背景 我是php&前端Web开发人员使用Netbeans在Java中开发应用程序,从websphere(我认为是V8.5)读取JMS队列,然后向适当的脚本/服务器发出命令。这是我第一次使用Java大约10年,所以请耐心等待。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,但是当我尝试从远程位置(目前恰好是windows但最终将是linux)进行连接时,我一直遇到一个错误。我一直在努力解决我缺乏Java经验,诊断jar问题的过程,以及从websphere和其他地方找到明显需要的罐子,但最终达到了一堵砖墙。我已经看到很多答案,包括诸如&#34之类的陈述;你需要正确的jar文件",但不是说哪些或者你需要thisone.jar和所有引用的罐子。我不知道如何找出应该是什么罐子。我看过帖子说这个过程应该只适用于我库中的一些罐子。我完全陷入了困境......

我在做什么 我已将以下罐子添加到库
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
我找到了这些并添加了它们,虽然我也读过如果你有我已经拥有的瘦客户机就不需要这些。
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。但是我无法建立队列工厂连接。我可以创建一个ip地址的套接字并使用快速测试应用程序发布。
代码 这是类文件和所有连接位。这是完整的工作正在进行中。

选中此项 - Installing and configuring the Thin Client for JMS with WebSphere Application Server。
您现在唯一需要的罐子是:
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
所以请从类路径中删除所有其他内容。 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);

更新 /etc/resolv.conf 文件(在 Linux 上)并将域名添加到搜索参数中,让操作系统尝试解析主机名、添加域名并调用 DNS。如果 IP 地址随时间发生变化,您的系统将继续能够将无域主机名解析为正确的 IP 地址。
例如:对于主机名“jmsserver”
Content of /etc/resolv.conf:
domain mydom.com
nameserver 192.168.1.250
search xyz.com good.com what.ever.ca
如果 jmsserver 在 good.com 上,操作系统将使用 DNS 并尝试解析 jmsserver.mydom.com、jmsserver.xyz.com< /em>,将在 jmsserver.good.com 上成功获取 IP 地址以路由到目的地。
