Below is a simple example demonstrating how to construct a basic homepage using these two files.<\/p>\n<p>First, create a file named &#8220;web.xml&#8221; and place it in the &#8220;WEB-INF&#8221; directory of the project. In the web.xml file, we need to define a welcome file named &#8220;index.jsp&#8221; so that when users access the root directory of the application, the server will automatically load that page. Here is an example of the content of a web.xml file:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-meta\">&lt;?xml version=<span class=\"hljs-string\">\"1.0\"<\/span> encoding=<span class=\"hljs-string\">\"UTF-8\"<\/span>?&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">web-app<\/span> <span class=\"hljs-attr\">xmlns:xsi<\/span>=<span class=\"hljs-string\">\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\"<\/span>\r\n    <span class=\"hljs-attr\">xmlns<\/span>=<span class=\"hljs-string\">\"http:\/\/xmlns.jcp.org\/xml\/ns\/javaee\"<\/span>\r\n    <span class=\"hljs-attr\">xsi:schemaLocation<\/span>=<span class=\"hljs-string\">\"http:\/\/xmlns.jcp.org\/xml\/ns\/javaee http:\/\/xmlns.jcp.org\/xml\/ns\/javaee\/web-app_4_0.xsd\"<\/span>\r\n    <span class=\"hljs-attr\">id<\/span>=<span class=\"hljs-string\">\"WebApp_ID\"<\/span> <span class=\"hljs-attr\">version<\/span>=<span class=\"hljs-string\">\"4.0\"<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">display-name<\/span>&gt;<\/span>JavaWebExample<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">display-name<\/span>&gt;<\/span>\r\n    \r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">welcome-file-list<\/span>&gt;<\/span>\r\n        <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">welcome-file<\/span>&gt;<\/span>index.jsp<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">welcome-file<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">welcome-file-list<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">web-app<\/span>&gt;<\/span>\r\n<\/code><\/pre>\n<p>Next, create a JSP page named &#8220;index.jsp&#8221; and place it in the root directory of the project. In the index.jsp page, we can write any HTML, CSS, and JavaScript code to structure the content of the page. Here is an example of a simple index.jsp page:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-meta\">&lt;!DOCTYPE <span class=\"hljs-keyword\">html<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">html<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">head<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">meta<\/span> <span class=\"hljs-attr\">charset<\/span>=<span class=\"hljs-string\">\"UTF-8\"<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">title<\/span>&gt;<\/span>Java Web Example<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">title<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">head<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">body<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">h1<\/span>&gt;<\/span>Welcome to Java Web Example<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">h1<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">p<\/span>&gt;<\/span>This is a simple example of using web.xml and index.jsp to construct a homepage.<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">p<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">body<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">html<\/span>&gt;<\/span>\r\n<\/code><\/pre>\n<p>The index.jsp page in the above example is just a simple demonstration, you can modify and expand it according to your own needs.<\/p>\n<p>Finally, place these two files in the appropriate location of the Java Web application, and then start the server of the application. When users access the root directory of the application, the server will automatically load the index.jsp page as the homepage.<\/p>\n<p>Please make sure that your application is correctly configured and that the server can properly load the web.xml file and index.jsp page.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Creating a homepage in a Java Web application is commonly done by using the web.xml file and index.jsp page.
