Hi András
I'm afraid I don't know the answer at the moment.
I agree that if an interface method declares a custom Exception then it
has to be thrown - I'm not seeing the attachment - do you see in the
debugger if ServiceInvocationHandler manages to match a Throwable
instance to one of the exception classes in the map, before proceeding
with throwing ServiceException ?
Cheers, Sergey

Hello Sergey,
thanks for the tips!
I tried the Greeter sample as well, and in my environment its exception
handling fails the same way I described before (the custom exception is
declared, no compilation error, but then a runtime exception / error
(execution stops :( )).
I debugged this exception as well at the client side (for me it only
shows that my custom exception is wrapped). I attached the variables
scrrenshot anyway, and I've also attached the debugged variables at
ServiceInvocationHandler's catch clause (exception_debugged_sih.png).
Are these proper?
Thanks,
András

Hi
Here is the way it's handled on the client side:
http://svn.apache.org/repos/__asf/cxf/dosgi/trunk/dsw/cxf-__dsw/src/main/java/org/apache/__cxf/dosgi/dsw/handlers/__ServiceInvocationHandler.java
<http://svn.apache.org/repos/asf/cxf/dosgi/trunk/dsw/cxf-dsw/src/main/java/org/apache/cxf/dosgi/dsw/handlers/ServiceInvocationHandler.java>
I don't recall if I was the last one who changed that code or if
David was applying more changes afterwards. I suspect that was code
was supposed to be compliant with the spec we were implementing at a
time :-)
Looking at this code:
http://svn.apache.org/repos/__asf/cxf/dosgi/trunk/samples/__greeter/client/src/main/java/__org/apache/cxf/dosgi/samples/__greeter/client/Activator.java
<http://svn.apache.org/repos/asf/cxf/dosgi/trunk/samples/greeter/client/src/main/java/org/apache/cxf/dosgi/samples/greeter/client/Activator.java>
suggests that custom exceptions have to be thrown - so I suspect
that if you get a ServiceException then no mapping was successful...
The best way to figure out what is happening is to checkout the
source, start the client container in a debug mode and get a
breakpoint in ServiceInvocationHandler...
Hope that helps a bit,
Cheers, Sergey

So I have some kind of misunderstanding about DOSGi CXF's exception
handling.
My scenario is the following:
I created a simple client-server architecture, where both client
and server
components run on Equinox and the communication is based on
DOSGi CXF. The
webservices worked fine, then I decided to put some
exception-handling into
the application. I subclassed java.lang.Exception to create a common
exception for my app, then subclassed that exception for specific
exceptions. Of course both client and server bundles use these
exceptions,
as I put them into the interface bundle.
Then I wanted to test the exceptions: the client called the
server side
service operation, which threw my specific exception, but it was
wrapped in
the following exceptions:
java.lang.reflect.__UndeclaredThrowableException /
java.lang.reflect.__InvocationTargetException /
org.osgi.framework.__ServiceException /
java.lang.reflect.__InvocationTargetException / MySpecificException
And here comes my question: Is this wrapping provided by the CXF
DOSGi
runtime? I mean is this the way it should work? If so, how could
I catch
this exception nicely on the client side? In nicely I mean that
so far the
only way I figured out was having a catch block for
UndeclaredThrowable (or
Exception.. :)), which just makes having custom exceptions
useless :) And
naturally, my IDE (Eclipse) wants the custom exception to be
catched..
I tried to make my application exception by subclassing
InvocationTargetException, but didnt work the way I wanted.
So I am a bit confused, I hope someone can clarify my issue.
Thanks in advance,
András Liter

Dear CXF Users,
I wonder if there is a separate mailing list for the
CXF-DOSGI subproject,
or can I write my question regarding CXF-DOSGI here?
Thank you,
András Liter
