REST app with CXF 2.4 gives Can't find request for observer error.

[odyssey045]

Hi,

I saw many users complain about a similar error with WSDL based CXF apps but
none for REST based apps and hence this question..
I am trying to get started with a simple REST based CXF and spring app. I
followed a demo and created a simple service called "categoryService" which
lists some categories and books in each category.

My beans.xml looks something like this:'


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/jaxrs"
xmlns:cxf="http://cxf.apache.org/core"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxrs:server id="categoryService" address="/">
<jaxrs:features>
<cxf:logging/>
</jaxrs:features>
<jaxrs:serviceBeans>
<ref bean="categoryServiceBean" />
</jaxrs:serviceBeans>
</jaxrs:server>
<bean id="categoryServiceBean"
class="com.demo.cxf.server.CategoryService"/>
</beans>

And my jaxrs.xml used by spring looks something like tis:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<bean id="categoryService" class="com.demo.cxf.server.CategoryService">
<property name="categoryDAO">
<ref bean="categoryDAO"/>
</property>
</bean>

<bean id="categoryDAO" class="com.demo.cxf.dao.CategoryDao"></bean>
</beans>


Finally my web.xml looks something like this:

<?xml version="1.0" encoding="ISO-8859-1"?>
&lt;!DOCTYPE web-app

Is there something that i am missing over here besides the configuration
files?? When i deploy my war into tomcat 7, i get the following message:

But when i try to access, something like

Tomcat just says back to me

Hi,

That happens for REST apps as well...

jaxrs:server/@address is "/" so an initial match should've been
successful (not sure if your root resource actually starts with /jaxws
- but that is the next stage). It appears the endpoint has not been
created at all ...

Can you get some more info from the logs ? Perhaps CategoryService is
not a valid root resource...

Cheers Sergey

The /jaxws happens to be the context root of the application.

Not sure if this helps, but my simple java code goes something like this..

@Path("/categoryservice")
@Produces("application/xml")
public class CategoryService {

CategoryDao categoryDAO = null;
public CategoryDao getCategoryDAO() {
return categoryDAO;
}
//injected with spring
public void setCategoryDAO(CategoryDao categoryDAO) {
this.categoryDAO = categoryDAO;
}


@GET
@Path("/category/{id}")
@Consumes("application/xml")
public Category getCategory(@PathParam("id") String id) {
System.out.println("The id to fetch is "+id);
Category cat = (Category)getCategoryDAO().getCategory(id);
return cat;
}

You should see something like:

Try also check the services list from the browser:

Thanks! There was a typo in the book that was carried on without knowing the
significance of the error.. I am able to get a handle to the request now.. I
do have another error, which i will post in a separate post.

Hello,

I have quite basic questions about JAX-RS support in CXF (2.3.3) :

- If you look at servlet code and web.xml descriptor bellow, is it the good way to expose a REST ws (without using spring)
- How to remove "sf.setAddress("http://localhost:8080/")" ? => I don't know what will be the port number of the app server where my webapp will be deployed
- How to remove useless <init-param> for serviceClasses without runtime exception

Thanks and regards,
Anthony



Servlet code:

public class MyServlet extends CXFNonSpringJaxrsServlet {

public MyServlet() {
JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
sf.setTransportId("http://cxf.apache.org/transports/http");
sf.setResourceClasses(MyResource.class);
sf.setResourceProvider(MyResource.class, new SingletonResourceProvider(new MyResource()));
sf.setAddress("http://localhost:8080/");
sf.create();
}

Hello,
- If you look at servlet code and web.xml descriptor bellow, is it the good way to expose a REST ws (without using spring)

The code which is currently in MyServlet is usually used only when
creating standalone JAX-RS endpoints, backed up by embedded Jetty - in
such cases absolute URIs have to specified.
I'd recommend using CXFNonSpringJaxrsServlet directly, unless you need
to customize the way CXFNonSpringJaxrsServlet handles its init().

Post by Muller, Anthony
- How to remove "sf.setAddress("http://localhost:8080/")" ? => I don't know what will be the port number of the app server where my webapp will be deployed

I think you do not need that code at all

Post by Muller, Anthony
- How to remove useless <init-param> for serviceClasses without runtime exception

At the moment MyServlet does not really override
CXFNonSpringJaxrsServlet but rather proceeds with creating endpoints
on its own, thus a possible conflict, given that
CXFNonSpringJaxrsServlet does expect this parameter.
Consider removing MyServlet.

Hope it helps
Sergey

Thanks! There was a typo in the book that was carried on without knowing the

do have another error, which i will post in a separate post.
