Virgo with CXF Web Services [message #661694]

Hi,

Sorry if this is already answered somewhere, but I've been searching for a while and haven't been able to find any information about this.

Are there any tutorials available or any information about writing CXF web services as osgi bundles for Virgo? I've tried following the instruction in the greenpages sample app, but instead of creating a web app I've created a project that has a CXF service, but I'm obviously doing something completely wrong since I just can't get the application to start.

I can provide more information on the problem I'm having, but if there's already any tutorials available about this I'm happy to check them out first.

Cheers,
Adam

I'm not aware of any tutorials so, unless others who have used CXF with Virgo chime in, you'd better describe the symptoms.

Hi,

I hope it is not too late for my answer.
Here is how you can run one very simple web application that uses CXF WS.

download CXF - http://cxf.apache.org/download.html
download Axiom - http://ws.apache.org/axiom/download.cgi

Some of the CXF jar files have OSGi metadata in their MANIFEST.MF file so you can use them directly from the CXF distro, but some of them do not have so here is what I've done:

From CXF distro you can use:
- cxf-2.3.3.jar
- geronimo-jaxws_2.2_spec-1.0.jar
- geronimo-ws-metadata_2.0_spec-1.1.3.jar
- neethi-2.0.4.jar
- XmlSchema-1.4.7.jar

From the EBR you can download:
- com.springsource.javax.wsdl-1.6.1.jar
- com.springsource.javax.xml.bind-2.2.0.jar
- com.springsource.nu.xom-1.1.0.jar
- com.springsource.org.apache.xml.resolver-1.2.0.jar
- com.springsource.org.jaxen-1.1.1.jar
- com.springsource.org.objectweb.asm-3.2.0.jar

The axiom.jar does not have OSGi metadata in the MANIFEST.MF, so I used bundlor in order to create such.

So put all 12 bundles in the <Virgo-Home-Dir>/repository/usr.
Open <Virgo-Home-Dir>/lib/java6-server.profile
There is org.osgi.framework.system.packages property
Add one more package: javax.xml.namespace;version="1.0.0"

org.osgi.framework.system.packages = \
...
 javax.xml.namespace,\
 javax.xml.namespace;version="1.0.0",\
...

Start Virgo
Then put in the pickup directory the attached web app bundle.
Request http://localhost:8080/cxf/ws/AccountProcess?wsdl

Hope this helps.
Regards
Violeta

Thanks a lot, it's definitely not too late and that's exactly what I'm looking for.

Unfortunately I'm just looking into this when I have a few minutes to spare, which is why I haven't replied up until now.

Cheers,
Adam

With CXF 2.4.0, if you use Karaf, it should be a LOT easier. CXF 2.4.0 has a Karaf features file that will allow Karaf to pull in all the required 3rd party bundles and get them all started.

Another option would be to look at Talend's Service Factory:
http://www.talend.com/download.php?src=HomeP age#SF

The main download has the OSGi container all pre-setup with all the dependencies and everything. That could help you figure out what you need.

The "examples" download has a bunch of examples that show how to build CXF services and deploy them into OSGi.

Hi,

I'm trying to get the example provided by Violeta to work. I'm using the exact versions specified in her post (CXF 3.3.2, etc.). I get the following when I start up Virgo.

I am using Virgo Tomcat Server 3.6.1.RELEASE. Any help would be appreciated.

Paul,

Did you include those other bundles i.e neethi and the geronimo one to your repository? Possibly the axciom one as well. Looks like you are missing dependencies.

Are you using a plan to run them? If so you need to include them before your cxf bundle to ensure they start up before the one that depends on them.

Neil,

I was missing some of the bundles that I downloaded from the EBR. I started moving them into the repository, stepped away from my computer and then forgot to move the rest. It now works. Thank you for your help.

Paul
