[mbalaji2000]

Hi
I am trying to use the ACTIVITI api in MSSQL SERVER 2008, while i try to use the activiti-explorer application's DemoDataGenerator bean im getting the below error in a particular senario.
If i run this application as such im not getting any error and its able to run.
Senarios when i get this error.
If I try to add the demo apps xml file and other needfull files with an existing application im getting this below error.
Am not sure where am missing or going wrong.
Error
