JAX-RS application Failed to load and run, when using jersey Application
servlet class defined inside the web.xml (v3).
------------------------------------------------------------

Key: JAX_RS_SPEC-330
URL:
http://java.net/jira/browse/JAX_RS_SPEC-330
Project: jax-rs-spec
Issue Type: Bug
Components: model api, server
Affects Versions: 2.0-pr
Environment: Windows 7 Professional SP1.
GlassFish 4_b69
Reporter: Mohamed Taman
Priority: Blocker
When I was testing the *section 2.3.2 Servlet* for the first part which
dictates:
{quote}
• If no Application subclass is present, JAX-RS implementations are
REQUIRED to dynamically add a servlet and set its name to
javax.ws.rs.core.Application
and to automatically discover all root resource classes and providers which
MUST be packaged with the application. Additionally, the application MUST
be packaged with a web.xml that specifies a servlet mapping for the added
servlet. An example of such a web.xml file is:
1 <web-app version="3.0" xmlns="
http://java.sun.com/xml/ns/javaee"
2 xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
3 xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee
4
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
5 <servlet>
6 <servlet-name>javax.ws.rs.core.Application</servlet-name>
7 </servlet>
8 <servlet-mapping>
9 <servlet-name>javax.ws.rs.core.Application</servlet-name>
10 <url-pattern>/myresources/*</url-pattern>
11 </servlet-mapping>
12 </web-app>

The following JAX-RS2 app bellow was failed to be registered and run by the
*Glassfish v4_b69*, while it runs on *Glassfish 3.2.1.1*, by raising the
following info message _"[failed to localize]
jersey.app.registered.classes(javax.ws.rs.core.Application,
[])|#]"_ which it should be *error* not *info* message also.
