Java Security Class无法找到 [英] Java Security Class Couldn't be found

问题描述

当启动我的程序时，下一个错误弹出

When launching my program the next error pops out

java.lang.NoClassDefFoundError：无法初始化类javax.crypto.SunJCE_b

java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.SunJCE_b

这意味着这个类是缺少的，虽然我已经手动找到这个类，通过jar / ide工作，但不能通过服务。

which means this class is missing although I've found this class manually, works via jar/ide but doesn't works prefectly via service.

也许我需要做一些修改？但是哪个？
提前感谢

Maybe I need to make a few modifications? but which? Thanks in advance

推荐答案

我不知道这是否与 问题，但是由于我正在使用的JCE策略文件的版本，我遇到了完全相同的行为。

I don't know if this is relevant to your problem but I was experiencing the exact same behavior due to versions of the JCE Policy files I was using.

使用正确的无限力量加密版本为我解决了这个问题。我相信我可能不小心安装了Java 7的扩展，而不是6.（我正在使用Java 6编译）

Using the proper Unlimited Strength Cryptography Extenstions solved this issue for me. I believe I might have accidentally installed the extensions for Java 7 as opposed to 6. (I was using Java 6 for compilation)

对于Windows机器，应该安装在您安装的JDK的jre / lib / security文件夹中，例如：c：\program files\Java\jdk1.6.0_33\jre\lib\security

For a windows machine, they should be installed in the jre/lib/security folder of your installed JDK, for example: c:\program files\Java\jdk1.6.0_33\jre\lib\security
