Hi!
I'm trying to build and deploy a small entity bean with OpenEJB. Now
there
is some trouble receiving a DataSource. What I did so far: I
configured the
data source in openejb.xml (as Connector and Recource), added a
resource-ref
to ejb-jar.xml, and tried to fetch it via JNDI. I varied this very
often,
searching through the list and web for hints, with no success. If I
browse
the context, I find my beans but no data source object or any other
resource.
How do I get my data source into the context?
I have no persistence.xml, since I don't use CMP. Is that correct,
or what
must it contain for BMP?
I have no openejb-jar.xml either. It is neccessary? Session beans
works
fine. What to put there?
Hi Alexander,
If you can post some information from your openejb.log, the resource-
ref declaration, and the jndi name you're looking up we can take a look.
You shouldn't need an openejb-jar.xml if you gave your openejb.xml
<Resource> and ejb-jar.xml <resource-ref> the same name (or even if
they end in the same name). For example, this should work
automatically:
--openejb.xml--
<openejb>
<Resource id="Orange" type="DataSource">
...
</Resource>
</openejb>
---------------
--ejb-jar.xml--
<ejb-jar>
...
<resource-ref>
<res-ref-name>jdbc/Orange</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
...
</ejb-jar>
---------------
Technically, we'll look for a Resource with id "jdbc/Orange" first,
but not finding that we'll scrape off the prefix and look for a
Resource with "Orange" as the id. With the above ref you should be
able to look up the datasource in the bean that declared it as follows:
InitialContext context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("java:comp/env/
jdbc/Orange");
With the above setup you should see something like this in the log:
INFO - Configuring Service(id=Orange, type=Resource, provider-
id=Default JDBC Database)
...
INFO - Auto-linking resource-ref 'jdbc/Orange' in bean YourBmpBean
to Resource(id=Orange)
Hope this helps!
