Dynamic class reloading

[anyz]

I have some common classes used by various war modules on websphere 5. During development using jar file in appserver\lib\ext is hard to manage due to frequent change in classes. While using loose classes in appserver\classes folder i need to restart websphere each time class is
modified. Is there any websphere setting to reload server-level classes automatically? or any work-arround to this problem.

Thanks.
