public class veriçekmek {

    public static void main(String[] args) throws Exception {

        WebClient web=new WebClient();
        HtmlPage sayfa=web.getPage("http://www.idefix.com");

当我运行这个程序时，我得到这样的错误

 Exception in thread "main" java.lang.NoClassDefFoundError: javax/crypto/SecretKey

Answer 1

javax.crypto 包包含在 jce.jar 中，可以在 JRE 的 "lib" 文件夹下找到。将它添加到您的类路径中，您应该没问题。

有关类路径的详细信息，请参阅： http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html

Answer 2

我通过安装来自 https://jdk.java.net 的新参考 jdk 解决了这个问题。

无论出于何种原因，这些构建包括 oracle 构建中缺少的加密 jar。
