Configure datasource mapping

[sandello]

How I cat configure datasource mapping?

My stateless bean (ejb3) have this strings:

@Stateless(name="StatLoaderSEJB3")
@RemoteBinding(jndiBinding="StatLoaderSEJB3")
public class StatLoaderSEJB3 implements IStatLoader{
...
 @Resource(name="java:comp/env/jdbc/StatDS")
 private DataSource ds=null;
...
}

There is global datasource "java:/RadiusDS"

I tried to configure resource mapping via jboss.xml:

<?xml version='1.0' encoding='UTF-8'?>
<jboss>
 <enterprise-beans>
 <session>
 <ejb-name>StatLoaderSEJB3</ejb-name>
 <resource-ref>
 <res-ref-name>java:comp/env/jdbc/StatDS</res-ref-name>
 <jndi-name>java:/RadiusDS</jndi-name>
 <!--<res-type>javax.sql.DataSource</res-type>-->
 </resource-ref>
 </session>
 </enterprise-beans>
</jboss>

When I deploy myapp.ejb3 to Jboss, I saw there message:

15:37:59,803 WARN [ResourceHandler] Unbound injected resource interface javax.sql.DataSource ds

What I did whong?

I think

@Stateless(name="StatLoaderSEJB3")
@RemoteBinding(jndiBinding="StatLoaderSEJB3")
public class StatLoaderSEJB3 implements IStatLoader{
...
 @Resource(name="jdbc/StatDS")
 private DataSource ds=null;
...
}

<?xml version='1.0' encoding='UTF-8'?>
<jboss>
 <enterprise-beans>
 <session>
 <ejb-name>StatLoaderSEJB3</ejb-name>
 <resource-ref>
 <res-ref-name>jdbc/StatDS</res-ref-name>
 <jndi-name>java:/RadiusDS</jndi-name>
 <!--<res-type>javax.sql.DataSource</res-type>-->
 </resource-ref>
 </session>
 </enterprise-beans>
</jboss>

should work.


You can also do enc to global jndi mapping using @Resource.mappedName directly:

@Stateless(name="StatLoaderSEJB3")
@RemoteBinding(jndiBinding="StatLoaderSEJB3")
public class StatLoaderSEJB3 implements IStatLoader{
...
 @Resource(name="jdbc/StatDS", mappedName="java:/RadiusDS")
 private DataSource ds=null;
...
}

I tried both cases.
1. Nothing changed
2. error: cannot find symbol method mappedName()

If I use

@Resource(name="java:/RadiusDS")

all work rightly

How I can view JNDI namespace of my ejb3 module? Jboss service JNDIView don't display it (because StatLoaderSEJB3 local namespace is empty?).

[kabirkhan]

Which version are you using? There have been some changes in the spec, so what I have put should work with the latest release. If not, definitely with the next.

"Your way" is how it worked before.

CVSTag=JBoss_4_0_3_SP1 date=200510231751

[sandello]

I downloaded EJB3.0RC3 ?nd installed it in JBoss 4.0.3sp1
Now, this is work

...
 @Resource(name="jdbc/StatDS", mappedName="java:/RadiusDS")
 private DataSource ds=null;
...

but, if I try to configure mapping via jboss.xml

 <session>
 <ejb-name>StatLoaderSEJB3</ejb-name>
 <resource-ref>
 <res-ref-name>jdbc/StatDS</res-ref-name>
 <jndi-name>java:/RadiusDS</jndi-name>
 <!--<res-type>javax.sql.DataSource</res-type>-->
 </resource-ref>
 </session>

I get expetion
