春天的NoClassDefFoundError [英] NoClassDefFoundError in spring

问题描述

我写了一个在Weblogic 10.3上运行的Spring应用程序。在这个应用程序中，我有一些JMS Queue使用者。

I wrote a Spring application which runs on Weblogic 10.3. In this application I have some JMS Queue consumers.

有时我在应用程序关闭或打开时遇到错误（我在两种情况下都看到了这个错误）说：

Sometimes I got an error when the application is closing or opening (I saw this error in both situation) saying:

    java.lang.NoClassDefFoundError: org/springframework/jms/connection/SmartConnectionFactory

        ... 6 more

为什么我会收到此错误，我该怎么做才能解决它？
spring.jar的版本是2.5.5

Why do I get this error and what should I do to solve it? The version of the spring.jar is 2.5.5

推荐答案

该异常意味着该类未被加载进入JVM。确保spring.jar位于Weblogic服务器的类路径或库文件夹中。

That Exception means that the class is not getting loaded into the JVM. Make sure that the spring.jar is in the Weblogic server's classpath or library folder.
