Hi Tim, thanks for referring me to the Tomcat FAQs. That's for sure the first source of information one should read before nagging the list community with redundant questions. At least did I find therein a description how to enable CGI support.
Yet, the trivial task of identifying a running Java thread's Tomcat version seems rediculously convoluted. I assume the mentioned version script isn't much more than a mere wrapper script that puts together the a hundred chars long java invocation of some class method call that most likely is called version() along with the loading of a dozen jar libs etc. (only joking ;-) Anyway, far more than anyone can remember and type without making typos. Only problem is, my Tomcat depot on this box (randomly picked one of our HP-UX boxes, but we also have Tomcats running on Linux, AIX, Solaris (and probably Win32) doesn't seem to have bundled such a wrapper script. # swlist |grep -i tomcat hpuxwsTomcat A.4.1.29.04 HP-UX Tomcat-based Servlet Engine (ok, I concede with a properly bundled hpux depot I get a revision string that happens to be the same as the bundled Tomcat version, but that's not everywhere the case) # swlist -l file hpuxwsTomcat|grep -cF version 0 So where can I get such a version script? Hm, most likely in the official Apache Tomcat tarball distribution. Ok, I got that already for my Linux install problem (where I first thought to be required to compile from sources by Ant). Let's see if I find it there $ gzip -dc apache-tomcat-5.5.15.tar.gz |tar tf -|grep -F version apache-tomcat-5.5.15/bin/version.bat apache-tomcat-5.5.15/bin/version.sh Yup, let's see what its content is $ gzip -dc apache-tomcat-5.5.15.tar.gz |tar xf - apache-tomcat-5.5.15/bin/version.sh $ grep EXE apache-tomcat-5.5.15/bin/version.sh EXECUTABLE=catalina.sh if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then echo "Cannot find $PRGDIR/$EXECUTABLE" exec "$PRGDIR"/"$EXECUTABLE" version "$@" What the hack is catalina? Only know of an island off the coast of Los Angeles of that name, and a nice WWII water plane. But if I have the catalina.sh script anyway, and the only arg it is fed with happens to be "version" then I won't require the version script on my hpux boxes anyway. What a production... Then some of you mentioned a manager or admin webapp. Is this provided along with the basic Tomact installation, or an add-on. Well, when I run a GET on this URI on the Http10Connector according to this server's server.xml (btw, what is a Http10Connector? does it refer to the maximum bandwidth?) I only get a 404 server response. Seems there is further installation of a servlet required. # wget -O - http://localhost:8081/manager/html --16:52:07-- http://localhost:8081/manager/html => `-' Resolving localhost... done. Connecting to localhost[127.0.0.1]:8081... connected. HTTP request sent, awaiting response... 404 Not Found 16:52:07 ERROR 404: Not Found.
