For this you need to run the  tomcat6w  application that is part of the standard Tomcat distribution in the  bin  directory  E g  for windows the default is  C  Program Files Apache Software Foundation Tomcat 6 0 bin tomcat6w exe   The  tomcat6w  application starts a GUI  If you select the  Java  tab you can enter all Java options    It is also possible to pass JVM options via the command line to tomcat  For this you need to use the command    lt tomcatexecutable gt    US   lt tomcatservicename gt    JvmOptions   lt JVMoptions gt     where  tomcatexecutable  refers to your tomcat application   tomcatservicename  is the tomcat service name you are using and  JVMoptions  are your JVM options  For instance    tomcat6 exe    US  tomcat6   JvmOptions  -XX MaxPermSize 128m

As Bhavik Shah says  you can do it in JAVA OPTS  but the recommended way  as per catalina sh  is to use CATALINA OPTS       CATALINA OPTS    Optional  Java runtime options used when the  start                        run  or  debug  command is executed                      Include here and not in JAVA OPTS all options  that should                     only be used by Tomcat itself  not by the stop process                      the version command etc                      Examples are heap size  GC logging  JMX ports etc       JAVA OPTS        Optional  Java runtime options used when any command                     is executed                      Include here and not in CATALINA OPTS all options  that                     should be used by Tomcat and also by the stop process                      the version command etc                      Most options should go into CATALINA OPTS

If you start tomcat from startup bat  you need to add a system variable  JAVA OPTS as name and the parameters that you wants  in your case     -agentpath C  calltracer jvmti calltracer5 dll traceFile-C  calltracer call trace filterFile-C  calltracer filters txt outputType-xml usage-uncontrolled -Djava library path C  calltracer jvmti -Dcalltracerlib calltracer5

Set it in the JAVA OPTS variable in  path to tomcat  bin catalina sh  Under windows there is a console where you can set it up or you use the catalina bat   JAVA OPTS -agentpath C  calltracer jvmti calltracer5 dll traceFile-C  calltracer call trace filterFile-C  calltracer filters txt outputType-xml usage-uncontrolled -Djava library path C  calltracer jvmti -Dcalltracerlib calltracer5

After checking catalina sh  for windows use the  bat versions of everything mentioned below       Do not set the variables in this script  Instead put them into a script     setenv sh in CATALINA BASE bin to keep your customizations separate    Also this      CATALINA OPTS    Optional  Java runtime options used when the  start                        run  or  debug  command is executed                      Include here and not in JAVA OPTS all options  that should                     only be used by Tomcat itself  not by the stop process                      the version command etc                      Examples are heap size  GC logging  JMX ports etc   So create a setenv sh under CATALINA BASE bin  same dir where the catalina sh resides   Edit the file and set the arguments to CATALINA OPTS  For e g  the file would look like this if you wanted to change the heap size  CATALINA OPTS -Xmx512m   Or in your case since you re using windows setenv bat would be  set CATALINA OPTS -agentpath C  calltracer jvmti calltracer5 dll traceFile-C  calltracer call trace filterFile-C  calltracer filters txt outputType-xml usage-uncontrolled -Djava library path C  calltracer jvmti -Dcalltracerlib calltracer5   To clear the added options later just delete setenv bat sh
