Hi,
I have a couple of OSGi services which are available as remote OSGi service
with CXF-DOSGi. The services are registered with the following props, and that
all works fine:
Dictionary<String, Object> props = new Hashtable<String, Object>();
props.put("name", "MyServiceImpl");
props.put("type", "internal");
props.put("service.exported.interfaces", "*");
props.put("service.exported.configs", "org.apache.cxf.ws");
props.put("org.apache.cxf.ws.address", "http://"; + serviceHost + ":" +
servicePort + "/MyService");
props.put("org.apache.cxf.ws.httpservice.context", "/MyService");
However, I would like to use the port defined with org.osgi.service.http.port
property as the service port. That doesn’t work though because CXF creates a
new instance of JettyHttpDestination for every used port. This is from
JettyHttpDesitination.java where servers for ea. port are created:
protected void retrieveEngine()
throws GeneralSecurityException,
IOException {
if (serverEngineFactory == null) {
return;
}
engine =
serverEngineFactory.retrieveJettyHTTPServerEngine(nurl.getPort());
if (engine == null) {
engine = serverEngineFactory.
createJettyHTTPServerEngine(nurl.getHost(), nurl.getPort(),
nurl.getProtocol());
}
And port 8088 is already claimed by the HttpService registered by CXF:
g! services (objectClass=*HttpService)
{org.osgi.service.http.HttpService,
org.eclipse.equinox.http.servlet.ExtendedHttpService}={service.description=Equinox
Jetty-based Http Service, service.vendor=Eclipse.org<http://Eclipse.org>,
http.port=8088, service.id=64, service.bundleid=31, service.scope=bundle}
"Registered by bundle:"
org.eclipse.equinox.http.servlet_1.1.400.v20130418-1354 [31]
"Bundles using service"
org.apache.cxf.cxf-rt-transports-http_3.1.6 [82]
cxf-dosgi-ri-dsw-cxf_1.7.0 [138]
The CXF-DOSGi
documentation<http://cxf.apache.org/distributed-osgi-reference.html> says about
the org.apache.cxf.ws.httpservice.contex:
"When this property is specified, the OSGi HTTP Service is used to expose the
service, rather than a dedicated Jetty HTTP Server. This property doesn't allow
the specification of a port number, as this is provided by the HTTP Service.
The Distributed OSGi distributions come with Pax-Web, for which configuration
information can be found at http://wiki.ops4j.org/display/paxweb/Configuration,
however other OSGi HTTP Service implementations are potentially configured
differently.”
When I try that, the service is bound to localhost:9000 instead of
0.0.0.0:8088, which seems to happen in
org.apache.cxf.dosgi.dsw.handlers.PojoConfiguration.java:
private String getPojoAddress(Map<String, Object> sd, Class<?> iClass) {
String address = getClientAddress(sd);
if (address != null) {
return address;
}
// If the property is not of type string this will cause an
ClassCastException which
// will be propagated to the ExportRegistration exception property.
Object port = sd.get(Constants.WS_PORT_PROPERTY);
if (port == null) {
port = "9000";
}
address = "http://localhost:"; + port + "/" +
iClass.getName().replace('.', '/');
LOG.info("Using a default address: " + address);
return address;
}
I am trying to understand what I am missing for a while now, and every now and
again on a quiet Fri. afternoon (…) I take another stab at it, but I am not
getting much further.
FWIW… the CXF servlet IS registered under the port defined by
org.osgi.service.http.port.
This is all based on
CXF: 3.1.6 and CXF-DOSGi: 1.7.0
Java 8
Eclipse Equinox 3.10.2
I checked the release notes for 1.8.0 but didn’t see anything related to this
issue.
Any suggestions or pointers in the right directions would be greatly
appreciated.
Thanks,
Erwin
