Re: Thread safe instance variables

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Daniel,

The types of errors you will experience are difficult
to track down, that is why they associate this with the
plague. I generally pass those values through as
parameters and avoid synchronization. You
have to synchronize the whole block from setter to
return from any method that uses those variable and
expects to find your set values.

I'm still a bit hazy on thread safe stuff... Many things that I read
seem to indicate that instance variables are
generally evil and should be avoided "like the plague" (actual quote).
Seems to me that is a bit contrary to Java in
general.

If I wanted to use instance variables in a class, would I simply
syncronize the setters to insure thread safety?

Seems like beans need to be concerned with threads, as they can be run
simultaneously on a web server.

Any help would be appreciated... I guess I'm still thinking in terms of
a single path.....

thanks
