Serving WAP Documents

Configuration
It is quite easy to enable a Virtual Server web server to serve WAP (Wireless Application Protocol) documents. Your Apache Web Server simply needs the correct MIME Types.

1. Connect to your Virtual Server via Telnet or SSH and use an online editor, like pico, to open your web server configuration file (~/www/conf/httpd.conf). Or, download your web server configuration file via FTP, making sure to download (and upload) in ASCII format. Then make the following additions to the httpd.conf file.

   
   AddType text/vnd.wap.wml               .wml
   AddType image/vnd.wap.wbmp             .wbmp
   AddType application/vnd.wap.wmlc       .wmlc
   AddType text/vnd.wap.wmlscript         .wmls
   AddType application/vnd.wap.wmlscriptc .wmlsc
   

2. You might also want to add index.wml to the DirectoryIndex directive, like this:

   
   DirectoryIndex index.wml index.html
   

Testing
Create a ~/www/htdocs/hello.wml test file to verify that you've configured settings properly. The following sample code show how to create two sample cards using Wireless Markup Language (.wml).

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="My Wap Page"> 
<p>Hello world - this is my first wap card!</p> 
<p><a href="#card2">Go to the second card</a></p> 
</card> 
<card id="card2" title="Second Card"> 
<p>This is my second wap card!</p> 
<p><a href="#card1">Go back to the first card</a></p> 
</card> 
</WML>

When you develop WML pages, you should always check the page in one of the available Software Development Kits (SDKs):

• Nokia WAP Developer Tools
• Ericsson Developers Zone
• Phone.com UP.SDK

In order to view your new WAP document, you will need a WAP-enabled cell phone or a WAP emulator. There are many WAP emulators available, including these:

• Wapalizer - WAP Browser
• WapTiger - Java WML-to-HTML converter
