Problem with @Resource and JBOSS

[tamri]

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;

I have tryed, bat it is error "mappedName not found"

[anders.hedstrom]

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 "

[holeinone]

instead of mappedName try just "name" for instance:

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