无法更改netbeans的默认起始页

Question

我在Netbeans中创建了一个名为test9的web应用程序。我在其中创建了各种jsp文件和servlet等。现在我想将起始页index.html更改为index.jsp，所以我创建了一个新文件index.jsp并删除了index.html，但在运行它之后，它仍然试图打开index.html并显示404错误资源未找到，我甚至在我的xml文件中进行了更改，但仍然在这样做。我还需要做一些其他的修改吗?

xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

Answer 1

在netBeans中，您可以右键单击项目，然后单击属性。将打开一个新的弹出窗口，在左侧菜单上将有一个标签调用run。点击这里，然后在"相对URL"中输入

/nameOfYourJspFile.jsp

和它工作，但我仍然不知道为什么

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

Answer 2

我知道这是一个旧的帖子，但是因为我有同样的问题并解决了它，所以我发布我的答案来帮助一些可能陷入这种情况的人。

对我来说有效的是将新的jsp文件从WEB-INF文件夹中取出。
