ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>

，stateful的是

ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>?stateful

这个见https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI?_sscc=t
如果你的不是jboss项目，还要加jboss-client.jar，并且添加jboss-ejb-client.properties，具体格式见上面那个连接

补充：Java ,  Java EE
