Directories in Tomcat 5.5\temp

Hi

I'm developing and testing application (Tomcat 5.5\webapps\myapp)
using Tomcat 5.5 on Windows XP.

After some times, I notice that there are directories created in Tomcat 5.5\temp
1-myapp, 2-myapp, 3-myapp and etc.

These directories are there even after I restarted Tomcat.

Can anyone explaines why these directories are created?
and why these directories are not being clean-up by Tomcat?

Deployment with the tag option?

Use of the anti-locking attributes?

I *think* the antiResourceLocking in tomcat may cause this if configured 
in your <Context ...> element.  Those with better knowledge might want 
to comment further.  Last I know the webapp is copied/expanded to either 
temp or work when it's enabled.

You may read more about the log4j error at
http://marc.info/?l=log4j-user&m=120897082320333&w=2

So, that seems to be a normal behaviour in Tomcat.

Maybe we should conclude that this is an expected side-effect of using
antiResourceLocking?

Not likely to be the problem, but I can't be sure.

This certainly isn't the cause; that's just because you don't have APR
installed.

Re: Directories in Tomcat 5.5\temp

Posted by hezjing <he...@gmail.com>.
The Monitor Tomcat is one of the menu items created by Tomcat installer.
You can find it from Windows Start -> Programs -> Apache Tomcat 5.5 ->
Monitor Tomcat
where it's target is pointing to Tomcat 5.5\bin\tomcat5w.exe.

My application is using log4j release 1.2.15 and now, I noticed the
following suspicious error in stdout_20080423.log (appeared after
Tomcat is stopped),

    log4j:ERROR LogMananger.repositorySelector was null likely due to
error in class reloading, using NOPLoggerRepository.


and this INFO message in catalina.2008-04-23.log,

    23-Apr-2008 21:06:31 org.apache.catalina.core.AprLifecycleListener
lifecycleEvent
    INFO: Failed shutdown of Apache Portable Runtime


I'm not sure if the above is causing the abrupt termination of Tomcat?

Unless you really, really need that, I'd turn it off.

I don't know what that is, but I suspect it's causing an abrupt
termination rather than an orderly shutdown.  You should be using either
the shutdown script or the tomcat5w.exe program to stop the Tomcat
service.

The exact same steps (using the tomcat5w.exe program to start/stop the
service) work fine for me, and result in an empty temp directory.

Re: Directories in Tomcat 5.5\temp

Yes, I'm using antiResourceLocking as shown in Tomcat 5.5\webapps\myapp\META-INF

<Context reloadable="true" antiJARLocking="true" antiResourceLocking="true">
<Manager className="org.apache.catalina.session.PersistentManager"
saveOnRestart="false" />
</Context>


I stopped Tomcat service normally (using Monitor Tomcat).
The following are the steps I performed,

1) Stopped Tomcat 5.5 service.
2) Delete all files in Tomcat 5.5\temp\.
3) Started Tomcat 5.5 service.
4) Tomcat created Tomcat 5.5\temp\0-myapp\.
5) Opened IE and load http://localhost:8080/myapp, then closed IE.
6) Stopped Tomcat 5.5 service.

7) Tomcat 5.5\temp\0-myapp still exists

You must have antiResourceLocking set to "true" for those (or possibly
all) webapps.  Doing so will indeed cause Tomcat to use the temp
directory; however, with a normal Tomcat shutdown, these will be
removed.  Are you terminating Tomcat abnormally, or are you just poking
around while it's running?

Hi Chuck

Hmmm ... I don't think my web application is explicitly writting
anything into the directory.

When I look further into these directories, they contain the same (and
only) JAR files of my web application,
e.g. Tomcat 5.5\temp\0-myapp\WEB-INF\lib\*.jar
Tomcat 5.5\temp\1-myapp\WEB-INF\lib\*.jar

Your webapps are creating them.

Tomcat merely provides the workspace for the webapps; usage of it,
including any desired cleanup, is up to the webapps.
