[jboss-jira] [JBoss JIRA] (WFLY-13076) Opentracing fails to load on EAR deployment

[Roy Golan (Jira)]

    [ https://issues.redhat.com/browse/WFLY-13076?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13968817#comment-13968817 ] 

Roy Golan commented on WFLY-13076:
----------------------------------

OK I took a simple war we do have under the ear, and added a simple JAXRS resource there, invoked it, and started getting spans, without any configuration.
So this means our restapi.jar needs something to be added to its deployment. What should it be then?

> wildfly 18, an EAR application (ovirt-engine ), I'm trying to enable opentracing, and failing.
> I added this to our xml:
> ```
> <extension module="org.wildfly.extension.microprofile.opentracing-smallrye"/>
> ...
> <subsystem xmlns="urn:wildfly:microprofile-opentracing-smallrye:1.0"/>
> ```
> Exported Jaeger environment vars:
> ```
> export JAEGER_SERVICE_NAME=ovirt-engine
> export JAEGER_REPORTER_LOG_SPANS=true 
> export JAEGER_SAMPLER_TYPE=const
> export JAEGER_SAMPLER_PARAM=1 
> ```
> And debugged the `TracerProducer` which throws:
> ```
> "Method threw 'org.jboss.weld.exceptions.IllegalStateException' exception. Cannot evaluate org.jboss.weldx.servlet.ServletContext$$Proxy$_$$_WeldClientProxy.toString()" 
> ```
> The deployment structure is:
> | engine.ear
>     - bll.jar                  EJB and CDI beans
>     - lib/vdsbroker    CDI
> | restapi.war            JAXRS , also CDI beans
> | Jboss-Modules
>     common.jar
>     utils.jar
>     dal.jar                    CDI 
>
