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 队列中读取，然后向适当的脚本/服务器发出命令。这是我大约 10 年来第一次主要使用 Java，所以请多多包涵。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，但在尝试从远程位置(目前恰好是 Windows，但最终将是 Linux)连接时，我一直遇到一个又一个错误。我一直在为缺乏 Java 经验、诊断 jar 问题和从 websphere 和其他地方找到明显需要的 jar 的过程而斗争，但最终遇到了困难。我见过很多答案，其中包含诸如“您需要正确的 jar 文件”之类的陈述，但没有说明哪些或者您需要 thisone.jar 以及一个引用的所有 jar。我不知道如何找出应该是什么 jar 。我读过一些帖子说这个过程应该只适用于我库中的一些 jar 。我完全卡住了...
错误 我没有运气通过的错误

我在做什么 我已将以下 jar 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
我还读到需要以下 jar
sibc.jms.jar
sibc.jndi.jar
sibc.orb.jar
我已经找到并添加了它们，尽管我还读到如果您拥有我已经拥有的瘦客户端，则不需要这些。
我正在使用 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。

最佳答案
检查这个 - Installing and configuring the Thin Client for JMS with WebSphere Application Server .
你现在唯一需要的 jar 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
所以请从你的类路径中删除所有其他的。 并确保这些 jar 也在您的运行类路径中，而不仅仅是在构建期间。
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);
