Question

我尝试将commons-codec-1.10.jar放在/ TOMCAT / lib /文件夹中并运行Tomcat但是在启动applet时仍然会收到相同的错误消息。在Tomcat之外运行代码时，我不会得到相同的错误。这基本上是从旧版本的commons-codec-1.3.jar到commons-codec-1.10.jar的代码从DES更改为AES时的变化。

你是否包括apache commons项目lib，比如

commons-codec:commons-codec

commons-codec的GAV是

org.apache.commons.codec

但它的包名是

//Create
Session["name"] = value;

这个包名将与apache commons lib包名冲突，尝试更改commons-codec＆amp;的包名。将其生成为jar或将源代码导入项目。
