problem in upgrading spring 1.4.5 to spring 2.5.5

[bharu]

Hi all,
I am confident that i am going to get this issue resolved by the great people who are here in this community..
Here it goes:

I am having an application that is running in spring 1.4.5. I tried to upgrade it to spring 2.5.5. There were many compatible issues while building. One among such is RowMapperResultReader class is removed in spring 2.5.5. I was able to resolve all the build errors.

I am using JDK1.6 and Tomcat6.0.18

But i having deployment issues while starting the server.
"servletContext must not be null" which is the error i get while deploying. can any one peep into this issue. Is the loading the servletContext different in spring 2.5.5. Can any one help us the flow how the application context get initialized in spring 2.5.5.

The same code works fine in spring1.4.5 but we face problems only in 2.5.5.

In our application we have the web.xml along with the businesstierContext.xml which contains the busness level xml's just for modularity in the application.

I have given here my web.xml, businesstiercontext.xml and one of my module level xml which is responsible for the below deployement error.


Error log while deploying:

Hi bharu,

FYI: you have posted to the SpringSource dm Server "Application development and deployment" forum.

You will likely get better assistance if you post your Spring MVC related questions to the Web forum.

Regards,

Sam
