Hi Jarek,
I'm so sorry to call you Jacek last night.
I should be more careful next time! First two characters match, last
three not...
I have a work around for that. And if it's up to me - I'm happy
because my application deploys and runs :)
But it does not look good.
G2.1 with Tomcat uses Axis2 as JAX-WS provider.
When I expose some of my SLSBs methods as web services G2.1 adds Axis2
classes to the class loader (for example the Axis2 ServiceClient
class).
I'm not defining dependency for axis2-kernel (this package contains
ServiceClient class) explicitly because there will be class cast
exception during deployment.
Then I simply add:
<non-overridable-classes>
<filter>org.apache.axiom.</filter>
</non-overridable-classes>
to my descriptors.
And it works. But it is a little bit tricky.
thanks and best regards!
Łukasz
