servlet transport question
Hi,
I want to add soap stack to my web application. I decided for CXF. This
page http://cwiki.apache.org/CXF20DOC/servlet-transport.html shows it
could be possible. I set up web.xml and now I want to bind the servlet
to bus, as specified in documentation:
// cxf is the instance of the CXFServlet
Bus bus = cxf.getBus();
BusFactory.setDefaultBus(bus);
Endpoint.publish("/Greeter", new GreeterImpl());
The question is: how can I get the CXFServlet instance? J2EE's
getServlet() method is deprecated.
1) I dont want to add spring to my project so I want to use programmatic
way.
2) My application is a web application running in jetty container, so
starting jetty within jetty is not good option.
3) Endpoint has no method publish, but EndpointImpl.
Thank you
Leos
PS1 documentation says that to build samples you need ant 1.6. I've got
CXFServlet, but it fails, that verbose attribute is not supported
PS2 javadoc from installer does not contain CXFServlet

Seems like it is already done inside startup of CXFNonSpringServlet
class... I think I saw in the sources, so the only thing you need to do is
run Endpoint.publish after CXFNonSpringServlet has been run. So, remember to
have an startupvalue for ur servlet greater than CXFNonSpringServlet to
avoid it being run before CXFs.
How have you solved it? Or is it set up behind the scene automatically in

My suggestion is your endpoint publishing code need be put into the
AbcCxfServlet, so you could get the full control of the bus.
BTW, CXFNoSpringServlet will replace Jetty http transport factory with
the servlet transport factory.
You need to call the
BusFactory.setDefaultBus(bus);
just before
Endpoint.publish(endpointUrl, new UserAccountServiceImpl());
If you call the publishing code in another servlet which could load by another classloader, CXF will create another bus for this endpoint.
The service url should be a related path, such as "/users". CXF don't
know the application's name, so it will update the endpoint's address
with the request url and the related path is the best way to resolve
this problem.

Basically, you can extends the CXFNonSpringServlet[1] and the setup
default Bus part before you call the endpoint.publish
And you also need to change the web.xml's <servlet-class> with your
extended servlet :)

Rafael,
thank you for your message. Especially the note about FQCN for Endpoint is crucial for me! Can somebody update http://cwiki.apache.org/CXF20DOC/servlet-transport.html ?

Please put snippet, how to configure the Bus (setup the servlet). The web.xml part is clear:
<servlet>
<servlet-name>CXFServlet</servlet-name>
<display-name>CXF Servlet</display-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
But how to manage this part?
// cxf is the instance of the CXFServlet
Bus bus = cxf.getBus();
BusFactory.setDefaultBus(bus);
How have you solved it? Or is it set up behind the scene automatically in 2.0.5 release?
Thank you

Hi Leos,
I managed to get CXF running on Tomcat without Spring... let me try do
describe what I had to do in order for it to work:
First of all I had problems using the cxf-incubator jar with every module
bundled, so, I got the modules separate from modules directory. I remember
that I read somewhere that if jetty libs were in classpath they might
present problems to run on tomcat so that's why I decided not to use the
bundled jar.
After, I configured CXFNonSpringServlet on my web.xml file and then I had
setup a Servlet (it could be a filter as well) with loadonstartup to
register the Services I had using: Endpoint.publish. Be careful not to
import the wrong Endpoint (right one is from: javax.xml.ws) class.
I am sending the list of jars I have on my web application but beaware that
it is mixed with hibernate, jpa, jsf and some seam libs... you might be able
to find out which ones you need by only importing the ones found on cxf

The publish method is on javax.xml.ws.Endpoint, not
org.apache.cxf.endpoint.Endpoint.

I looked at it but it does not seem to solve my situation. I still don't know how to fetch servlet instance, so I can set up Endpoint. Probably I will need sample .war to understand how to achieve this functionality. I miss the point. As I understand servlet API, it is not possible. If you have .war, you cannot start embedded jetty. So it makes sense that CXF will utilize CFX*Servlet as its transport. But that Bus binding complicates the thing, because it requires instance of the servlet. But you cannot get it from web application, can you?

This issue is not answeared. I guess that documentation is obsolete and I shall create new instance of org.apache.cxf.endpoint.EndpointImpl, is it correct?

Will you guys fix README or common_build.xml?

I mentioned an issue that javadoc in distribution zip is not complete.
I hope that my notes will help you.

There's a CXFNonSpringServlet that you can use that may be of help for
you, but IIRC it is not in heavy use and therefore not very well
documented:
