how to use openejb.embedded.remoteable in TomEE
I am new to OpenEJB.
I have deployed a legacy EJBModule several different ways, with varying degrees of success:
1. deployed myEJB.jar to OpenEJB standalone server. Accessed the EJB's remotely from a webapp and a java client.
This works fairly well, although I haven't achieved 100% success from all clients.
2. installed TomEE, deployed myWebApp.war to TomEE, with myEJB.jar in myWebApp/WEB-INF/lib.
I am able to access the EJB's from the webapp using both LocalInitialContextFactory and RemoteInitialContextFactory,
but I can't access the EJB's from the java client using RemoteInitialContextFactory.
When I attempt to access an EJB from the client (on the same computer), I get this error:
In CLIENT'S STDERR.LOG:
org.apache.openejb.client.StickyConnectionStrategy connect
WARNING: Failover: Cannot connect to server(s):ejbd://localhost:4201 Exception: Cannot connect to server 'ejbd://localhost:4201'.
Check that the server is started and that the specified serverURL is correct.. Trying next.
In CLIENT'S STDOUT.LOG:

* I access this same bean from the webapp without any problem.
* I get a similar error when I try this provider URL: http://localhost:4204/ejb
I'm guessing it has to do with either or both of these:
1. openejb.embedded.remoteable (where does this property go? How do I tell if openejb is finding it?)
2. hostname/ipaddress that openejb binds to?
Can anyone shed some light on this problem?

That's too easy!
Now why didn't I think of that!?
Works great; Problem solved. Thank you both, Romain and Jonathan!

I think all you need to do is use http://localhost:8080/openejb/ejb as the

Properties p = new Properties();
p.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
p.setProperty(Context.PROVIDER_URL, "http://localhost:8080/openejb/ejb");
InitialContext ic = new InitialContext(p);
Hope that helps.

Thanks Vishwa. I seem to be lacking visiting the website more often :)

http://openejb.apache.org/3.0/clients.html I guess referring to this link

Is this somewhere on the website? I think we should add it if it's
not. I volunteer to add it, but am asking for the place and moreover a
confirmation that it's not already there.

Hi Frank,
I think all you need to do is use http://localhost:8080/openejb/ejb as the
provider URL (swap 8080 for your http port if its different):
Properties p = new Properties();
p.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
p.setProperty(Context.PROVIDER_URL, "http://localhost:8080/openejb/ejb");
InitialContext ic = new InitialContext(p);
Hope that helps.

hi,
in tomcat/tomee we use openejb webapp to do it, try http://localhost:<tomcat
port - probably 8080>/openejb/ejb/
