You will need to use Java 6 to run Quaestor.
Quaestor is distributed as a .war file and as a
standalone web server
(implemented using Jetty).
To install the .war file, download that and install it in
your Tomcat server in the usual way.
You can configure the server by adjusting the unpacked
.war file's WEB-INF/web.xml. Most of the
<init-param> parameters should be left alone, but
you may well need to change the persistence-directory
setting. This indicates where Quaestor should persist knowledgebases,
(when that functionality is enabled). The default value isn't terribly
useful, but should be harmless.
To start up the standalone server, download the
quaestor-standalone-x.x.jar file (of a suitable version
number), and either double-click it (if that's appropriate for your
OS), or start it with a command like:
% java -jar quaestor-standalone-x.x.jar
As with the .war file, there is very little to
configure in the standalone server. To change the location of the
persistence directory, give a value for the
persistence-directory property when you start the server,
by giving the -Dpersistence-directory=/path option to the
java command.
