dynamodb.jar 结构,在哪里 lib/ .jar s、 所有这些都是嵌套的 .震击器 需要 com.mparnisa.dynamodb.table .

发电机.jar

try {
    File file  = new File("<path>/dynamo.jar");

    URL url = file.toURI().toURL();
    URL[] urls = new URL[]{url};

    ClassLoader urlClassLoader = new URLClassLoader(urls);

    String resourceModelClassName = "com.mparnisa.dynamodb.table.ResourceModel";

    Class<?> resourceModelClass = urlClassLoader.loadClass(resourceModelClassName);
    Object resourceModel = resourceModelClass.newInstance(); // this works

    String resourceHandlerClassName = "com.mparnisa.dynamodb.table.CreateHandler";

    Class<?> resHandlerClazz  = urlClassLoader.loadClass(resourceHandlerClassName);
    try {
        Object resourceHandlerInstance = resHandlerClazz.newInstance();

    } catch (NoClassDefFoundError e) {
        System.out.println(e.getMessage());
    }
} catch (Exception e){
    System.out.println(e.getMessage());
}

代码与

java.lang.NoClassDefFoundError: com/amazonaws/AmazonServiceException

import 编辑 com.mparnisa.dynamodb.table.CreateHandler .

1. 我需要换衣服吗清单.MF所以 是否正确解决?
2. URLClassLoader 聪明到足以调查清单.MF对于 class-path ?
