Good afternoon,
I'm using JAVA and JSP to program. I have a JSP variable and I need to pass the stored value to the JAVA code.
I need to pass the variable "X" that is in index.jsp to variable "Y" which is in the main of indexJava.java
Can someone help me?
Depends on how you are going from JSP to Java.
If it is a simple function call between <%% > or $ {}, is a normal parameter pass.
If it's a forward, use the request scope.
If it is a redirect , use the session scope.
If you give more details on how your code is structured, I can improve this response.
public class ServletDemo extends HttpServlet{
private String y;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
y = request.getParameter("x");
}
}
HTML
<!DOCTYPE html>
<html >
<head>
<title>Test</title>
</head>
<body>
X : <input type="text" value="" id="x" />
</body>
</html>
