In this case, all u have to do is modify the processGridletReturn() 
function (as called in GridUserFailureEx01.java class) to do what u 
want. This function is called when a gridlet is received, and 
essentially it collects statistics about the just received gridlet. Now, 
u have to modify it to submit the next gridlet.

Besides, u also have to modify the body() function, because by now it 
submits a gridlet when a GRIDLET_SUBMIT event. Now, u remove this part 
and submit gridlets as I mentioned above.

Hope this helps.

Agustin
