I have a problem with a 'slightly' more complex type than based Java types in
my exposed web service that doesn't seem to work.
Here's the setup:
I have a simple server that has as a return type a 'custom' type that wraps a
string for this example.
The server bundles deploy fine, and the web service works great from the
Eclipse Web Services Explorer.
When I try to bring up the Client in different instance of felix things start
falling apart. If I don't use a custom type... use String for instance
everything works fine.
However, when I use my custom type I get this error on the actual call to the
server, not at Binding/Wiring time.
Dec 14, 2009 10:01:34 AM org.apache.cxf.phase.PhaseInterceptorChain doIntercept
INFO: Interceptor has thrown exception, unwinding now
org.apache.cxf.interceptor.Fault: Couldn't instantiate class.
example.wstype.WsType. Nested exception is java.lang.InstantiationException:
example.wstype.WsType
at
org.apache.cxf.aegis.databinding.XMLStreamDataReader.read(XMLStreamDataReader.java:63)...
So, I figured I'd cheat and placed the package that contains the type into the
felix org.osgi.framework.system.packages.extra property. I get the same error.
The following is the source if anyone else wants to give it a try. Yes, I'm
using iPOJO.
Oh yeah, here's the an important line from the example.wsserver bundle:
Export-Package: example.wsserver.*, example.wstype.*
I can't imagine that I'm the first person to deal with this, so my assumption
is that I'm doing something wrong. Based on my reading, I may have to add some
mapping info to the AegisContext... but I can't figure out how to do that in an
OSGi/Felix way.
Any help would be greatly appreciated. I would maybe suggest expanding the
iPOJO w/ DOSGi example here
(http://felix.apache.org/site/apache-felix-ipojo-dosgi.html) to include a
complex type as an in/out parameter.
