understand
this "feature".
EJB 1.1, EJB 2.x and EJB 3.0 standalone clients do work.
To connect to the server using the default settings:
Properties props = new Properties();
props.put("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
props.put("java.naming.provider.url", "foo://
127.0.0.1:" + port);
InitialContext context = new InitialContext(props);
The JNDI Names for each bean are printed in INFO in the
OpenEJB.startup log cagetory, which you can enable by adding this:
log4j.logger.OpenEJB.startup=INFO
..to your var/log/server-log4j.properties file
The output should look similar to the following:

There is an open issue (GERONIMO-2884) regarding the default jndi
names you may want to check out if you names like "geronimo-
deploymentUtil5840.tmpdir/FooBeanBusinessRemote.
Changing the format of the JNDI names is fine. The only drawback
is offical javaee 5 application-client.xml style clients will no
longer be able to look up ejbs (well, not using the java:comp/env
snytax anyway, they could still look them up as standalone
applications do). See the info on this page on how to reset the
openejb.jndiname.format system variable:
http://openejb.apache.org/jndi-names.html
The default value is "{deploymentId}/{interfaceClass}"
Hmmm... Looking at the code right now I see that its actually a
bit tricky to set the "openejb.jndiname.format" property --
normally setting it as a system property would do the trick, but I
see we're not checking to see if it was set before stuffing in the
default.
If you want to change the format, let me know and I will show you
a couple options.

David, thank you for your response, and.... please help :-)
I've configured connection to context with theese settings
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
properties.setProperty(Context.PROVIDER_URL, "ejbd://
localhost:4201");
this.ctx = new InitialContext(properties);
and try to get remote SB with method
this.ctx.lookup("EJBtest-1.0.jar/CustomerFacade");
and get instance of.... org.apache.openejb.client.JNDIContext..
where is my session bean?!
I think you need to append the name of the interface you are trying
to get. You could list the context to find out exactly what is bound
there.
There is CustomerFacade in JNDIViewer tree - Geronimo Console, but....
1) when I deploy my application the console prints warn like:
10:45:38,906 WARN [Runtime] The property named
"openjpa.ClassTransformerOptions" was not recognized and will be
ignored, although the name
closely matches a valid property called "openjpa.ClassResolver".
This is not a problem.
2) Although I set key log4j.logger.OpenEJB.startup to value INFO,
there's no jndi messages on console
3) May it be independent troublem, but I use persistence unit, with
properly configured (on server) connectio pool, and when I explore
(click) via jndi viewer, geronimo console prints error like
javax.naming.NotContextException: geronimo/env/
pl.netia.fonbsa.core.dao.facade.impl.CommonFacadeImpl/entityManager

org.apache.openejb.core.ivm.naming.JndiUrlReference.getObject

This problem is common for my application and geronimo examples
from official site.
entity managers are not bound to global jndi, so this is not
surprising. Can your session bean get its entity manager?
thanks

Please, help me to understand this strange behaviour.

PS. Let's changing jndi name format to near future.
