从容器中在Websphere中查找EJB

Question

我在websphere中部署了一个ejb模块（EAR1），并希望从WAR访问该ejb，WAR也在同一websphere中部署。

我已经尝试使用以下代码，但不起作用。

public class RACAccessProvider {
    private InitialContext myInitialContext;
    public synchronized Object locateEJB(final Class clazz) throws ClassCastException, NamingException {
        try {
            System.out.println("looking up ejb.. for class " + clazz);
            Object obj;
            final String jndiName = clazz.getName();
            obj = myInitialContext.lookup(jndiName);
            System.out.println("###lookuop object.." + obj);
            return obj;
        } catch (final Exception e) {
            e.printStackTrace();
        }
        return null;
    }
    public RACAccessProvider() {
        System.out.println("Setting context in RACAccessProvider constructor...");
        final Properties context = new Properties();
        context.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
        try {
            myInitialContext = new InitialContext(context);
        } catch (NamingException e) {
            e.printStackTrace();
        }
    }
}

上面的代码挂在线上

obj = myInitialContext.lookup(jndiName);

非常感谢您的帮助。

you need to check if your jndi name is correctly mentioned,
Also if initial context is initialized properly as per below code:
InitialContext ic = new InitialContext();
String snName = "java:comp/env/mail/your_jndiname";
Session session = (javax.mail.Session)ic.lookup(snName);
