OK, try this:
set GERONIMO_OPTS="-Dopenejb.jndiname.format={ejbName}/{interfaceClass}
geronimo.bat start

2009/6/3 Rodger <eternaljian@gmail.com>
I tried it.But the default format--{ejbName}{interfaceType.annotationName}
still works,the format doesn't change to
{ejbName}/{interfaceClass}.
That is
initialContext.lookup("CalculatorRemote"); works
but
initialContext.lookup("Calculator/org.apache.geronimo.samples.slsb.calculator.CalculatorRemote");  failed.

There are my ejb part:
@Remote
interface CalculatorRemote

@Stateless
class Calculator implements CalculatorRemote
