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?!

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".

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
        at 
org.apache.xbean.naming.context.AbstractContext.lookup(AbstractContext.java:161)
        at 
org.apache.xbean.naming.context.AbstractContext.lookup(AbstractContext.java:611)

        at 
org.apache.openejb.core.ivm.naming.JndiUrlReference.getObject(JndiUrlReference.java:34)
This problem is common for my application and geronimo examples from 
official site.

Please, help me to understand this strange behaviour.

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