SessionContext lookup
Hi,
What JNDI path should I use to lookup an EJB using a SessionContext
which has been injected:
@Stateless
public class TestBean implements TestLocal
{
@Resource
private SessionContext sessionContext;
public void test()
{
sessionContext.lookup("???");
}
}
I've tried different combinations without any success...
Thanks
Christian

Re: SessionContext lookup
Posted by David Blevins <da...@visi.com>.
That will also work. Currently the EJBs are underneath
"openejb:local/"+ jndiName. So if the beans JNDI name is
"OrangeLocal" it can be found under "openejb:local/OrangeLocal".
Note though that the LocalInitialContextFactory approach to looking up
beans is the recommended approach and guaranteed stable in future
releases and functionally equivalent to an "openejb:local/" lookup.
We can't guarantee that the locations of things under "openejb:" won't
change and it should be considered a stop-gap solution till the
portable global JNDI functionality is rolled out in Java EE 6 (JSR-316).
I was actually hoping we could skip the need for a proprietary global
namespace and go straight to the portable spec defined version, but
the discussion on that feature in the 316 group is still very much in
progress.

Ok... Would it be possible to do it using the new "openejb:" jndi url prefix?

Yes, that will give the namespace where you can lookup any ejb from
any app.

Ok but isn't there a global JNDI namespace in OpenEJB? Like in most
other Java EE implementations...

Doing 'new InitialContext()' is going to get you the same JNDI
namespace that sessionContext.lookup() gives you, so that won't work
for what you need.
You can use the LocalInitialContextFactory if you want to lookup any
bean deployed in the container system.
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
initialContext = new InitialContext(properties);
That will bypass the bean's private jndi namespace and hook you up
with the generic "client" namespace.

Hi David,
I already know this method but I need to inject (lookup) ejbs
dynamically so it is useless for me...
I guess my only choice left is to use the 'new InitialContext()' alternative?

Re: SessionContext lookup

Hi Christian,
Try this:
@Stateless
public class OrangeBean implements OrangeLocal
{
public String echo(String s)
{
return s;
}
}
@EJB(name="orange", beanInterface = OrangeLocal.class)
@Stateless
public class TestBean implements TestLocal
{
@Resource
private SessionContext sessionContext;
public void test()
{
OrangeLocal orangeLocal = (OrangeLocal)
sessionContext.lookup("orange");
}
}
The @EJB annotation declares a reference to the Orange bean. The
sessionContext.lookup is a convenience method around 'new
InitialContext().lookup("java:comp/env/"+name)' and by default the
'java:comp/env' namespace is empty unless references are declared via
annotation or xml.
