    AS7: "IllegalArgumentException: key is null"

    Wolfgang Knauf Master

      Hi to the JBoss gurus!

       

      I don't know whether this is the right place, but I did not want to spam the AS7 devel forum, so I try it here ;-):

       

      I picked AS7 from git today and tried to deploy a simple JavaEE5 EAR with one stateless bean and web and app client.

       

      Using the version which uses only annotations, I found that injection of an EJB will not work in a JSP (worked in AS5). Is this a "work to be done" feature or is it worth a bug report?

       

      Second problem: I have the same sample without annotations, just deployment descriptors. Here I saw this error on deploy:

       

      23:12:28,258 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.deployment.unit."Stateless.ear"."StatelessWeb.war".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.unit."Stateless.ear"."StatelessWeb.war".INSTALL: Failed to process phase INSTALL of subdeployment "StatelessWeb.war" of deployment "Stateless.ear"

          ... 4 more

       

      How shall I continue with such problems ;-)?

       

      The samples can be found here:

      -sample with annotations: http://www.cs.hs-rm.de/~knauf/KomponentenArchitekturen2008/stateless/Stateless.ear

      -sample without annotations, but deployment descriptors: http://www.cs.hs-rm.de/~knauf/KomponentenArchitekturen2008/stateless/StatelessNoAnnotation.ear

          This appears to be a bug. Can you file a JBAS JIRA please?

          You can even try the as7-dev mailing list https://lists.jboss.org/mailman/listinfo/jboss-as7-dev (since it's in development stages, I believe it's OK to post these issues in that list for now).

          Either the mailing list or even the #jboss-as7 IRC channel (irc.freenode.net server) is where you can ping us with such issues.

            Thanks!

             

            Issue filed: https://issues.jboss.org/browse/JBAS-9261

             

            I will try to find more useful information in the server.log for the EJB injection problem and will come back with it later.

              I encounter the same issue deploying my .war.  In my case, I have a datasource defined in my web.xml

               

              <resource-ref>

                  <res-ref-name>jdbc/MyDB</res-ref-name>

                  <res-type>javax.sql.DataSource</res-type>

                  <res-auth>Container</res-auth>

                  <res-sharing-scope>Shareable</res-sharing-scope>

                </resource-ref>

               

               

              in my jboss-web.xml, this:

              <resource-ref>

                  <res-ref-name>jdbc/MyDB</res-ref-name>

                  <jndi-name>jdbc/MyDB</jndi-name>

              </resource-ref>

               

              If I change the jndi-name in jboss-web.xml to java:/MyDB (along with the datasource configuration in standalone.xml) deploys and runs fine.

               

              <resource-ref>

                  <res-ref-name>jdbc/MyDB</res-ref-name>

                  <jndi-name>java:/MyDB</jndi-name>

              </resource-ref>

               

              To give you an indication of where you might start looking (e.g., @EJB beanName, lookup definitions).   Note also JBAS-9224 , targeted for Beta3 is intended to address issues such as these.

                Now I took a look at my other deployment problem: I see a "Stateless.ear.failed" file with this content:

                 

                "Failed to execute deployment operation in allowed timeout [60]"

                 

                The server.log contains only success messages:

                21:58:09,578 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-4) Starting deployment of "Stateless.ear"

                21:58:09,609 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-4) Starting deployment of "StatelessWeb.war"

                But at least the JSP page of the web project is working - just EJB injection did not happen...

                 

                One more JIRA ;-)?

                  Shelly, my sample has a stateless bean bound to a different JNDI name:

                   

                  jboss.xml of ejb jar:

                      <enterprise-beans>

                          <session>

                              <ejb-name>GeometricModelBean</ejb-name>

                              <jndi-name>Keks</jndi-name>

                              <local-jndi-name>KeksLocal</local-jndi-name>

                          </session>

                      </enterprise-beans>

                   

                  and the web project references it:

                  <jboss-web>

                      ...

                  Is this related to your situation?

                   

                  So I removed jboss.xml and jboss-web.xml, and now I see the same timeout as seen above with my first sample ;-)

                    Can't say for sure.  I've downloaded the sample apps from the JBAS-9261 and will test them later on to see what's going on.

                      Deploying StatelessNoAnnotation.ear results in missing dependencies for the ejb-refs.  So does seem similar to my issue with resource ref and variant of JBAS-9224.

                            Thanks. I tried to follow this thread, but it is a bit too deep in the AS internals for me ;-). Anyway, I subscribed to the devel list.

                             

                            One question: in my sample, I tried to change the global JNDI name of the EJB (same as a "@RemoteBinding" annotation would do):

                             

                            jboss.xml:

                            <jboss>

                                <enterprise-beans>

                                    <session>

                                        <ejb-name>GeometricModelBean</ejb-name>

                                        <jndi-name>Keks</jndi-name>

                                        <local-jndi-name>KeksLocal</local-jndi-name>

                                    </session>

                                </enterprise-beans>

                            </jboss>

                             

                            And in "jboss-web.xml", I tried to bind my EJB to this global name:

                            <jboss-web>

                                ...

                                <ejb-ref>

                                    <ejb-ref-name>ejb/GeometricModel</ejb-ref-name>

                                    <jndi-name>Keks</jndi-name>

                                </ejb-ref>

                             

                            As far as I can follow the mailing list discussion, this global binding is invalid. But how correct JNDI names look like? I tried to use "<jndi-name>java:Keks</jndi-name>" (and also "java:/Keks"), and didn't see an error message, but the app did not deploy either because of the "timeout" problem (see above)...  So I don't know whether I am on the right track...

                             

                            Your workaround in JBAS-9261 does not seem to handle the "@RemoteBinding" step as far as I see?

                             

                            Best regards

                              Right now, in AS7 we don't yet have support for jboss.xml deployment descriptor and also no support for JBoss EJB3 specific annotations. So even @RemoteBinding won't work. In AS7, we currently only support the EJB3.1 mandated jndi names for EJBs. So in your case, in the jboss-web.xml you can point to the EJB3.1 portable jndi name:

                               

                               

                              <jboss-web>
                                  ...
