@BeanParam and CDIExtension.webApplication NullPointerException

juvonen Apr 11, 2014 7:56 AM

Hi,

This might be tough one, but if anybody good even hint the direction it would be great...

So the issue happened while changing an EAR project to use @beanparam. Depending how many fields I annotate under the @beanparam with @queryparam or @pathparam that many times the request fails to nullpointer exception in com.sun.jersey.server.impl.cdi.CDIExtension, webApplication being null. So lets say I call:

@Produces({MediaType.APPLICATION_JSON})

@Path("{id}")

@GET

public Response searchWithId(@BeanParam Request req) {}

Request has three fields with @queryparam annotation. The server will return 3 times bad request exception before working correctly. If I take one @queryparam away, two exceptions will be returned before it starts working.

What is the component that eventually initializes the the CDIExtension's webapplication? Why does this happen after the count of @queryparams and @pathparams in the class?

Seems that disabling the CDI by removing the beans.xml (and removing corresponding injections) fixes the issue. Root cause still unknown... Any ideas?

Did you ever solve this? I am having the same problem but I need the beans.xml to find my Rest interface and to inject my PersistenceContext. David

Hi,
So do you deploy to WildFly 10.1.0.Final or any other version/server? Would you be able to provide simple reproducer application? com.sun.jersey.server.impl.cdi.CDIExtension looks quite suspicious to me. Do you bundle Jersey impl to your deployment?

Well there is a basic example using @BeanParam at javaee7-samples/jaxrs/beanparam at master · javaee-samples/javaee7-samples · GitHub (which works fine at WildFly), but if you want to inject Request than you need to use @Context I think.

Interestingly, if I remove my @Context injection

@Context private HttpServletRequest request;

and use

HttpServletRequest request = ResteasyProviderFactory.getContextData(HttpServletRequest.class);

it works fine. I do not directly include Jersey in any of my deployments, but I did create a Wildfly 10 Hadoop module that does include it.
Thanks for your comment on @Context, it lead me in the right direction.
