我真的很新的网页开发......我想借鉴JSP区域图（这是实践version..later上，我必须做出计划，从数据库中读取数据），当我尝试运行我得到下面的错误代码，我不知道如何解决这个问题... :(碧玉/ jfreechart的异常错误

谢谢提前！

编辑：

如果我删除PlotOrientation.VERTICAL ..我得到这个错误是相同的东西？ ; /我真的不知道我做错了什么:(

如果你看一下错误，你是在传递错误的量的参数您传递以下：

(String, String, String, CategoryDataset, PlotOrientation, boolean, boolean, boolean)

它期待下面的参数，而不是：

(String, String, String, CategoryDataset, boolean, boolean, boolean)

取出PlotOrientation和它应该摆脱那个错误。

我仍然得到同样的错误:(这个错误是什么做的语法？我认为这是关于Apache的，因为它说org.apache错误......（对不起，我真的很新的，努力工作，我的方式） – user1516649

这是整个堆栈跟踪还是还有更多？ – Lipongo
