背景我是 php 和前端 Web 开发人员，使用 Netbeans 开发 Java 应用程序，从 websphere（我认为是 V8.5）JMS 队列中读取数据，然后向适当的脚本/服务器发出命令。这是我大约 10 年来第一次主要接触 Java，所以请耐心等待。我最初的测试应用程序在托管 jms 队列的服务器上运行良好，但是当我尝试从远程位置（目前恰好是 Windows，但最终将是 Linux）连接时，我遇到了一个又一个错误。我一直在与缺乏 Java 经验、诊断 jar 问题以及从 websphere 和其他地方查找明显需要的 jar 的过程作斗争，但最终还是遇到了困难。我见过很多答案，其中包含诸如“您需要正确的 jar 文件”之类的语句，但没有说明哪些文件或您需要 thisone.jar 以及其中引用的所有 jar 文件。我不知道如何找出应该是什么罐子。我读过一些帖子，说这个过程应该只适用于我库中的一些罐子。我完全卡住了...

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
我还读到需要以下罐子
sibc.jms.jar
sibc.jndi.jar
sibc.orb.jar
我已经找到了这些并添加了它们，尽管我也读到如果您有我已经拥有的瘦客户端，则不需要这些。
我使用的是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。但我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进行发布。
The Code这是类文件和所有连接位。这是一项完整的工作正在进行中。
