    problems working with XA datasource

    Markus Reis Newbie

      Dear all,


      in my EJB3 SLSB (exposed as a WebService) I'd like to contact a Jackrabbit XA datasource, operate on it, and commit changes.

      The datasource is configured in server/default/deploy/jcr-ds.xml:

       <connection-factories>
       <tx-connection-factory>
       <jndi-name>jcr/local</jndi-name>
       <xa-transaction/>
       <rar-name>jackrabbit-jca-1.3.1.rar</rar-name>
       <connection-definition>javax.jcr.Repository</connection-definition>
       <config-property name="homeDir" type="java.lang.String">${jboss.server.data.dir}${/}jackrabbit</config-property>
       <config-property name="configFile" type="java.lang.String">classpath:repository.xml</config-property>
       <config-property name="bindSessionToTransaction" type="java.lang.Boolean">true</config-property>
       </tx-connection-factory>
       </connection-factories>
      


      my SLSB looks like:
      the field that contains the connection factory:
       @Resource(mappedName="java:jcr/local", type=javax.jcr.Repository.class, authenticationType=javax.annotation.Resource.AuthenticationType.CONTAINER) Repository repo;
      

      the method (excerpt) where operations are executed on the XA connection:
       Credentials cred = new SimpleCredentials(path.getUsername(), path.getPassword());
       session = repo.login(cred, null);
       Node root = session.getRootNode();
       Node child = root.hasNode(path.getRelativePath()) ? root.getNode(path.getRelativePath()) : createFilePath(root, path.getPathParts(), path.getObjectName());
       FileTypeResolver ftr = FileTypeResolver.instantiate();
       child.setProperty("jcr:mimeType", ftr.getMIMEType(obj));
       child.setProperty("jcr:data", new FileInputStream(obj));
       Calendar rightNow = Calendar.getInstance();
       child.setProperty("jcr:lastModified", rightNow);
       session.save();
      

      I annotated the method with:
       @TransactionAttribute(TransactionAttributeType.REQUIRED)
      

      This should be the default setting AFAIK, but who knows ...

      Debugging my code I found out that everything works fine until and after session.save() - When the method returns however it seems that a commit takes place (calling XASessionImpl.end()) and this commit is not successful due to a missing transaction:

      This topic may fit into the JCA or Transactions Forums as well, but it seems that it is somehow closely related to EJB3, since the same code works well from within a JSP page.

      Any help/guidance is highly appreciated.


      kind regards,
