未找到 JWS 类错误 [英] JWS Class not found error

问题描述

我试图探索 JWS 的端到端工作方式，正在关注此博客.JWS 教程链接

最初得到未签名的 jar 错误"stackoverflow post- 现在可能已修复，但是现在找不到它的抛出类，尝试了多种方法，例如创建一个没有包的类等，但仍然无法正常工作.一个带有步骤等的新类

我不确定是不是版本兼容性问题.

Apache tomcat - 8.0.23Java -1.8.0_40-b26

解决方案

JWS 需要外部 jars 到 \lib\ext 目录下.

I was trying to explore how the JWS works end to end, was following this blog. JWS tutorial link

initially got "unsigned jar error" stackoverflow post- may be fixed now, but now its throwing class not found, tried multiple things like creating a class without package etc etc, but still its not working. A new class with the steps etc.

I am not sure if its some version compatibility issue or not.

解决方案

JWS needs the external jars to b in the \lib\ext directory.
