从独立代码

Question

我在WebSphere上的Rational Application Developer配置队列访问一个队列，采用了“V5默认消息提供者”和Websphere6.1

我现在尝试使用一个独立的应用程序来访问它（ JUnit测试），以便在其中添加一些消息。我目前使用下面的代码：

 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"); 

在最后一行我得到以下异常：

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？ 为了实现这一目标，我将ws_runtime.jar添加到了类路径中，我在RAD安装中找到了它。

Answer 1

您可能想要检查您在类路径中具有哪些JAR。粗略的一瞥表明某处存在不匹配。这条线：

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

告诉你，com.ibm.websphere.pmi.reqmetrics.PmiReqMetrics.register方法试图调用isAnyTracingElementEnabled方法上TraceComponent，但TraceComponent没有该方法。我猜测那个有TraceComponent的JAR是错误的。
