antioJarLocking not working
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Is there a trick to get antiJarLocking and antiResourceLocking to work
with tomcat 6? I have the following in the config:
<Host name="nix-tester.mcs.uww.edu" appBase="D:/path/to/webroots/docs"
~ unpackWARs="true" autoDeploy="true">
~ <Context path="" docBase="." debug="5" antiJARLocking="true"
antiResourceLocking="true" />
~ <Valve className="org.apache.catalina.valves.AccessLogValve"
~ directory="logs" prefix="localhost_access_log." suffix=".txt"
~ pattern="common" resolveHosts="false"/>
~ <Logger className="org.apache.catalina.logger.FileLogger"
~ directory="logs" prefix="mcs." suffix=".txt"
~ timestamp="true"/>
</Host>
There do not appear to be any error logs on anything, but the jar's are
still locked preventing redeploy.

tomcat document root?
Does that mean webapps folder? As a war or unpacked?
Would love to know what the actual error message is when its just a standard
TC setup... its a big clue ;)
The thing that made you want to do antilocking in the first place?
Aaron, I think your best bet is to get into the ruby mailing list, which
could well be the netbeans mailing list now, because I think ruby is now
Suns baby.
I think Ruby is broken...
You see, I think that antiFile locking when tomcat is using a class, and
some other app has to come in an say read an icon from a package is one
thing...
but I think if a class loader is just not letting go... thats a bug.
So say ruby has some native code... and say that is started as a static
variable... often is in a kind of singleton...
Now that thing is sitting inside tomcat, and tomcat just cant let it go...
it wants to but ruby is running and so tomcat politely waits for it...
forever.
Windows says get lost, something is busy with this folder... which you would
see if you just tried to delete that folder, after its run...
So if windows cant even delete it... no chance that TC can change it...
So I'm not sure at all if antiLocking means... I can fix a screwed webapp...
thats whats bugging me.
Would not be surprized at all that ruby has a few things set if targeting a
webapp... as opposed to running as a machine scripting tool.
Possibly theres a lib that nust not be included... or something.
Unfortunately I dont know ruby and actually hardly see it mentioned in TC's
mailing list.
Good luck...
ps what I would try do is from /manager/html
Try undeploy the old one and deploy the war from the web page...
If that works... TC does have ant script that does the same thing...
ie maybe undeploying an existing app is enough to get TC to kill the thing.
Sorry cant help more ;(

Re: antioJarLocking not working

I tried sticking the jars there - but it did not seem to make any
difference.
Let me recap on what we are trying to accomplish.
The instructor for the course is using the NetBeans 6.5 IDE for ruby
development. The students would then create a war file for deployment
on tomcat 6. The students will upload the war folder to a deploy
folder, from which a scheduled script will copy the war files into the
tomcat document root for deployment.
With just antijarlocking set, the jruby and complete jars are still
locked my tomcat, and re-deployment of the jar fails until a complete
server restart.
Antiresource locking does solve the issue of the jar's being locked,
however when set to true, whenever the application is loaded, tomcat
looks in %CATALINA_HOME%\temp-appname for the files, which does not
exist. If I manually copy files into that folder from the temp folder,
things work as expected. If we can just figure out how to get that
folder correctly populated (or get tomcat looking in the right place)
everything would be working correctly.
If anyone has any thoughts or ideas, please share!

I wouldn't normally recommend it but what happens if you just stick
those jars in %CATALINA_HOME%\lib so they are available to every web app

Hi... I have no idea, we actually run mostly on XP and I've never had a
locking issue yet... thank goodness, probably because the dev env is windows
so it wont get past go to begin with....
But maybe a good clue would be to explain what actuall happens when you dont
use antiJarLocking... ie what happens and what is the actual error when you
just run it on a stock standard TC... may wake up a few brilliant minds in
the group ;)
Thanks...

It looks like a bug in the jar. It might be using a non-portable way to

It looks like the lib is looking in the wrong place. If you haven't set an
explicit workDir then underneath %CATALINA_BASE%\work is where I would
expect the war to be unpacked and from what you say, that is what is happening.

The name of the war is temp Foo5.war. I can see folders getting created
inside of the temp folder, but the temp-Foo5 folder inside of the tomcat
6 directory is not getting created.

The reason we have docbase == appbase is because students will upload
war files to the doc base for deployment within a given subdomain.
However, that said, there is no reason why we need to set the context
path at all, since the war files all deploy to their own folder.
With antiResourceLocking turned on at the global level, I get the
following errors - Caused by: org.jruby.exceptions.RaiseException: No
such file to load -- C:\Program Files\Apache Software Foundation\Tomcat
6.0\temp-Foo5\WEB-INF/config/environment.rb
Is there any reason its going to look in temp-Foo5? If I copy files
there out of the temp folder, things work correctly, but it's unclear to
me why its looking there. Did I miss a step?

Re: antioJarLocking not working
Posted by Vikas Sharma <sh...@rediffmail.com>.
Hi,
I am also using antiResourceLocking flag in context.xml. Once the flag is
set to true, Tomcat starts exploding web application in temp directory. It
works well for me in Linux and Windows environment, but in AIX, I cannot
even start tomcat with antiResourceLocking flag set to true.
When I saw my application folder in temp (AIX box), I noticed that all files
were of zero bytes. And in the catalina logs I see lots of SAX parse
exception. Well since all files including web.xml is of 0 bytes, it starts
throwing XML parse exception.
Does anyone have work around for this problem? I am using tomcat 6.018.
