JB, I'm not sure how you can help me here, except maybe to type in
some diagnostic suggestions -- or to tell me where there's a working
example of using the hibernate-validator feature that is included in
Karaf that I can crib from.
Let me explain how I got here. I needed to use bean validation.
The hibernate-validation feature in karaf enterprise seemed like what
I wanted, but I don't have the necessary maven repos to touch the
enterprise feature collection. So I made my own feature with the same
bundles, and included the code I sent along to avoid fussing with the
SPI.
Thus, my feature includes the bundle from glassfish that contains the
EL implementation with com.sun.el in it.
Meanwhile, all this goes into a Karaf assembly that also has pax-web.
As we have seen, pax-web also has
com/sun/el/ExpressionFactoryImpl.class. But it does not seem to export
it.
However, package:exports says:
karaf@root>package:exports | grep com.sun.el
com.sun.el | 2.2.4
| 174 | org.glassfish.web.javax.el
Note the lack of '-d'.
bundle:headers for the pax-web bundle does not show an export of com.sun.el.
Here's one more backtrace: bundle 65 does not import com.sun.el, so I
don't see how it can possibly find it.
All the code I have here works in a simpler pax-exam test which does
not involve a web service; but it's all the same bundles.
