JAXB module dependency

[adamw]

Hello,

I have a webapp which, through a third-pary library, uses JAXB in the following way:

JAXBContext.newInstance(typePackage, c.getClassLoader());

where c is a class from the library.

The exception I am getting from this line is:

javax.xml.bind.JAXBException: Provider com.sun.xml.internal.bind.v2.ContextFactory not found

- with linked exception:

[java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory from [Module "deployment.jbison-frontend-knob.yml:main" from Service Module Loader]]

as the platform-default provider is tried to loaded.

I wanted to expose JAXB to my app by adding a module dependency. To do that, I add a manifest file with the following contents:

Dependencies: javax.xml.bind.api

but this didn't change anything.

(I also tried adding a non-existent module, and got a deployment exception, so the manifest is picked up by the AS)

Do I need to add any other module dependency? Or just bundle a jaxb impl with the application?

Btw. this used to work in AS6.

I had similar issue with my webapp. I added jaxb-impl.jar and it worked. Try adding jaxb impl.

Thanks, I'll try that, though I'm wondering if this is the "correct" way to add jaxb to an app in AS7?

Try:

Dependencies: com.sun.xml.bind services

Works! Question is: why is it working now, what was wrong before and what's the "services" at the end, some kind of qualifier?

Thanks!

Replying to my own question, as the FAQ above says, "services" also imports the content of META-INF/services when declaring a dep on the module, making it visible to the JAXB lookup code.

The other difference was, earlier you were using the javax.xml.bind.api dependency and not com.sun.xml.bind. The javax one doesn't expose the sun JDK classes.
