Post subject: Annotations usage
Hi,

I am working on EJB 3.0. How can we use @EJB and @Resource in MyEclipse?

hahagal ,

Just like you use other annotations , you can use @EJB too.Please take a look at these links for more information:

Hi swapna,

I am having problems with the @Resource annotation. The following codes is in session bean. I do not have any ejb-jar.xml or ejb-jar-bnd.xml files. I am using WebSphere 6.1 with ejb feature pack.

Code:

@Resource(name="jdbc/Default")
   private DataSource dataSource;
   
   //test connection
   public Connection getDatasourceConnection() {
      String _LOC = "[SB_ResourceBean: getDatasourceConnection]";
      System.out.println(_LOC + "1.0");
      Connection con = null;
        try {
           con = dataSource.getConnection();
           System.out.println(_LOC + "1.0 datasource " + con);
            return con;
        } catch (Exception e) {
           e.printStackTrace();
           return null;
        }
   }

Hi,

Any updates to this issue? I have tried many ways and still can't get the @Resource to work.

hahagal ,

I am afraid this is not a MyEclipse issue. I suggest you post to Websphere support forums for better support.

Sorry for inconvenience.

Hope this helps.
