Trouble Starting OpenXAVA 5.8.1 Portlet on JetSpeed 2.3.1

Hello,

I am considering using JetSpeed 2 as the Integration Platform and OpenXAVA
for constructing the portlets in an application that I am going to write.

I have downloaded the latest version of JetSpeed 2 (2.3.1) and the latest
version of Open XAVA (5.3.1).

I was able to successfully deploy the 'MySchool' Module that comes with
OpenXAVA as a portlet on JetSpeed 2 without any errors on the console.

However, when I click on the 'Start' link for this Portlet in the Registry
Applications List in the Admin Section, it gives me the following error
and the portlet does not start.

Failed to start application : /MySchool ,
message: The App Server does not seem to be configured for remote
application lifecycle management

Again, there is no Stack Trace or Error Log in the JetSpeed Console.

I searched online for this particular error but wasn't really able to find
anything relevant.

Can someone please point me in the right direction to fix this issue?
