I have one Tomcat instance that will not inventory fully. It happens to be a Tomcat 5 embedded in another product.
JMX Remoting is working properly.
The Tomcat server appears in inventory but is always unavailable and no child resources display.
The agent reports these log entries implying that everything is fine.

Here's the code that TomcatServerComponent uses to check availability:
public AvailabilityType getAvailability() { try { EmsConnection connection = loadConnection(); EmsBean bean = connection.getBean("Catalina:type=Server");
// this is necessary to prove that that not only the connection exists but is servicing requests. bean.getAttribute("serverInfo").refresh(); return AvailabilityType.UP; } catch (Exception e) { // If the connection is not servicing requests then close it. this seems necessary for the // Tomcat connection as when Tomcat does come up again it seems a new EMS connection is required, // otherwise we're not seeing EMS be able to pick up the new process. closeConnection(); return AvailabilityType.DOWN; } }
If you're seeing the Tomcat Server as red in inventory, this is most likely returning DOWN. Since your logs show that the tomcat plugin is successfully connecting to Tomcat's MBeanServer, I'm guessing that either there is no MBean named "Catalina:type=Server" registered, or that MBean is registered but does not expose the "serverInfo" attribute. I'd try using jconsole to connect to the Tomcat MBeanServer and see if either of these two things is true.

That's it! JConsole shows the MBean but not the serverInfo attribute.This embedded Tomcat must be a very old release - I found this bug fix from 2006: ________________________________
