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。

尝试这里提到的Hello.java示例： -

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

但我在运行此文件时遇到这些错误： -

看起来你错过了：

qpid-common-0.10.jar

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

获取

或

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

如果你正在使用maven。

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