Shortly :
If you are local, then you can use the "Local process" option in jconsole.
Otherwise : as far as I remember, the jmx connection really uses 2 ports, not only the one
you obviously connect to. And that second port is random, which is what makes it difficult
to connect through a firewall or so.
Maybe it is that second port that is blocked in your case ?
Have another look with tcpview while you are trying to connect, if you do not see some new
LISTEN port appear during the connection attempt.

Hi,
I am having a problem connecting to Tomcat 6 running as a service on Windows
Server 2008 R2. Here are the details of my setup.
32 Bit JDK 1.6._23
64 Bit Windows Server 2008 R2
My jakarta service log shows that I am setting the jvm properties to turn on
jmx remote access to the JVM
[2010-12-22 23:22:21] [447 javajni.c] [debug] Jvm Option[6]
-Dcom.sun.management.jmxremote

I am running jconsole on the same machine that is running tomcat so I am not
trying to connect remotely and should
not have any problems with ports I even turned off the windows firewall on
the machine to make sure it was not getting
in the way
systernals tcpview shows that tomact6.exe is listening on port 8999
I am running tomact6 service as the user pmtomact
I am running jconsole as the user Administrator
on the jconsole I tried localhost:8999 and it tries to connect for a while
then reports that it can can not connect.
I tried running tomcat as user administrator just starting from the
startup.bat with the proper jmx paramters and it does not work either.
I tried running jconsole as pmtomcat user still no luck connecting
I tried creating a directory under
C:\Users\pmtomcat\AppData\Local\Temp\hsperfdata_pmtomcat and checked that
the directory was writable by the pmtomcat user still it does not work.
Any ideas of how I can troubleshoot this problem, it is driving me crazy?
