runtime problem

I am new to java programming.  So I hope my question isn"t to trivial.  I
have a program that reads an IFS file, then does some updating to a
database.  This program worked up until last week.  I wrote program in WDSC
works fine in the development studio,  moved the class to 400 gives this
error any thoughts.  Any help would be appreciated.
Here is the error
