Exploded war folder becomes corrupt

[Kenneth Westelinck <ke...@gmail.com>]

Dear list,

I have an application (ApplicationA) running on Tomcat 6.0.16. Occasionally,
when Tomcat is restarted, the contents of the folder where the exploded war
resides becomes corrupt. I.e. jars that can be found underneath
<tomcat>/webapps/ProjectA/WEB-INF/lib are removed, resulting in numerous
ClassNotFoundExceptions.
Deleting the exploded war folder and restarting Tomcat resolves this issue
... but this is not an ideal situation of course. This error ocurs on my
client's machine. I was not able to reproduce this on our local development
machine. The client's machine is running Windows XP, SP3, no virusscanner.
Is there anyone else on the list that has seen this behaviour?

Many thanks in advance.


regards,

Kenneth

Sorry for some strange characters, correct line is:

unpackWAR="false" antiJARLocking="true" antiResourceLocking="true"

Please read http://tomcat.apache.org/tomcat-6.0-doc/config/context.html

Windows OS uses different file locking (it applies to jar files) 
mechanism that e.g. Linux. Sometimes it makes problems with 
undeploying/removing application.

I had once similiar case. Struts/hibernate application, there're many 
notes, that due to some reasons Tomcat is unable to completely undeploy 
such application. Result is that it's impossible to completely remove 
application's folder. I have added following attribues to 
|META-INF/context.xml and it helped:

||unpackWAR="false" ||antiJARLocking="true" ||antiResourceLocking="true"
