为什么这个代码不能查找（）JMS连接工厂？

标签： java jboss jms wildfly

我已经失败了一个多星期才学会了足够的JBoss / Wildfly 10来编写一个可以获得与Wildfly的JMS连接的java类。有人能指出我正确的方向吗？

该类在与Wildfly在同一台计算机上运行的Eclipse上执行。 （从技术上讲，这是一个远程连接？）

错误是：

javax.naming.CommunicationException    
Failed to connect to any server. 
Servers tried: [http-remoting://localhost:9990 
//Servers tried: [http-remoting://localhost:8080 depending on Context.PROVIDER_URL
(java.io.IOException: Unknown service name)]

我用这个命令启动Wildfly：

<wildfly-10.1.0.Final>\bin\standalone.bat --server-config=standalone-full.xml

Wildfly命令窗口摘录（如下）确认使用了standalone-full.xml。

还有一个工厂绑定到jndi名称：“java：jboss / exported / jms / RemoteConnectionFactory”

Wildfly控制台从

打开 
http://localhost:9990

代码中闪烁的用户ID和密码将其打开

我已经粘贴了下面的CLASS CODE，ECLIPSE CONSOLE OUTPUT和WILDFLY CONSOLE EXCERPTS。

我没有想法。希望有人能指出我正确的方向

答案 0 :(得分：0)

请检查ping localhost是否正在解析以纠正环回地址。我也遇到过ipv4 box上类似的问题，ping正在解决ipv6 loopback [:: 1]

在以下属性中尝试127.0.0.1而不是localhost

java.naming.provider.url＆＃34; http-remoting：// localhost：9990＆＃34;
