Gbean and EJBs
Hello,
I want to know if a Gbean that is in the same EAR with other EJBs, can
obtain the local interface of one of these EJBs.
thanks.

This absolutely definitely will not work. GBeans are lower-level
server components that aren't really expected to use jndi (for
instance the jndi system is set up with a few gbeans), and we
certainly don't provide jndi-based dependency injection through
annotations for them. You have to look up the ejb in jndi "by
hand". I would recommend using "new InitialContext()" if you can get
it to work since you can arrange for other things like datasources to
be available there as well, whereas with the openejb jndi system I
don't think datasources are available.

I doesn´t work. I can obtain EJB local interface. I think this lines work as
if I do new InitialContext() without parameters.
I would like to obtain the interface as we do with EJB 3.0. I try it adding
this lines to source code...
@EJB(name="TeamBeanRemote")
TeamRemote local=null;
-- and adding a ejb-ref to gbean tag as this:
<gbean name="TestGBean" class="com.test.SSEGBean">
<attribute name="port">4201</attribute>
<attribute name="host">localhost</attribute>
<ejb-ref>
<ref-name>TeamBeanRemote</ref-name>
<nam:pattern
xmlns:nam="http://geronimo.apache.org/xml/ns/naming-1.1">
<nam:artifactId>test_ejb3</nam:artifactId>
<nam:name>test_ejb3</nam:name>
</nam:pattern>
</ejb-ref>
</gbean>
.. but It doesn´t work. Can I use EJB3.0 annotations inside Gbean?

During "the simplest and easiest approaches" day everything should be
simplest and easiest (as well as intuitive) so your best bet would be
to look at gbean as any other java remote client and do the following:
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
Context ctx = new InitialContext(properties);
MyEjbBeanIntf myEjbBean = (MyEjbBeanIntf) ctx.lookup("MyEjbBeanLocal");
As the gbean's actually part of the server environment, I'd expect you
can leave off the Context.INITIAL_CONTEXT_FACTORY setting and look up
ejbs without it.

Hello,
How can Gbean obtain the global
jndi?

I haven't tried it but I expect you could look them up in global
jndi, probably under java:. I believe the names the ejbs are bound
to are logged as the ejb module is deployed.
hope I'm right :-)
