线程“main”org.owasp.esapi.errors.ConfigurationException 中的异常：

Question

import org.owasp.esapi.*;

public class esapiTest
{
public static void main(String args[])
{
test();
}
public static void test()
{
String clean = ESAPI.encoder().canonicalize("someString");
Randomizer r=ESAPI.randomizer();    
System.out.println(r);
System.out.println(".....................");
System.out.println(clean);
}
}

为什么我会在运行时收到这些错误？ 我正在使用 ESAPI-2.0.1.jar，我不想在服务器上运行它。 只是在 Eclipse 中测试它。 它们在我的构建路径和参考库中。 任何帮助都会很棒。 谢谢。
