Eclipse - web应用程序Tomcat部署被借用

Question

任何帮助都将不胜感激。我正在运行一个web应用程序，它依赖于我工作空间中的另外两个项目。这两个项目进一步依赖于我工作区中的其他3个项目。工作区中的任何项目都没有错误。在Tomcat中运行web应用程序会产生以下错误：

java.lang.NoClassDefFoundError: com/tele/misc/DefaultApplicationModule

它是依赖项目的第一级中的一个类。直到最近，一切都运行得很好。这显然是某种类路径问题？对于如何在Eclipse元数据中找到并修复此问题，有什么建议吗？

所有这些都源于我的servlet上下文侦听器：

<!-- CRTool Context listener starts report processing Engine -->
<listener>
    <listener-class>za.co.huge.processor.CRToolContextListener</listener-class>
</listener>

在依赖项目的Guice模块上初始化时失败：

/* singleton design pattern - so only one service thread can be running */
private ReportProcessor(final long sleepTime){
    serviceThread = new ServiceThread(sleepTime);
    thread = new Thread(serviceThread);
    thread.setPriority(Thread.MIN_PRIORITY);
    final Injector injector = Guice.createInjector(new     DefaultApplicationModule());
//      final Injector injector = Guice.createInjector(new CommissionsModule(), new     DefaultApplicationModule());
//      ci = injector.getInstance(CommissionsImpl.class);
    }

编译代码后，程序中每个类的.class文件就结束了。这些二进制文件是Java解释以执行程序的字节码。NoClassDefFoundError指示负责动态加载类的类加载器找不到您试图使用的类的.class文件。它可能表明您在执行代码时没有设置类路径选项。此链接说明如何在执行时设置类路径。http://en.wikipedia.org/wiki/Classpath_%28Java%29
