Hi -
I am working with an application which was written on AAOD 6.0 and we are trying to upgrade to 7.2.1. We are seeing an HTTP 500 response when we try to run with the Application Simulator which seems to stem from a NullPointerException in Entry.service:

SEVERE: Servlet.service() for servlet Start threw exception

java.lang.NullPointerException

Grateful for any assistance you can provide,

The error doesn't make sense. Do you see any problem in the Problems tab in Eclipse?

There are currently no errors on the Problems tab.

Did you see any error during the import? The project seems not been upgraded properly. Essentially, it is missing the following in the web.xml file:

<context-param>
<param-name>runtime-nature</param-name>
<param-value>speech</param-value>
<description>Application nature, speech or message</description>
</context-param>

Thanks, that helped me identify a process error on our side that was losing the changes to web.xml after the Upgrade ran.
