[jboss-jira] [JBoss JIRA] (JBWEB-279) Overlays do not work as expected

[Remy Maucherat (JIRA)]

     [ https://issues.jboss.org/browse/JBWEB-279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Remy Maucherat resolved JBWEB-279.
----------------------------------

    Resolution: Rejected


Servlet specification, 4.6 Resources:
The getResource and getResourceAsStream methods take a String with a leading
“/” as an argument that gives the path of the resource relative to the root of the
context or relative to the META-INF/resources directory of a JAR file inside the
web application’s WEB-INF/lib directory. These methods will first search the root
of the web application context for the requested resource before looking at any of the
JAR files in the WEB-INF/lib directory. The order in which the JAR files in the
WEB-INF/lib directory are scanned is undefined. This hierarchy of documents may
exist in the server’s file system, in a Web application archive file, on a remote server,
or at some other location.

> It is expected that the <overlay> element in jboss-web.xml has the same outcome as the overlay feature in the CLI: https://docs.jboss.org/author/display/AS72/Deployment+Overlays
> In jboss-web.xml the overlays element is not used to actually overlay existing files but to add files to a deployment. This is confusing and either this should work the same as the CLI or the documentation around the <overlay> element in jboss-web.xml should clearly state this is not the case and that we do not replace artifacts but rather 
> Attached is a proposed patch that fixes this issue.
