Hi,

I have created a new graph and when I run the graph I am getting the below error…

Can’t initialize connection DBConnection driver[null]:jndi[null]:url[null]:user[null].

Hi,

As you can see in the stack trace, the DB config file cannot be found. In order to fix this make sure the file exists on the given path.  
Also please note that version you use is obsolete as the current latest (milestone) version is 4.0 M2.

Hope this helps.
