【问题描述】：
我找不到 Java 独立客户端从 WildFly 获取有效 InitialContext 的简单代码示例。存在吗？
我放弃了 Glassfish 4，因为 Oracal 永远不会解决它的 JMS 问题（我需要 WildFly 的 Context 的真正原因。现在我在 WildFly 上失败了。
我相信一个简单的例子会帮助很多刚接触 WildFly 的人。 （注意：不是从企业容器中获取 WildFly 的上下文。从独立的 Java 客户端获取它——这样它就可以实现 JMS 消息传递。）
这是我所知道的最简单的代码。
次要相关问题：如何取消 Derby 不可用警告。每个人都说它需要 derbycleint.jar。 S0 我把它（和 derby-driver.jar）放在任何地方。仍然收到警告。
主要问题：我找不到 new IntialContext (env) 所需的一组属性。它似乎需要某种安全凭证。我只是找不到从哪里开始寻找和阅读以弄清楚我需要做什么。有什么帮助吗？ （我想找到有效的简单代码，因为它肯定会帮助其他 WildFly 新手入门。甚至添加 JMS 部分，因为 Glassfish 不适合这样做。）
代码：
package org.america3.wildfly.jms;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.sun.messaging.ConnectionFactory;
public class JMSSendAndReceive {
static Hashtable<String, String> jndiProperties = new Hashtable<String,String>() {
private static final long serialVersionUID = 1L;
{
put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
/*after posting I added these properties*/
put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
/*That produced CONSOLE 2 below for new result -- DERBY is gone!
I think all that's needed is to get
org.jboss.naming.remote.client.InitialContextFactory
into the Eclipse build path.
No luck. That led to adding addtional classes
... see commments below.
They led to CONSOLE 3 output that offers no hope at all.
I give up. Can anyone help?

}
};
static public void main (String[] args) {
System.out.println("AS_DERBY_INSTALL: " + System.getenv("AS_DERBY_INSTALL"));
System.out.println("JAVA_HOME: " + System.getenv("JAVA_HOME"));
try {
final Context context = new InitialContext(jndiProperties);
ConnectionFactory factory = (ConnectionFactory) context.lookup("java:comp/DefaultJMSConnectionFactory");
System.out.println(factory);
} catch (Exception e) {
System.out.println("Try Failed");
System.out.println(e.getClass().getName());
System.out.println(e.getMessage());
}
}
