Re: Making Action object as singleton

I'm pretty sure that action objects are created only
once by the server.

this question may have been answered before if this is
not what you are looking for.

That's okay, everyone's learning around here, myself included.  :)

It's good that you were planning your Action as a Singleton, though, because
that's exactly how Struts treats all Action classes.  Therefore, as you
mentioned, you cannot have class-level member variables (unless they are
static or intended to be shared across sessions) and must pass values
through method calls instead.  Any state variables should go into the
ActionForm associated with the Action instead, or into the HttpSession if
this is not feasible for some reason.

peace,
Joe

[Bhattad, Nilesh]

Thanks for your clarification.
I'm not yet much familiar with Struts framework. And I didn't know that
Struts take care of making Action object as a Singleton. May be I should go
back and study Struts in detail before implementing it!

Thanks again.

Making Action object as singleton

[Bhattad, Nilesh]

Hello

I have an Action object which is common for all JSP pages. It doesn't have
any object level variable in it. What are all the advantages/disadvantages
of making Action object as a singleton?

Thanks in advance !!
