Java 在Tomcat'中找不到带有JAR的类；s库目录

我可能遗漏了一些非常明显的东西，或者情况非常奇怪：

我有一个Ant构建文件来编译一组类，然后将这些类及其依赖项打包到uber jar中。它工作得非常好，生成的jar保存在TOMCAT/lib目录中，TOMCAT启动也非常好

现在，大约3天前，我添加了Bouncy Castle 1.52依赖项，之后构建文件创建了jar，它保存在TOMCAT/lib中，在TOMCAT启动期间，我得到了非常持久的ClassNotFoundError，而类实际上在jar文件中，它在TOMCAT/lib中

我无法理解这种情况，是JAR文件在构建过程中被破坏了，还是uber jarred的类不兼容

当我从eclipse导出一个“runnable jar”时，上述问题就不会发生

我在下面给出Ant构建文件：

下面是反编译类的屏幕截图：

public class DistributedCacheManagerFactory implements ObjectFactory {

protected static DistributedCacheManager distributedCacheManager;

static{

    distributedCacheManager=DistributedCacheManager.getDistributedCacheManager();

}//static block closing

@Override
public Object getObjectInstance(Object arg0, Name arg1, Context arg2, Hashtable<?, ?> arg3) throws Exception {

    return distributedCacheManager;

}//getObjectInstance closing

下面是反编译类的源代码：

public class DistributedCacheManagerFactory implements ObjectFactory {

protected static DistributedCacheManager distributedCacheManager;

static{

    distributedCacheManager=DistributedCacheManager.getDistributedCacheManager();

}//static block closing

@Override
public Object getObjectInstance(Object arg0, Name arg1, Context arg2, Hashtable<?, ?> arg3) throws Exception {

    return distributedCacheManager;

}//getObjectInstance closing

公共类DistributedCacheManagerFactory实现ObjectFactory{ 受保护的静态DistributedCacheManager DistributedCacheManager； 静止的{ distributedCacheManager=distributedCacheManager.getDistributedCacheManager（）； }//静态闭塞 @凌驾 公共对象getObjectInstance（对象arg0、名称arg1、上下文arg2、哈希表arg3）引发异常{ 返回分布式缓存管理器； }//getObjectInstance关闭

---

}//类关闭

堆栈跟踪？还有，找不到哪个类？@ChristopherSchultz，编辑了上面的文章，在启动时，所有Tomcat资源工厂都找不到。使用JAD来反编译eclipse生成的类，输出看起来是一样的。此外，在构建过程结束后，在jaring之前对类进行反编译，结果看起来是一样的。您可以使用

jar

解压

.jar

文件吗？事实上，7-Zip可以处理该文件并不重要。@ChristopherSchultz，我使用了windows命令提示符“jar-ie:\generalJunk\build\platform\vampire\jar\vp\u platform\u core.jar”中的以下命令，并尝试用“-t”列出jar的内容，命令挂起。看起来“jar”无法打开归档文件，您的观察结果非常好。
