Summary: ProxyDirContext does not handle overlays when caching is turned off
(Servlet 3.0 spec incompatibility)
Key: JBWEB-273
URL: https://issues.jboss.org/browse/JBWEB-273
Project: JBoss Web
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Affects Versions: JBossWeb-7.0.15.GA
Reporter: Phil Phil
Assignee: Remy Maucherat
We have a Servlet 3.0 based web application that makes use of the 'modular webapp'
functionality. In particular, we utilize the ability to place resources in each
module's {{META-INF/resources}} (as defined in section 4.6 of the Servlet 3.0 spec).
We have noticed that {{org.apache.naming.resources.ProxyDirContext}} does not respect
overlays when caching is turned off. Meaning, it fails to find resources defined in a
module's {{META-INF/resources}} directory when caching is turned off. This is
documented behavior in the javadoc (notice: "when caching is enabled")
{code}
* Proxy Directory Context implementation. This implementation looks up the
* resources from a main DirContext, with secondary DirContext allowed
* to provide overlays for the main one, when caching is enabled.
{code}
I would like the ability to turn off caching, while still honoring the overlays. And
since the Servlet 3.0 spec does not mention the ability to ignore overlays when caching is
disabled, I think this is a case where jboss is not adhering completely to the spec.
Specifically, our UI developers would like to turn off caching of static resources (by
setting {{cachingAllowed="false"}} in {{context.xml}}) so that they can do rapid
UI development on a running server by just modifying files in the overlays w/o having to
redeploy.
Note that the {{list*}} methods already honor the overlays when caching is off. However,
other methods such as the following do not honor the overlays when caching is off.
* {{lookup*}}
* {{getAttributes}}
In general, it seems like the overlay concept is only partially implemented in
ProxyDirContext even when caching is turned on. For example, the {{search}} methods do
not look in the overlays. This seems like it does not adhere to the Servlet 3.0 spec
either.
