访问来自独立代码队列

Question

我在为WebSphere的合理应用开发者构成的队列，使用“V5默认消息提供”和Websphere6.1

我现在尝试使用一个独立的应用程序（JUnit测试）来访问它，为了把一些信息在里面。我目前使用以下代码：

        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY,
                "com.ibm.websphere.naming.WsnInitialContextFactory");
        env.put(Context.PROVIDER_URL, "corbaloc::localhost:2809"); 
        InitialContext ctx = new InitialContext(env);

        javax.jms.Queue queue = (javax.jms.Queue) ctx.lookup("Topic");

在最后一行出现以下异常：

javax.naming.NamingException: The JNDI operation "lookupExt"on the context "vwagwolot0awNode01Cell/nodes/vwagwolot0awNode01/servers/server1" with the name "Topic" failed.  Please get the root cause Throwable contained in this NamingException for more information.  Root exception is java.lang.NoSuchMethodError: com.ibm.ejs.ras.TraceComponent: method isAnyTracingEnabled()Z not found

任何提示，我可以为了解决这个问题呢？ 为了得到那么远，我添加了ws_runtime.jar到类路径，这是我在RAD安装在什么地方找到。

Answer 1

您可能要检查你的类路径上，其JAR文件。粗略地看一眼某处表示不匹配。这一行：

java.lang.NoSuchMethodError: com.ibm.ejs.ras.TraceComponent: method isAnyTracingEnabled()Z not found

时告诉您com.ibm.websphere.pmi.reqmetrics.PmiReqMetrics.register方法试图呼吁isAnyTracingElementEnabled的TraceComponent方法，但TraceComponent没有该方法。我猜测，在已TraceComponent的JAR是错误的一个。
