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.
