独立Java客户端如何获取Wildfly初始上下文？

标签： java java-ee wildfly wildfly-8

我找不到Java独立客户端从WildFly获取有效InitialContext的简单代码示例。它存在吗？

我放弃了Glassfish 4，因为Oracal永远不会修复它的JMS问题（我需要WildFly的背景的真正原因。现在我没有使用WildFly。

我确定一个简单的例子可以帮助很多新手使用WildFly。 （注意：没有从Enterprise容器获取WildFly的Context。从独立的Java客户端获取它 - 因此它可以实现JMS消息传递。）

这里的代码很简单，因为我知道如何制作它。

次要相关问题：如何杀死Derby不可用的警告。每个人都说它需要derbycleint.jar。 S0我把它（和derby-driver.jar）放在任何地方。仍然得到警告。

主要问题：我无法找到新的IntialContext（env）所需的一组属性。它似乎需要某种安全凭证。我无法找到从哪里开始查看和阅读以找出我需要做的事情。有帮助吗？ （我希望找到有效的简单代码，因为它肯定会帮助其他WildFly新手开始。甚至添加JMS部分，因为Glassfish已经不合适了。）

CODE：

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());
    }
  }

你可以尝试这些，它们主要是JBoss，但它和wildfly一样：

或
