Found service in registry from name InstanceManagementService/listAllInstances: null

[ratha]

Hi all,

When i try to get a XMLHttp request from ODE server to view 
instances(through java script) I'm getting exception like 
Status:500(internel server error) and my tomcat console states as follows,

DEBUG - GeronimoLog.debug(66) | Checking for Service using target 
endpoint addre
ss : /ode/processes/InstanceManagementService/listAllInstances
DEBUG - GeronimoLog.debug(66) | Found service in registry from name 
InstanceMana
gementService/listAllInstances: null


I pass the 
URI=http://localhost:8080/ode/processes/InstanceManagementService/listAllInstances.
Is there error in my URI or something else?

Thanks,
-ratha.
