Hello,
I run Tomcat 6.0.x as a service on Windows 2003, using Sun JDK 1.6. I
was trying to use the jstack program, part of the JDK, to get a stack
dump from Tomcat/Java on my server. However, I ran into a problem. First
of all, Tomcat on Windows seems to "hide" the JVM instance. Java doesn't
show up in my process listing. I tried running jstack against the
Tomcat PID but it errored out.
Any idea how to make jstack work with Tomcat running as a service on
Win2k3?
I can't answer your question, but a look here might provide a clue :
http://commons.apache.org/daemon/procrun.html
That seems to be the way in which Tomcat is now implemented under
Windows. Versions prior to 5.5 used to have a structure similar to the
Unix version, with startup.bat and catalina.bat invoking Tomcat via Java,
but that seems to have changed nowadays.
Also, if it might help somewhat : open a command window and navigate to
the Tomcat/bin directory. Then, instead of running tomcat as a service,
just enter the "tomcatx.exe" command (where x is probably 6 in your case)
(not the tomcatxW.exe). That will run Tomcat in the command window, maybe
easier for you to figure out what is going on.
Not for me though.
Addendum :
I just had another look at the Tomcat site. For version 5.5, there are 2
downloads for Windows : one is a zip, the other an msi installer.
I must have in the past downloaded and installed the msi.
I downloaded the zip version now, and that one seems to contain the usual
startup.bat and catalina.bat files, in addition to the Win32 tomcat5 and
tomcat5W executables.
Maybe the .bat files allow to start Tomcat in the "traditional" way, via
Java etc.. ?
------------------------------------
As a Service the PID is TomcatX
From the start.BAT its JAVA
The easiest way to get the PID is to type
netstat -noa
Its the one next to the port you on...
On windows... you install your service version EXE
Then you download the zip version and copy the missing BIN scripts across...
then you have all the files
If you need thread dumps....
Start TC from the BAT file.....
When you need a dump... press ctrl + break from term window... easier than
Jstack...
Andre is right..... as a service Tomcat appears under the non normal java...
because its started from a windows service... not launched as a normal java
process.
