I applied a patch submitted to the DOSGI JIRA project,
so this should be fixed on the trunk

Hi,
As far as I can tell, Aries doesn't use AOP or CGLIB to proxy the
service. Instead they use an interceptor mechanism: a Java class that
contains methods to define the behaviour to be executed before and after
the service invocation is done.
Kr,
Frederik.

Hello,
I have installed the latest single bundle release of CXF DOSGI in
Apache Aries 0.3. I have played around a bit with it and it works ok
to remotely expose a service (see blueprint definition below).
However, when I add a transaction attribute on the bean definition (in
comment below), the service is not exposed anymore. The purpose is not
to do transaction propagation from client to service but just to start
a transaction when the service method is invoked.
<service interface="dexia.osgipoc.sedm3.service.BankService"
ref="bankServiceBean">
<service-properties>
<entry key="service.exported.interfaces" value="*" /> <entry
key="service.exported.configs" value="org.apache.cxf.ws" /> <entry
key="org.apache.cxf.ws.address"
value="http://localhost:9090/bankservice"; /> </service-properties>
</service> <bean id="bankServiceBean"
class="dexia.osgipoc.sedm3.service.BankServiceImpl"
activation="lazy">
<!-- tx:transaction method="*" value="Required" /--> <property
name="actorService" ref="actorServiceRef" /> <property
name="accountService" ref="accountServiceRef" /> </bean> In the
console log I see (NULL for EndpointDescription):

It is most likely a bug to do with DOSGi CXF not able to get to the
actual interface class given that Aries must be proxifying it..
CXF has utilities to deal with such cases but I'm wondering, how the
proxification is done in this case, if Spring AOP or CGLIB is used then
a fix may be applied, can you create a simple test case somehow ?
As a workaround, please try experimenting with forcing CGLIB be used
Cheers, Sergey
While in the case that it works correctly, I see:

Thx a lot for the support,
