Answer 4

java.lang.ClassCastException: [Ljava.lang.Object;
多了一个方括号

Answer 5

java.lang.ClassCastException: [Ljava.lang.Object;
at org.apache.jsp.blog.system.pictrue_jsp._jspService(pictrue_jsp.java:263)
pictrue.jsp页面有问题啊，是否有“[L”字符串；
如果是tomcat发布的话，到tomcat\work\Catalina\localhost\发布包名\org\apache\jsp下面找到
pictrue_jsp.java的263行

Answer 6

你想要强制转换的是什么类型? 
你要转换的这个对象实际上是一个对象数组
你是不是想要取这个数组里面的一个元素进行强制转换？ClassType ct = (ClassType)arr[0];
