    salvuzzo Novice

      Hello, i have a problem.I created a project with SwitchYard, with a Service and ServiceBean. When deployed this project, i get this error:

       

      22:08:45,822 INFO  [org.switchyard.component.sca] (MSC service thread 1-4) SWITCHYARD039200: Unable to resolve cache-container cluster.  clustering for <binding.sca> will not be available for services and references.

          Hello,

          This looks to be a strange one.  The container looks like it deployed the application, but the console doesn't know about it.
          Is this maybe a Wildfly Camel installation?  That installation might not have all the SwitchYard parts.  Else, please tell us about which EAP/Wildfly you are running, and how SwitchYard was installed.

          Regards,

          Rick

            Hello Rick,

            Thanks for you answer. I have downloaded l'application server wildfly 8.1, then i have downloaded switchyard-2.0.0.Final-WildFly. I unpacked the archive switchyard into wildfly 8.1 replacing files. something wrong? I then tried to install switchyard using the build.xml present within wildfly 8.1

              Hello,

              Ah, this may be the reason for the message.

              The first comment on [1] indicates that there was some question about use of Wildfly 8.1 with SwitchYard 2.0.  (Some users thought it would be ok, but the documentation tells us 'SwitchYard 2.0.0.Final has been tested against Wildfly 8.0.0.Final ').   So we may have a subtle bug when running against Wildfly 8.1.

              Is it necessary that you use Wildfly 8.1?  If not, you might consider trying against the tested version (Wildfly 8.0) or better yet use EAP 6.4.  Is that a possibility for you?

              Rick

               

              [1] SwitchYard 2.0.0.Final now available

                Hello,

                I read that even the version wildfly 8.1 supports SwitchYard 2.0. Anyway for to make a test, i have installed wildfly 8.0 but also in wildfly 8.0 i get this error:

                  Salvuzzo,

                   

                  There's two things here - the cache-container warning, and the xerces errors.

                   

                  cache-container : this is just an info message, there may be something that needs to be set in the wildfly configuration we're shipping.     I've logged a JIRA here (https://issues.jboss.org/browse/SWITCHYARD-2874) - we'll investigate, but unless you were planning on using SwitchYard + WildFly clustering right away, I think we're okay for now.     Keep an eye on updates to that JIRA.

                   

                  xerces errors : I think the problem is basically the same as here :

                   

                  https://issues.apache.org/jira/browse/RAT-158

                   

                  and that you're using a newer JDK that's setting properties that Xerces doesn't really know about.   I did a mvn:dependency:tree using your pom.xml and I don't see xerces in the list, so I think it's being pulled in by Maven.    I don't think it's harmful though.
