Newbie question: how do you force tomcat to restart?

[mboswort]

There's no tomcat in my task manager b/c this computer's not the server - I'm on a company computer. Tomcat seems to be crashing and I want to shut it down and restart it. What do I do? Please help.

There will never be a "Tomcat" in your task manager, because Tomcat is run inside a JVM, which shows in your process list on Win32 as "java.exe"

You should stop and start it as you do normally ...

Tomcat is running on a unix server. My computer is not that server. I was told to "sudo tomcat" and then run the shutdown script in order to shut the server down. How do I do this? I'm not acquainted with the sudo command on unix.

 

[sedj]

Thats a question for the linux forum really ...

But, if Tomcat is running as the user "joe" :

su - joe

Then enter the password for that user.

Then run the shutdown script. If Tomcat is installed in /usr/local/tomcat :

/usr/local/tomcat/bin/catalina.sh stop
pkill -9 java

Thanks.

I ran

su -u tomcat ./shutdown.sh

and got:

./shutdown.sh: /proj/bo/apps/db-dev/apps/jakarta-tomcat-5.0.28-bo/bin/catalina.s: bad interpreter: No such file or directory
./shutdown.sh: line 38: /proj/bo/apps/db-dev/apps/jakarta-tomcat-5.0.28-bo/bin/catalina.sh: Success

I then tried accessing the tomcat server from a browser, and it was still up. So the shut down must not have worked.

I run shutdown again, and now I get this message:
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 18134; nested exception is:
java.net.BindException: Address already in use

 

[sedj]

Do :

pkill -9 java

OK, thats fine then - you've killed off tomcat successfully by the looks of it.
The other java process looks to be some other app.

the server went down. that's good. i'm trying to restart it now.

 

[mboswort]

i was hoping that restarting it would fix this problem, but for some reason a handful - about 1/2 - of the webapps suddenly can't start. when i run the admin program, and examine the contexts for any programs that are not running, there is always an error saying that an attribute could not be retrieved.

 

[sedj]

So what are the errors in Tomcat's logs ?

also, here's something that is really weird and might be related.

in my catalina.properties file, common.loader is originally:
common.loader=${catalina.home}/common/classes,\
${catalina.home}/common/endorsed/*.jar,\
${catalina.home}/common/lib/*.jar

Then, when I append one line at the end:
common.loader=${catalina.home}/common/classes,\
${catalina.home}/common/endorsed/*.jar,\
${catalina.home}/common/lib/*.jar,\
${catalina.home}/common/lib/ext/*.jar

Suddenly the tomcat server is missing like 5 web apps and, if u look in the admin program, many more contexts. How weird is that...

 

[mboswort]

btw, thanks for the pkill tip. very useful

Looks like the "demo" webapp is missing some JSF classes : javax/faces/el/VariableResolver

[mboswort]

sry, but what does this mean? "javax/faces/el/VariableResolver" ...

 

[sedj]

Looks like the "demo" webapp is missing a .jar file which contains the class ""javax/faces/el/VariableResolver", which by the sounds of it is a JavaServerFaces framework class
