Question on services methods

[Foo Shyn Chung <ip...@gmail.com>]

Hi all,

This may sounds stupid, please spare me =p.

I've noticed that methods in the Services class are written as static and
i'd come across a discussion thread that talked about why it is so.
(http://osdir.com/ml/user.ofbiz.apache.org/2009-09/msg00284.html)

However, there are times that a method in the Service class is either too
long or there are common codes between 2 methods that i would like to
refactor them into using a new method. Since all the methods need to be
static, so the new smaller methods that i'm creating will be in static as
well. I wonder whether this would cause the thread-safe issue concerning
the static state of the methods?

Thanx
FooShyn

Thread safety issues come from the use of static fields in a class, not static methods.

short answer the origial design was to have individual routines so it
could be reused.
That got lost with new committers.
I dont use the SVN since I have re-factored ofbiz.
