I'm trying to debug Tomcat while running as Windows Service (on Windows 7 64 bit). The Tomcat instance starts just fine, but it seems to ignore any Java options (entered through the "Java" tab on the Tomcat manager window). I know it ignores them because this line doesn't cause it to wait for a debugger, and the appropriate log line doesn't appear in catalina.log -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005 Any advice? P.S. I installed this Tomcat instance by running the Windows installer [here][1]. [1]: http://tomcat.apache.org/download-60.cgi
