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.provider.url", "foo://"  
+ 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 your var/log/ file

The output should look similar to the following:

INFO - Assembling app: /Users/dblevins/work/openejb3/itests/openejb-

There is an open issue (GERONIMO-2884) regarding the default jndi  
names you may want to check out if you names like "geronimo- 

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:

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.
