Issues graphing Composite data from JMX operations using ZenJMX

Having issues graphing data using operations from JMX.

Our application has its own mBeans. The Datasource is setup with operation, parameter types and parameter input. The operation returns a composite data which has name, value, creationTime and updatedTime. There is supposed to be only one composite object returned. I have a datapoint setup to use value. Zenoss is not returning any error events. However, the graph always shows nan value.

How do I debug this issue Is there something that that I may need to graph the data. Is there an example that I can find that where jmx operations are being used currently

I have used the following link http://wiki.zenoss.org/ZenPack:Java_2_Platform_Standard_Edition_(J2E) without much success.
The operation that I am trying to use and the composite value is available via jconsole. The following link shows what I am trying to access: https://www.dropbox.com/s/az7u9uc6kd3mosv/jconsole.JPGdl=0

Please help me plot the datapoint in zenoss.

I have updated the above with more details to get a response.
