    Problem with @Resource and JBOSS

      I have a sessionBean and a call a datasource so
      @Resource
      public DataSource myDB;
      when I run a jboss (jboss-4.0.4.CR2) it thows exception :

      java.lang.RuntimeException: You did not specify a @Resource.mappedName() on publ
      ic javax.sql.DataSource svr.SessionItemInfoBean.datasource and there is no bindi
      ng for that enc name in XML.

      after that I write @Resource(mappedName="DS"), this code shows that @Resource has't attribute mappedName.

      What can I do? I want to use @Resource to inject
      DataSource . Enyone knows how can I do?

          Try

          @Resource(mappedName="java:<your-jndi-name>")
protected DataSource ds;

              Are you sure your using the correct jndi name?

              I'm using jboss-4.0.4.CR2 as well, and here's how I do it:

              I got the following line in my -ds.xml file:

              <datasources>
 <local-tx-datasource>
 <jndi-name>jdbc/MyDS</jndi-name>
...


              and I got the following code in my EJB; 

              @Resource(mappedName="java:jdbc/MyDS")
protected DataSource ds;


              And it works fine...

                  I have so in -ds.xml

                  <local-tx-datasource>
                  <jndi-name>jdbc/MSSQLDS</jndi-name>
                  and
                  @Resource(mappedName="java:jdbc/MSSQLDS") protected DataSource ds;

                  you see it is the same, what you has written, bat I don't understand why is error on keywords "mappedName "

                    instead of mappedName try just "name" for instance:

                    @Resource(name="java:/QueueConnectionFactory")
                    private javax.jms.QueueConnectionFactory connectionFactory;
