Re: pax-web not recognizing JAXB implementation with Java 11

[Achim Nierbeck]

Hi,

how are you using Pax Web and which version?

As far as I know Java 11 runs smoothly with the setup the Apache Karaf project has been using.

I was under the impression, we already had some adjustments in the pax web project for Java 11.

regards, Achim

Hi all!

I'm trying to migrate our OSGi application to Java 11. However I cannot get pax-web to find the JAXB implementation. Which leads to a exception like the one below when it tries to parse a web.xml. I've added `com.sun.*` to bootdelegation but oddly enough that doesn't seem to matter.

I'm using the Apache Servicemix jaxb implementation bundle (org.apache.servicemix.bundles.jaxb-runtime) together with the Jakarta API bundle (jakarta.xml.bind-api). I've also tried adding a fragment which makes the jakarta API bundle import the apache servicemix jaxb implementation package (com.sun etc.). That also didn't work.

Can someone tell me what the proper way is to make pax-web recognize the JAXB implementation?

Regards,

Jasper

Are you using pax-web in Karaf? If so, which version?
