Websphere JMS从远程客户端排队访问

养俊驰

2023-03-14

问题内容：

背景
我是PHP和前端Web开发人员，使用Netbeans在Java中开发应用程序以从Websphere（我认为是V8.5）JMS队列中进行读取，然后向适当的脚本/服务器发出命令。这是我10年来第一次使用Java进行专业学习，因此请多多包涵。我的初始测试应用程序在托管jms队列的服务器上运行良好，但是当尝试从远程位置进行连接时我遇到了一个接一个的错误（此刻恰好是Windows，但最终将是linux）。我一直在努力解决Java缺乏经验，诊断jar问题以及从Websphere和其他地方查找显然需要的jar的过程，但最终都遇到了麻烦。我已经看到很多答案，这些答案包括诸如“您需要正确的jar文件”之类的语句，而不是说哪个或您需要thisone.jar以及一个人引用的所有jar。我不知道如何找出应该的罐子。我读过一些帖子，说该过程仅适用于我的图书馆中的一些罐子。完全卡住了…

错误我没有运气的错误

 javax.naming.NamingException: Failed to initialize the ORB [Root

我正在做什么， 我已将以下罐子添加到库中

javax.jms-1.1.jar 
com.ibm.ws.orb_8.5.0.jar 
com.ibm.ws.ejb.thinclient_8.5.0.jar 
com.ibm.was.sib.client.thin.jms_8.5.0.jar 
com.ibm.was.admin.client_8.5.0.jar 
com.ibm.ws.messagingClient.ja

我还读到以下瓶子是必需的

sibc.jms.jar
sibc.jndi.jar
sibc.orb.jar

我已经找到了它们并也添加了它们，尽管我也读到如果您已经拥有瘦客户机，则不需要这些。

并正在使用JDK1.7

context factory: com.ibm.websphere.naming.WsnInitialContextFactory 
Provider URL: corbaloc:iiop:192.168.254.202:2809

正在创建上下文。但是无法建立队列工厂连接。我可以创建一个到ip地址的套接字并使用快速测试应用程序发布。

问题答案：

选中此选项- 使用WebSphere Application
Server安装和配置JMS瘦客户端
。

您现在需要的唯一罐子是：

com.ibm.ws.orb_8.5.0.jar 
com.ibm.was.sib.client.thin.jms_8.5.0.jar 
com.ibm.ws.ejb.thinclient_8.5.0.jar

因此，请从您的类路径中删除所有其他内容。并确保不仅在构建过程中，这些jar也在您的运行类路径中。

对于初始上下文，请尝试以下操作：

Hastable env = new Hastable();
env.put(Context.PROVIDER_URL,"iiop://localhost:2809");  // if using default ports
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
InitialContext ctx = new InitialContext(env);
