cxf advanced examples
Hi,
this is a humble request for input on how to implement cxf
interceptor/filters in cxf (ws/rs) and tomee.
At cxf home the docs usually shows spring beans implementation but I "old
school" and like to do it the ee6 way ;-)
Does anyone know any resources?
Maybe something for tomee examples also?
I would very much like to contribute, but right now I'm stuck with http
filters....

1. yes in tomee but not always portable
2. also possible through cxf annotations
3. can be with annotation only too
but globally yes

That means, in TomEE perspective, sometime this autumn?
I agree, better to wait for cxf 3 in tomee.
So, Im I right defining it like this:
1. Providers is OK in Application
2. interceptors i resources.xml/tomee.xml and openejb-jar.xml config
3. filters: web.xml(?)

Hi
it is not but we could support it but i'm almost -1 since jaxrs2 will
give portable hooks

Hwaastad, just interested to know where you are? I used to live in
Switerland and going snowboarding in the swiss and french alps. Your pic
looks like that. Am i close?

You can still write
http://svn.apache.org/repos/asf/tomee/tomee/trunk/examples/server-events/src/main/java/org/superbiz/event/AutoDiscoveredListener.java
and modify AppInfo to add the interceptors. Globally adding in the
ejbJarInfo of your app a new pojoConfigurations which is just what is in
xml.

I'm going to stay faithful to TomEE.
Don'nt need no portability :-)
@Anthony: my investigations are also because I'm not to keen on xml
programming.
On the other hand, I get Romains angle.

Thanks but that would waste time that can be valuably spent on other more
deserving things.

Yes, but that's why it is often in files and not in code.
If you really need it we can add it but it was just to explain why it was
like it today.

I know you're right and usually at some point we have to configure something
that is specific to an implementation.

Re: cxf advanced examples

basically this is not portable. You can also observes tomee internal events
and modify OpenEjbJar (openejb-jar.xml mapping) to add it programmatically.

I was hoping there was more to it than that. Like being able to inject
interceptors and do away with config in resources.xml and openejb-jar.xml.

Hmm, it is already in TomEE and better than it can be in CXF since it
supports EJBs (think to it and trnsactional endpoints, that's just
awesome)

Hi,
thanks alot. I guess knowing the service and openejb-jar configuration is
important.
I wonder, cxf providers can also be configured in openejb-jar. But it can
also be added to Application (ApplicationPath).
Do you know if something similar is possible for filters/intercaptors?

Re: cxf advanced examples
Posted by Anthony Fryer <ap...@hotmail.com>.
I have a simple cxf interceptor in a project that just forces the text of an
xml element in a web service response to be wrapped in a CDATA element. It
would probably make for a good example.
There's 2 classes I have to implement the interceptor...
public class CDataContentWriter extends DelegatingXMLStreamWriter {
private static final Pattern XML_CHARS = Pattern.compile("[&<>]");
private String currentElementLocalName;
public CDataContentWriter(XMLStreamWriter writer) {
super(writer);
}
@Override
public void writeCharacters(String text) throws XMLStreamException {
boolean useCData = XML_CHARS.matcher(text).find();
if (useCData) {
super.writeCData(text);
} else {
super.writeCharacters(text);
}
}
@Override
public void writeStartElement(String prefix, String local, String uri)
throws XMLStreamException {
currentElementLocalName = local;
super.writeStartElement(prefix, local, uri);
}
}
public class CDataWriterInterceptor extends
AbstractPhaseInterceptor<Message> {
public CDataWriterInterceptor() {
super(Phase.PRE_STREAM);
addAfter(AttachmentOutInterceptor.class.getName());
}
@Override
public void handleMessage(Message message) throws Fault {
message.put("disable.outputstream.optimization", Boolean.TRUE);
XMLStreamWriter writer =
StaxUtils.createXMLStreamWriter(message.getContent(OutputStream.class));
message.setContent(XMLStreamWriter.class, new CDataContentWriter(writer));
}
}
Then in my resources.xml (or you could use tomee.xml) i declare the
interceptor as a service...
<resources>
....
<Service id="cdataWriterInterceptor"
class-name="au.com.cyberavenue.cxf.CDataWriterInterceptor"/>
</resources>
Lastly, I had to create an openejb-jar.xml (located in my WEB-INF folder)
which is where i hook up the interceptor service to individual web
services...
<openejb-jar xmlns="http://www.openejb.org/openejb-jar/1.1">
<ejb-deployment ejb-name="GetBoardingPassDataImpl">
<properties>
cxf.jaxws.out-interceptors = cdataWriterInterceptor
</properties>
</ejb-deployment>
<ejb-deployment ejb-name="BoardingPassBarCodeImpl">
<properties>
cxf.jaxws.out-interceptors = cdataWriterInterceptor
</properties>
</ejb-deployment>
</openejb-jar>
So I ended up with 2 webservices where the response xml will have CDATA
elements instead of escaped strings. Hope this helps.
Regards,
Anthony
