Are struts action classes thread safe?

[Saathvik Reddy]

Hi,

Could any one justify why struts action classes are/aren't thread safe?

Thanks,

They're thread-safe if you write them to be so. Write them to not be thread-safe and they won't be.

Struts (1) action classes are not thread safe in that they are essentially singletons. Therefore non-thread safe classes and state should not be stored in instance variables.

If you don't maintain state, the classes are thread safe. (Which is what I think Bear was getting at.)
