-----------------------------------
Summary: CXF 3.0 implementation issue with JAX-RS
Key: CXF-5702
URL: https://issues.apache.org/jira/browse/CXF-5702
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.0.0-milestone2
Environment: Windows
Reporter: Kou, Zhi Qiang
Priority: Blocker
It seems CXF JAX-RS implementation has something wrong with the relationship
between defined servlet-mapping and the value of ApplicationPath annotation.
>From JSR-339 spec, section 2.3.2: If the Application subclass is annotated
>with @ApplicationPath, implementations are REQUIRED to use the value of this
>annotation appended with ”/*” to define a mapping for the added server.
>Otherwise, the application MUST be packaged with a web.xml that specifies a
>servlet mapping.
Also from ApplicationPath javadoc:
Identifies the application path that serves as the base URI for all resource
URIs provided by Path. May only be applied to a subclass of Application. When
published in a Servlet container, the value of the application path may be
overridden using a servlet-mapping element in the web.xml.
>From above information, if both servlet-mapping in web.xml and ApplicationPath
>has value, only one of them should be used as the base URI, and it should be
>the value of servlet-mapping in web.xml.
In my application, my web.xml looks like below. There are two servlet defined,
each for one jaxrs application. And the servlet-mapping values are defined as
"/first/*" and "/second/*".
<servlet>
<servlet-name>rest1</servlet-name>
<servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.ibm.sample.jaxrs.UserDemoApplication</param-value>
</init-param>
</servlet>
<servlet>
<servlet-name>rest2</servlet-name>
<servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.ibm.sample.jaxrs.GroupDemoApplication</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>rest1</servlet-name>
<url-pattern>/first/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>rest2</servlet-name>
<url-pattern>/second/*</url-pattern>
</servlet-mapping>
And in my application classes:
@ApplicationPath("userdemo")
public class UserDemoApplication extends javax.ws.rs.core.Application {
@ApplicationPath("groupdemo")
public class GroupDemoApplication extends javax.ws.rs.core.Application {
So in this case according to spec and javadoc, "/first/*" and "/second/*"
should be used as the base URI, but not the "userdemo" and "groupdemo".
But in the real case I can only access the resources via URLs:
http://localhost:9080/SingleParameterCxf/first/userdemo/users/eric
http://localhost:9080/SingleParameterCxf/second/groupdemo/groups/root
======
However if I implement the same application using Jersey RI libs, I can access
my resources via URLs:
http://localhost:9080/SingleParameterJersey/first/users/eric
http://localhost:9080/SingleParameterJersey/second/groups/root
My feeling is Jersey RI implementation is correct behavior according to SPEC
and JavaDoc. Please let me know if my understanding is correct or not.
Any help is highly appreciated! Thank you!
