Q: Can I run Tomcat as an NT service for Bugzero (on windows)?

A: Yes, you can. Bugzero is now completely self contained and does not
   require any modifications of the classpath. So, to Bugzero, there is no
   difference whether you launch tomcat with the NT service or with the command.

Tomcat service is installed automatically during Tomcat installation if so selected.
If you have not installed the service, here is how to install one (for Tomcat 4.x):

   1. set NT environment variables:
        CATALINA_HOME=C:\jakarta-tomcat-4.1.12  (change to fit yours)
   2. launch a new DOS window, and run (all in one line):
        %CATALINA_HOME%\bin\tomcat.exe -install Bugzero-Tomcat 
        %JAVA_HOME%\jre\bin\server\jvm.dll 
        -Djava.class.path=%CATALINA_HOME%\bin\bootstrap.jar;%JAVA_HOME%\lib\tools.jar
        -Dcatalina.home=%CATALINA_HOME% -server -Xms128m -Xmx512m -Xrs -start
        org.apache.catalina.startup.BootstrapService -params start -stop
        org.apache.catalina.startup.BootstrapService -params stop -out
        %CATALINA_HOME%\logs\stdout.log -err %CATALINA_HOME%\logs\stderr.log
   3. To Uninstall Tomcat service, run:
        %CATALINA_HOME%\bin\tomcat.exe -uninstall Bugzero-Tomcat
   
   Here, the service is called Bugzero-Tomcat. Please note again that,
   this is for Tomcat 4, not 5.
