HttpServlet and Static Methods

[Eric]

I have a threadsafe servlet, but if I add a call to a Static method in
another class, will my servlet still be threadsafe?

I know if I Synchronize it, it will be, but I would rather not do such.

Thank you in advance for any help.

A quick answer. It depends on the implementation of that static method:

If that static method accesses static data (either static data directly or
cached instance-data) in a thread-unsafe way, then you can not call that
method without sacrificing your own method's thread-safety.
If that static method purely/only acts on the parameters you provide it when
you call it (i.e. it uses only stack-variables and instances it creates
while it's running), then there is no problem.

So, look at the documentation of that static mehotd. If it claims to be
thread-safe, no problem. If not so, call it at your own risk..
