Question

I am using following jars- commons-validator-1.4.0 ; commons.logging-1.2 ; commons.digester-1.8 ;commons.beanutils-1.8.3 commons.collections-3.2.1

but keeps on getting same error at line -

 Caused by: java.lang.ClassNotFoundException: org.apache.commons.digester.Rule
 at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
    at java.net.URLClassLoader$1.run(URLClassLoader.java:355)

              com.google.appengine.tools.development.IsolatedAppClassLoader.loadClass(IsolatedAppClassLoader.java:216)

    InputStream in = this.getClass().getResourceAsStream("validator-name-required.xml");
// Create an instance of ValidatorResources to initialize from an xml file.
  ValidatorResources resources = new ValidatorResources(in);

Answer 2

看起来好像找不到“ org.apache.commons.digester.Rule”类，摘要器的2.1版具有Rule.class，请下载此版本并尝试。
