For this one:

I wanna try to avoid using Type conversion.
Um, why?
This didn't work either:
int task_id = Integer.parseInt(
parameters.get("task.id").toString()) ;
parameters.get("task.id").toString() evaluates to (java.lang.String)
[Ljava.lang.String;@434ff9
Do I have to use type conversion even for primitive
types?
Any idea?
Yes, look up what the parameters map actually
contains.
Normally when reporting an error like this you'd show
the typecast exception you're getting, which should
provide a clue as to why it isn't working, as an array
of a type can't be converted to a single instance of a
type.
There are quicker ways of finding answers to these
questions than posting to the group!
Like what. Please tell me a place where I can get this resolved. :) You
think I didn't look ? Sometimes programmers get stuck with a problem
that looks simple to others. No one knows everything, Dave !
