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

after changing the JAXB implementation (thanks Mark) I rab into the next issue, It looks to me that the jax-ws implementation is not ready to run in Equinox, see https://github.com/eclipse-ee4j/metro-jax-ws/issues/128 for details.

I was able to start a webservice by modifying the classloader see https://github.com/vogellacompany/eclipsercp-javaws-java11/blob/main/com.example.rcpclient/src/com/example/rcpclient/parts/SamplePart.java
This enables the client to start webservices in his RCP app (which are used to communicate to an AS/400 backend). Once #128 is resolved or a better solution is found we hope to update this "hack".

You find a demo for this approach in https://github.com/vogellacompany/eclipsercp-javaws-java11

Thanks again everyone for your help, Lars

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 😉

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)
… 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:

https://github.com/vogellacompany/eclipsercp-javaws-java11

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

Best regards, Lars
