Assigning a Jython variable value to an ODI variable

Question

I have to implement database cursor functionality in ODI.
For storing the returned values from database, I am using a Jython list.
The next functionality that I have to implement is as follows:
(i) For each value in the Jython list, I have to pass that value as a variable to an interface and then execute the interface
(ii) Return back to the Jython list to get the next value in it
(iii) Execute the interface for the new value from Jython list
(iv) Have to execute the interface for as many values as in the list and stop when list is over.

Hi,
Thanks for your replies.
I tried your method of using source as a query in procedure and using ODI startScen in the Target of the same procedure. But the scenario runs only once, and then stops even though the Source query returns 4 rows.
Do we have to write Source and Target in separate steps of the procedure?
Does ODI store the many records returned into some internal variables?
I need to implement a cursor functionality so what is the best approach?
Can i pass array variable value to some odi variables and do a loop?
I used a workaround....it works but dont know if that's a good way of doing things:
I retrieved all the different values that I need in a string by appending the values(this was done using Java loop).
In my next step in the procedure I call a scenario(package which has some variables and my interface), which passes this long variable from Java as <@...@>
Then in the package I use an iteration variable which is used to find out the SubString position so that I can extract the correct string to use for my Interface in the next step of the Package.
It is working fine as of now.....but things could be made simpler if I could call the scenario in the Java loop, then I wouldn't need the iteration variable etc.
