    EJB and OSGI with JBoss App-Server 7.1.1.Final

      Hi,

      I have downloaded the actual JBoss Application Server 7 (jboss-as-7.1.1.Final) and I plan a Software-Architecture to use OSGI-Services from EJB-Stateless-Session-Bean. At this reason I implement a small prototype, a simple EJB-Echo-Bean to call a OSGI-Service.

      To inject the BundleContext in the Stateless-EJB I use the @Resource-Annotation

      1. Mr. Diesler describe this solution in https://docs.jboss.org/author/display/JBOSGI/Application+Server+Integration to inject the BundleContext.

       

      Here is the my simple EJB

      @Stateless

      public class EchoService implements EchoServiceLocal, EchoServiceRemote {

          @Resource

          BundleContext context;

          EchoIF service;

      :

          @PostConstruct

          public void init() {

            :

          }

         @Override

         public String echo(String str) {

            if(service != null) {

                return "OSGI: " + service.echo(str);

            } else if(context != null) {

                return "context: " + str;

            } else {

                return str;

              }

         }

      }

       

      But, the App-Container cannot deploy my EAR with the EchoService, because they throws a Exception like this:

      :

      Caused by: java.lang.IllegalArgumentException: Can not set org.osgi.framework.BundleContext field de.echo.EchoSe

      rvice.context to org.jboss.osgi.framework.internal.SystemBundleContext

      at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146

      ) [rt.jar:1.6.0_25]

      at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:150

      ) [rt.jar:1.6.0_25]

      at sun.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorImpl.java:63) [rt.jar:1.6.0_25

      ]

      at java.lang.reflect.Field.set(Field.java:657) [rt.jar:1.6.0_25]

      at org.jboss.as.ee.component.ManagedReferenceFieldInjectionInterceptorFactory$ManagedReferenceFieldInjec

       

      I found many other people with the same problem.

      I've tested a few solutions that are described here:

      https://community.jboss.org/thread/172622?start=15&tstart=0

      http://web.archiveorange.com/archive/v/wr91MTZQ817J3WkPms5p

      But none of these Solutions works.

      Have anybody a idea?

      Need the App-Container a special Module or a special configuration to inject the Bundle-Context in EJB´s?

      https://docs.jboss.org/author/display/AS7/OSGi+Subsystem+Configuration

       

      thanks,

        Jerry

          Have a look at from our latest jbosgi-1.1.0 distribution.

           

          [tdiesler@tdvaio example]$ mvn -Dtarget.container=jboss710 -Dtest=JavaEEIntegrationTestCase install

           

          The code is here: https://github.com/jbosgi/jbosgi/tree/1.1.0/testsuite/example/src/test/java/org/jboss/test/osgi/example/jbossas

           

          For the EJB3 deployment to see the OSGi APIs you need to have a few dependencies defined in your manifest

           

          final JavaArchive archive = ShrinkWrap.create(JavaArchive.class, EJB3_DEPLOYMENT_NAME);
          archive.addClasses(SimpleStatelessSessionBean.class);
          archive.setManifest(new Asset() {
              @Override
              public InputStream openStream() {
                  ManifestBuilder builder = ManifestBuilder.newInstance();
                  String osgidep = "org.osgi.core,org.jboss.osgi.framework";
                  String apidep = ",deployment." + API_DEPLOYMENT_NAME + ":0.0.0";
                  builder.addManifestHeader("Dependencies", osgidep + apidep);
                  return builder.openStream();
              }
          });

            Hi Thomas,

             

            this little line (Dependencies: org.osgi.core,org.jboss.osgi.framework) in the MANIFEST.ME-File

             

            is the point of success without a Exception!

             

            The Bundle-Context is injected!

             

            Thanks Thomas

              Hi Thomas,

               

              What are the Maven dependencies for the ManifestBuilder/JavaArchive classes ?

              I tried to add the org.jboss.osgi.spi and didn´t work

              Thank you.

                You can start from the examples that we provide.

                  Thomas,

                   

                  Thanks for the reply

                   

                  It´s possible to make a servlet access an OSGi service ?

                  I try to add the following code to my servlet init method::

                   

                  final JavaArchive archive = ShrinkWrap.create(JavaArchive.class, EJB3_DEPLOYMENT_NAME);
                  archive.addClasses(SimpleStatelessSessionBean.class);
                  archive.setManifest(new Asset() {
                      @Override
                      public InputStream openStream() {
                          ManifestBuilder builder = ManifestBuilder.newInstance();
                          String osgidep = "org.osgi.core,org.jboss.osgi.framework";
                          String apidep = ",deployment." + API_DEPLOYMENT_NAME + ":0.0.0";
                          builder.addManifestHeader("Dependencies", osgidep + apidep);
                          return builder.openStream();
                      }
                  });
                  

                   

                  But i kepp getting this exception: 

                  Caused by: java.lang.IllegalArgumentException: Can not set org.osgi.framework.BundleContext field de.echo.EchoSe

                  rvice.context to org.jboss.osgi.framework.internal.SystemBundleContext

                   

                  Can you help me with this ?

                   

                  Thanks

                    As I said, please start from the working example.

                    Also, if you have a webapp issue - create a new thread instead of hijacking this ejb3 thread.

                      I am using Maven 3.0.3.

                       

                      Moreover doc says there are two bundles and wars are deployed but I don't see those are being generated. When I do mvn install or clean. So am I missing any step here.

                      The JavaEEIntegrationTestCase deployes two bundles

                      • example-javaee-api
                      • example-javaee-service

                      and two JavaEE archives

                      • example-javaee-ejb3
                      • example-javaee-servlet
