With this example we are going to demonstrate how to get Request Parameters in a JSP page. JavaServer Pages (JSP) is a server-side programming technology that enables the creation of dynamic, platform-independent method for building Web-based applications. JSP have access to the entire family of Java APIs, including the JDBC API to access enterprise databases. In short, to get Request Parameters in a JSP page you should:
- Create a jsp page that begins with the
<%code fragment%>scriptlet. It can contain any number of JAVA language statements, variable or method declarations, or expressions that are valid in the page scripting language. - Use the
getParameter(String name)API method ofjavax.servlet.http.HttpServletRequestobject to get the value of a request parameter as a String.
Let’s take a look at the code snippet that follows:
GetRequestParameter.jsp
<html>
<head>
<title>Java Code Geeks Snippets - Get Request Parameter in JSP Page</title>
</head>
<body>
Parameter myparam: <%= request.getParameter("myparam") %>
</body>
URL:
http://localhost:8080/jcgsnippets/GetRequestParameter.jsp?myparam=myvalue
Output:
Parameter myparam: myvalue
This was an example of how to get Request Parameters in a JSP page.
