Dcom.sun.management.jmxremote.port=8008  jvm_opt=-Dcom.sun.management.jmxremote.authenticate=false  jvm_opt=-Dcom.sun.management.jmxremote.ssl=false   In windows: C:\win32app\Spectrum\tomcat\bin\OneClickService.conf   In linux $SPECROOT/tomcat/bin/catalina.sh    Example of wrong configuration: User-added image
Resolution:
1. the port in the connection details should be 8008 (JMX default port)
2. Do not ser any username and password: must be blank
3. Verify the Spectrum server contains the following keys:

In windows:
C:\win32app\Spectrum\tomcat\bin\OneClickService.conf 

In linux
$SPECROOT/tomcat/bin/catalina.sh 

jvm_opt=-Dcom.sun.management.jmxremote 
jvm_opt=-Dcom.sun.management.jmxremote.port=8008 
jvm_opt=-Dcom.sun.management.jmxremote.authenticate=false 
jvm_opt=-Dcom.sun.management.jmxremote.ssl=false
