-------------------------------------
Resolution: Invalid
> Tomcat deployment without unpacking WAR
> ---------------------------------------
>
> Key: AXIS2-2528
> URL: https://issues.apache.org/jira/browse/AXIS2-2528
> Project: Axis 2.0 (Axis2)
> Issue Type: Improvement
> Components: deployment
> Affects Versions: 1.1.1
> Environment: Tomcat 5 , jdk 4 and above on linux.
> Reporter: Sathija Pavuluri
>
> Deployment works fine when I drop my war file to /webapps and server.xml setting is:
> <Host name="localhost" appBase="webapps"
> unpackWARs="true" autoDeploy="true"
> xmlValidation="false" xmlNamespaceAware="false">
> This unpacks the war file and everything works fine.
> However, when I drop my war file to /webapps and change the unpackWARs property to
> <Host name="localhost" appBase="webapps"
> unpackWARs="false" autoDeploy="false"
> xmlValidation="false" xmlNamespaceAware="false">
> I get the axis startup error described below.

> When tomcat's unpackWARs="false" and you deploy the .war file in tomcat's /webapps this can be reproduced.
> I have been reading up on this issue and found a thread on tomcat user list that said this about running apps without unpacking the war:
> ****************************************************************************
> One thing to watch out for when running an app directly from a .war file is that if the application is trying to do any File IO where it
> tries to load resources existing within the WAR structure, it won't work if the .war is not expanded into a directory. I've noticed
> various frameworks that ignore this and continue to use File IO. These apps *will* break. See if you are getting any stack traces in
> Tomcat's log files. The webapp itself has to be written so that it can work inside a WAR.
> Most commonly, that means using ServletContext.getResource() or ServletContext.getResourceAsStream() instead of file i/o in order to read
> webapp resources.
> ****************************************************************************
> I suspect axis uses file I/O as opposed to ServletContext to load resource files.
> Most production deployments do not unpack WAR files, so having axis use the Servlet Context can definitely make things more elegant.
> Thanks.
