Enabling JConsole JMX Remote Monitoring of Tomcat
1) Make sure your CATALINA_HOME environment variable is set to the home directory of your catalina installation
2) Create a file runCatalina.bat somewhere hat looks like:
@startlocal
SET JAVA_OPTS= -Dcom.sun.management.jmxremote
SET JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=8086
SET JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.ssl=false
SET JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.authenticate=false
SET JAVA_OPTS=%JAVA_OPTS% -XX:PermSize=256m -XX:MaxPermSize=256m
SET JAVA_OPTS=%JAVA_OPTS% -server -Xms1024m -Xmx1024m
%CATALINA_HOME%\bin\catalina run
endlocal
3) If running Vista check this out, and apply the bugfix:

I.e. need to make sure that "Everybody" has appropriate permission on the folder that JConsole uses
4) Run Catalina
5) Run jconsole (in your %JAVA_HOME%\bin directory).
6) Connect to the tomcat instancer remotely using hostname and 8086 (as defined above)

Word Useful
1) Alt f9 to toggle field codes.
2) field codes delimited by {}, but you have to menu Insert Field to get them in.
3) custom doc properties via {DocProperty "custom field name"}.
4) Margin height determines where the distinct part of the document starts and ends. This fixes header and footer height. Header and Footer determines how far from the edge of the document the header and the footer start.
5) For borders, you can set a point setting to change the distance between a border a and the text in the box
