JSPs and HTML files in Google AppEngine

Posted on Posted in Development

Further from my previous post, you can add JSPs and HTML files to the project, simply by placing them under the src/main/webapp directory.

So for a JSP, you want something like src/main/webapp/index.jsp:-

<html>
<head>
<head><title>Hello from DevSoup</title></head>
</head>
<body>
<p><a href="http://www.devsoup.co.uk">DevSoup</a>'s JSP says hello @ <%= new java.util.Date().toString() %>.</p>
</body>
</html>

Or you can put anything in src/main/webapp/index.html:-

<html>
<head>
<head><title>Hello from DevSoup</title></head>
</head>
<body>
<p>Welcome! This is a static HTML file. For dynamic usage, try one of the following:-</p>
<ul>
    <li><a href="servlet/">Servlet</a></li>
    <li><a href="index.jsp">JSP</a></li>
</ul>
</body>
</html>

I also changed the deployment descriptor in src/main/webapp/WEB-INF/web.xml so requests under the servlet directory are handled by my servlet, and the other files are handled by the default servlet.:-

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
    <servlet>
        <servlet-name>devsoup-gae_helloworld</servlet-name>
        <servlet-class>uk.co.devsoup.gae.helloworld.Main</servlet-class>
    </servlet>
 
    <servlet-mapping>
        <servlet-name>devsoup-gae_helloworld</servlet-name>
        <url-pattern>/servlet/*</url-pattern>
    </servlet-mapping>
</web-app>

<servlet-mapping>
<servlet-name>devsoup-gae_helloworld</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
</web-app>

You can then deploy this and it should work.
