每当我尝试使用JPA 2.0和Websphere运行更新查询时，我都会收到java.lang.ArrayStoreException。我正在使用测试实用程序，并且我成功更新了正确的行等等，没有事务被回滚，我只是得到了该异常并且我的应用程序没有执行。我怎么能解决这个问题...我不知道堆栈跟踪是否会对你有任何好处...但是因为这个ia堆栈溢出我以为我会把它发布给任何人...

每次查看异常时，我都会得到一些类型不匹配的建议吗？但我不知道是这样的。一切都好看......我错过了什么？有没有人知道为什么会发生这种异常？
答案 0 :(得分：1)
没有看到任何代码，我不得不说你混淆了你的类型。 http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/ArrayStoreException.html
您是否正在使用任何继承，对象或多态，并且不严格遵循这些类型？
我会从这里开始：
