All,
Referring to a classic Tomcat log like the one below :
Would it not be a good idea for Tomcat, when it starts, to print a first
line to its main logfile, similar to what Apache httpd does :
[Tue Apr 01 18:00:02 2014] [notice] Apache/2.2.12 (Linux/SUSE)
mod_ssl/2.2.12 OpenSSL/0.9.8j-fips mod_jk/1.2.26 mod_perl/2.0.4
Perl/v5.10.0 configured -- resuming normal operations
I mean, for Tomcat, a line with it's own version, the Java version, the
APR version if used, the host OS if available etc..
All these things that we usually ask the posters to this list to
provide, and which can be obtained via the "version.sh|bat" script in
tomcat/bin.
In at least 50% of the cases, it would at least save us from having to ask.
And actually running the "version.sh|bat" script on the server (or any
command-line for that matter) may not necessarily be easy for everyone
who has a problem.
Sample current log :

+1 for this
I can think of several (OK, many) mailing list threads where having this
knowledge would have saved lots of time and effort.
. . . just my (lazy) two cents.
