Question

jndi.properties密钥的可能属性名称是什么？我找不到关于所有可能的关键名称的文档。

如何为jndi.properties输出主体，凭证和远程键/值对？

-run:
     [java] Sep 12, 2014 6:36:43 PM dur.bounceme.net.remotelookup.RemoteLookup run

可以看出，并非所有的键/值对都在输出。为什么？

对于“远程”名称和值，是否应该放在不同的属性文件中？

主要课程：

package dur.bounceme.net.remotelookup;

import java.util.Enumeration;
import java.util.Properties;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class RemoteLookup {

    private static final Logger log = Logger.getLogger(RemoteLookup.class.getName());
    private final MyProps p = new MyProps();

    public static void main(String... args) {
        try {
            new RemoteLookup().run();
        } catch (NamingException ex) {
            Logger.getLogger(RemoteLookup.class.getName()).log(Level.SEVERE, ex.getExplanation(), ex);
        }
    }

    private void run() throws NamingException {
        Properties jndi = p.getJNDI();
        Enumeration e = jndi.propertyNames();
        while (e.hasMoreElements()) {
            String key = (String) e.nextElement();
            String val = jndi.getProperty(key);
            log.info(key + "\t" + val);
        }
        Context ic = new InitialContext();
//        MyRemote mr = (MyRemote) ic.lookup("java:comp/env/ejb/Foo");  //
    }
}

读取属性文件，已经过去了：

package dur.bounceme.net.remotelookup;

import java.io.IOException;
import java.util.Properties;
import java.util.logging.Level;
import java.util.logging.Logger;

public class MyProps {

    private static final Logger log = Logger.getLogger(MyProps.class.getName());
    private final Properties jndi = new Properties();

    public MyProps() {
        try {
            loadJNDI();
            String name = jndi.getProperty("name");
        } catch (IOException ex) {
            Logger.getLogger(MyProps.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    public Properties getJNDI() {
        return jndi;
    }

    private void loadJNDI() throws IOException {
        jndi.load(MyProps.class.getResourceAsStream("/jndi.properties"));
    }

}

更重要的是，键的名称应该是什么？

您需要在JNDI documentation page上查看每个提供商（在您的情况下为COSNaming提供商）的文档。
