Null pointer exception when starting application

74 Views

Hi:

I had a application running fine, then i had to change some parameters in my RFC. I reimported the model, removed all the excess mapping, rebuild, deployed , restarted the server.

Then when i run the application, i get the below error.

Anyone has any idea?

java.lang.NullPointerException
