Hi,

I have set up Tomcat 4.1.27(with jdk 1.3.1) as a service on a Win2k machine using the following script -

tomcat -install "Apache Tomcat" "%JAVA_HOME%\jre\bin\server\jvm.dll"
-verbose:gc -Djava.class.path="%CATALINA_HOME%\bin\bootstrap.jar"
-Djava.endorsed.dir="%CATALINA_HOME%\common\endorsed"
-Dsun.io.useCanonCaches=false -Dcatalina.home="%CATALINA_HOME%" -start
org.apache.catalina.startup.BootstrapService -params start -stop
org.apache.catalina.startup.BootstrapService -params stop -out
"%CATALINA_HOME%\logs\stderr.log"

I wanted to see the GC ouput, so, I added the -verbose:gc flag. When I see
the registry, I can see this has gone in as a JVM option. But in the log
file, I cannot see any GC output at all. When I try the -verbose:gc in the
console mode(putting it in the catalina.bat file), I can see the GC output
on the console. Am I doing it correctly? If not, what am I doing wrong? Where does Tomcat put the GC output?

Thanks
-Manoj Pooleery.

is the jvm option on it's own line in the registry?

like:

JVM Option Number 0 -> -verbose:gc
JVM Option Number 1 -> etc, etc...

oh.. and is JVM Option Count the correct count ?

Yes, I have specified the number of JVM options correctly. Here are the registry values -


In the stderr.log, there is everything except the GC output. Right now, I'm literally Does Tomcat put the GC output in a separate file? If so, where?

Thanks

I have run into several problems with Tomcat 4.1 logging when it is ran as a service. I have discovered that if you use the org.apache.catalina.startup.Bootstrap for your start and stop classes my issues went away. This may solve your issues as well.

You can change the start and stop services in your registry:
hkey_local_machine\system\CurrentControlSet\Services\Apache Tomcat 4.1\Parameters\[start class & stop class]

Hope this helps,
Chow
