Is it possible to delete a jar file from ../WEB-INF/lib when Tomcat is running?

Hi All,

Is it possible to delete a jar file from ../WEB-INF/lib when Tomcat is
running? I tried to delete the jar from 'lib' after putting following entry
in catalina.policy:

grant codeBase "file:${catalina.home}/webapps/abcd/WEB-INF/lib" {
permission java.io.FilePermission "read, write, delete";
};

but it was giving following error:

 java.io.FileNotFoundException:
C:\AppServer\Tomcat\apache-tomcat-6.0.10\webapps\
abcd\WEB-INF\lib (Access is denied)...
