CXF DOSGI ZOOKEEPER

Question

Good morning,

I'm looking for help please.I'm only a beginner.

I am using cxf-dosgi from (DOSGi Apache Karaf Feature distribution)

I want to make transparent use of services between two remote machines. So I have a karaf container on each of these two machines.

---

I tested this example : to start with two containers karaf hosted on the same machine then I changed the configuration to test with two containers hosted on two different remote machines. And it works great !

So I want to do the same thing to export to export my web services. I am using Spring DM. So I do this on the server side :

<osgi:service id="osgi-service" ref="myservice" interface="org.apache.camel.Endpoint"> <osgi:service-properties> <entry key="name" value="service"/> <entry key="service.exported.interfaces" value="*"/> </osgi:service-properties> </osgi:service>

I did the installations like in the tutorial with cxf dosgi version 1.6 But I get this error:

16:25:53,256 | ERROR | pool-21-thread-3 | w.service.RemoteServiceAdminCore  193 | 184 - cxf-dosgi-ri-dsw-cxf - 1.6.0 | failed to create server for interface org.apache.camel.Endpoint

Have you an idea of what is wrong?

Answer 1

Ouch .. what are you doing with 1.4-SNAPSHOT. First it is not a release and second it is quite old.

Another thing that looks suspicious is the service.exported.interfaces=myInterface. It should be a fully qualified java interface name. For the start try service.exported.interfaces=* for it.

You should start with my CXF DOSGi tutorial . The code there should work out of the box. You can then add your changes in the config. So it is easier than to start completely new.
