Tomcat 3.1 on WinNT/98 needs contect_log

["BAZLEY, Sebastian" <Se...@sema.co.uk>]

I've downloaded Tomcat 3.1 and installed it on both WinNT SP4 and Win98 SE.

It works very well, but requires a minor change to server.xml: there needs
to be an entry for context_log, such as:

    <Logger name="context_log" 
            path="logs/context.log"
            customOutput="yes" />

Without this, the run command fails with:

[The above is on WinNT. I think the output is similar on Win98, but I don't
have the log.]

C:\jakarta-tomcat\bin>java -version
java version "1.2.1"
Classic VM (build JDK-1.2.1-A, native threads)

I'm afraid I don't know why this is; I just made a guess and added the
context_log entry in the hope of getting extra logging output to try and pin
down the error - it certainly worked!

I have also used the same version of Tomcat on AXP/VMS 7.2-1; it does not
seem to need the context_log entry. I don't know why this should be either!

But at least the fix is simple (assuming that adding the extra context_log
tag does not have any adverse side effects on other systems).
