JSF Beans cannot be resolved [PAXCDI-210] #255

Closed ops4j-issues closed 6 years ago

ops4j-issues commented 8 years ago

Former user created PAXCDI-210

If you setup Karaf 4.0.3 with OpenWebBeans and try to run the pax-cdi-sample4-jsf it deploys and runs without any error, but as soon as you hit the Vote Button of the poll.xhtml nothing happens, you should see "Your choice: whatever you have chossen" and in the console you should see the System.out.println (form submitted) from the submit method of the FrameworkBean, but neither of both happens, if you add a command button like:

<p:commandButton value="CLICK ME!" action="#{framework.submit}" ajax="false" />

inside the form and hit that button you'll get a javax.el.PropertyNotFoundException:

Could you please provide a completely reproductible test / instructions based on pax-cdi 1.0.0-SNAPHOT / pax-web-4.4.0-SNAPSHOT please ?

ops4j-issues commented 8 years ago

Marc Schlegel commented

Pax-Cdi-Extension has a uses-constraint on org.osgi.dto which is provided by R6 runtimes. Pax-Web 4.x still uses OSGi R5. You might want to check your backport from Pax-Web 6.0.0 to 4.4.x.

I've added a integration-tests in master for Jetty and Undertow to master but not all injections work as desired.

ops4j-issues commented 8 years ago

Guillaume Nodet commented

The dependency is that pax-cdi depends on pax-web, not the opposite, so I don't think this is a very big problem that pax-cdi depends on R6 while pax-web depends on R5.

Is it expected that SomeSessionBean is annotated with @javax.faces.bean.SessionScoped instead of @javax.enterprise.context.SessionScoped ?

ops4j-issues commented 8 years ago

Guillaume Nodet commented

I have some changes to make the various combinations of openwebbeans/weld/jetty/undertow work, but I don't think any of them has been integrated with JSF.

The pax-cdi-undertow-weld bundle has some support for JSF, but I haven't been able to make it work so far:

I haven't seen any way to augment the pax-web WebApp application so far, so I think I'll defer this issue.

I've pushed my changes to clean / fix pax-cdi / pax-web integration with
https://github.com/ops4j/org.ops4j.pax.cdi/commit/1f8604e11e773f25d254fc01c10ade409370a949

This doesn't provide CDI / JSF support though.

I've fixed the wrong annotation for SessionScoped in the sample. @javax.enterprise.context.SessionScoped should be used.

Any update on this issue? Do we need to do something on Pax-Web side?

ops4j-issues commented 6 years ago

Grzegorz Grzybek commented

On pax-web side, I added some important improvements, so pax-cdi + jsf works. There's even dedicated integration test. The change is here.

Summarizing the change, I ensured that the listeners declared in faces-config.xml fragments are NOT registered too early (during web app parsing), but rather by org.ops4j.pax.web.jsp.JasperInitializer.

There's canonical example created here.

And changes in pax-cdi itself are pending in this branch. I hope to have them merged soon.
