Subject war redeployment problem
Date Tue, 07 Jun 2005 13:39:30 GMT
    Sometimes while redeploing my app in tomcat I'm getting the 
following error in catalina.out :

ERROR [ContainerBackgroundProcessor[StandardEngine[Catalina]]] 
ContextLoader.initWebApplicationContext(182) | Context initialization 
java.lang.InternalError: jzentry == 0,
 jzfile = 141476144,
 total = 41,
 name = /home/serega/tomcat/webapps/pcc/WEB-INF/lib/pcc-dao.jar,
 i = 9,
 message = invalid LOC header (bad signature)
        at java.util.jar.JarFile$1.nextElement(
        at java.util.jar.JarFile$1.nextElement(

It can be cured only by restarting tomcat and happens 2 or 3 times a day 
on regular basis.

I'm using Tomcat 5.0.29 and set reloadable="true" in context.xml. I 
think  it is issue with tomcat prematurely reloading wars, but I'm not 
completely sure. I've searched tomcat-user mailing list on this error 
but haven't found anything useful (a couple of unanswered posts  - for 
example, and
I also asked this question in Appfuse mailing list 
and it looks like no one really knows how to workaround it.

Is this problem can be solved somehow or may be I should post this as a 
bug in Bugzilla ?

Thanks in advance, Sergey
