Hope I have copied your typing style right ;-)

There is no such thing as [perfect solution] in this world!

1
Feel free to use [SingleThreadMode] as long as you don't bother about the
[performance].

2
Forget about [System ClassLoader] or [context classLoader], just to make sure
your [servlet code] is [thread safe] in [its own context].

I am going home [improving] [my English] now so next week you will [not] see
those [...] in my mail again; - )

Hi Milt,  thanks for your email :-)   but I have some questions:
0
perhaps other people have already known a perfect
way for Servlet_thread-security, but I don't know now,
and from several emails in Servlet-List, I find some
problem -- for example:
multi ClassLoders
multi Instances of the same Servlet class
...

so do you know a perfect solution for Servlet_thread-security ?
Can you post it to Servlet-List?   I will try to test it :-)

1
so I guess perhaps only  the [Servlet specification  maker -- SUN-Servlet
group ] and the [Servlet engine provider]  can give Servlet developers a
perfect solution.

2 -- so where is the [bridge]?
     a     and what is the [bridge] between [Servlet specification  maker]
            and [Servlet engine provider]?  --  I guess the interface--
SingleThreadModel
             perhaps is a good way.
     b     and what is the [bridge] between [Servlet engine provider]
            and [Servlet developer]?  --  I still guess that  the interface--
            SingleThreadModel perhaps  is a good way.


BTW, the reason that I have to use [... ] is because my English
is not good:-)

please correct me !   Thanks in advance!
