java - 线程 "main"java.lang.NoClassDefFoundError : org/apache/qpid/url/URLSyntaxException 中的异常

Question

我在 Eclipse 和 Tomcat 中使用 QPid。创建动态 Web 应用程序并设置 QPID_HOME、QPID_WORK 环境变量。

尝试此处提到的 Hello.java 示例:-

https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/client/example/

但是我在运行这个文件时遇到了这些错误:-

看起来你不见了:

qpid-common-0.10.jar

可从 http://qpid.apache.org/download.html 获得

或

<dependency>
   <groupId>org.apache.qpid</groupId>
   <artifactId>qpid-common</artifactId>
   <version>0.10</version>
</dependency>

如果您使用的是 maven。
