Application of JSP Technology in WAP

The basic principles of JSP technology's Application in WAP:

1. WML labels and statements can be directly written in JSPProgram.

2. If you want to use JSP to process WML labels and statements, you need to use "<%" and "%>". The format is:

<%

... (WML statement line compiled by JSP );

%>

For example, the following statements use JSP's out. println to output WML labels and statements:

<%

Out. println ("<p> ");

Out. println ("hello from script code! ");

Out. println ("</P> ");

%>

3. The WML file type can be declared using the JSP response object, or the page language can be declared in one piece. Their formats are as follows:

<% Response. setcontenttype ("text/vnd. WAP. WML"); %>

Or <% @ page Language = "Java" contenttype = "text/vnd. WAP. WML" %>
