Question

当我通过EJB接口查询实体时，在控制台下可以，但是从Swing切换到查询会抛出此异常。

例外：

Answer 1

事实证明这是一个JRE错误。因为我的控制台env是1.5而swing是1.6：

我们需要将此arguemnt传递给JVM

-Dsun.lang.ClassLoader.allowArraySyntax =真

Answer 2

当与JVM找到的序列化对象相对应的类与序列化类具有相同的serialVersionUid时，会生成此异常，但实际上是不同的版本（即：在不更改版本的情况下对类进行了更改） ID）。

检查类路径中是否有相关的jar / class文件？

例外：java.io.StreamCorruptedException：类型代码无效：00
