Re: [equinox-dev] OSGi and javax.jws.WebService with Java 11

Hi Lars,

obviously the implementations want to have different Jaxb implementations. com.sun.xml vs the glassfish one. Maybe choosing just the obe from the Jax-Ws stuff is your candidate.

This is why we use EMF for that ­čśë

Betreff: Re: [equinox-dev] OSGi and javax.jws.WebService with Java 11

Hi Mark,

thanks. The additional fragment was indeed necessary. I added it and
now it complains about the JaxB configuration.

Caused by: jakarta.xml.bind.JAXBException: return is not a valid
property on class
com.example.rcpclient.handlers.jaxws.SayHelloResponse at
org.glassfish.jaxb.runtime.v2.runtime.JAXBContextImpl.getElementPropertyAccessor(JAXBContextImpl.java:908)
at com.sun.xml.ws.db.glassfish.JAXBRIContextWrapper.getElementPropertyAccessor(JAXBRIContextWrapper.java:91)
at com.sun.xml.ws.server.sei.EndpointResponseMessageBuilder$DocLit.<init>(EndpointResponseMessageBuilder.java:228)
ÔÇŽ 54 more

I didn't know that Java Webservices uses JaxB under the hood. :-O

I will try to configure this and update this message thread with the results:

For reference, here is an example with the current state:

Thanks also to Gunnar for the tip and Christoph for the amazing m2E /
PDE integration which makes using libraries super easy.

Best regards, Lars
