1. Can I embed WMLScript in the WML web page? Not. Unlike the JavaScript embedded HTML web page, WMLScript must be included in a separate file for WML calls.
2. Can you see the source code for the WML page? If you have a SDK, you may see that the WML code is just like browsing the web in the browser. If you have only one HTML webmap, you can visit http://www.webcab.de/ to see the WML code.
3. Can I create a web using Active Server Pages (ASP)? Yes, you can create WML like a creation of HTML. If you have written the ASP page for the creation of WML, just remember that you can use the following settings when setting the MIME type: response.contenttype = "text / vnd.wap.wml"
4, can you use cookies in WAP? In theory, it is possible. But not all WAP phones support this feature. However, you can program, leave a hidden space to store some information ID. (If the POST method is used in the information head or use a GET method in the URL)
5. Can you create a WML web page using Java Servlets? Yes, everything is as in HTML, but remember that the MIME type must be set correctly: response.setContentType ("text / vnd.wap.wml");
6, what is the WAP gateway? The WAP gateway is a software entity in the mobile network. It is connected to the Internet or the company's Internet is responsible for content and applications to transfer to the WAP phone. Some WAP gateways are also responsible for the conversion of HTML to WML.
7, do I need a WAP gateway? No, no need. If you want to be a WAP information provider, you can use the existing web server (just change the MIME type). The phone is connected to your server through the WAP network of the local mobile network. However, if you have a WAP gateway will be more convenient. Because it is part of the mobile network, you can use the information like mobile users!
8, where can I find a WAP gateway? Nokia has produced a free WAP gateway and server, specific information. You can refer to http://www.nokia.com/corporate/wap
9. How do I translate HTML's webpage to WML? Before considering transforming HTML, you should take into account that WML is designed for small screen, it is not as visual and rich as HTML. Any conversion may affect the content or format of the HMTL, like script. Some simple HTML web pages can be more converted. The conversion can be performed at some browser, or on the filter system of the WAP gateway.
10. How to build a WBMP picture? Some plugins like Adobe Photoshop 5.x and PaintShop Pro are support for WBMP format. There are also Gingco and Teraflops to provide development tools for multi-formatted images in WBMP format.
11. How do I build a WML page that can access the database? This problem is not different from the establishment of an HTML page. Any technique for server-side can be used to create a dynamically accessible WML page. Examples of this: Active Server Pages (on IIS servers), CGI and Java servlets.
12. How do I create a WML page in GoldFusion? When designing in GoldFusion, you generally need to add:
(Of course, you have to guarantee your web content compatible with WML V1.1.)
13, WAP and Bluetooth technology, what is the competition between Windows CE? Nothing at all! WAP is an agreement that allows information in the form of web to send to mobile devices (such as mobile phones). EPOC and Windows CE are an operating system that provides browsers that browse WML web pages. Bluetooth technology is RF (Radio frequency) technology for short-range wireless networks. 14. What is the security of WAP? There is a layer called WTLS in WAP, providing encryption and verification for server-client security, which prevents malicious access, providing solutions for e-commerce and enterprise network applications.
15. Can you let the WAP device dial by WML? WAP phones may use the WTAI (wireless telephone application interface) to achieve, for example: WMLScript: wtapublic.makecall ("9287787"); but the first generation WAP device does not support this feature!
17. Can we facilitate the management of the content on the WML page? Currently don't work. But Oracle is developing a database-driven document server, called: Panama, is said to manage the information on the WAP phone very well.
18. What is WAP to transfer on the GSM phone? On the GSM phone, WAP can pass the short message service (SMS) or via CSD. The latter provides greater bandwidth.
19. What format is transmitted on a WAP phone? WAP standard indicates the format of the picture is WBMP. To understand more detailed information on this format, you can refer to http://www1.wapforum.org/tech/terms.asp?doc=spec-waespec-19990524.pdf
20, can WAP run on GPRS? Yes, GPRS is a new mobile transport service that sends the packet to the mobile device. Its WAP transmission is faster than using GSM through SMS and CSD technology.
21. How much KB can be displayed on the WML web page to display on the phone? This is different depending on the phone. But as an incumbent, it is best to guarantee your WML web page 1400bytes.
22. What operating system should I use at the WAP client? As long as there is a microwser containing a WML, what operating system can be. Representative OS is Windowsce, EPOC, Palmos.
23, how do I write and test my WML page? There are many such SDKs now. Nokia and Ericsson's SDK use very widely. If you just write a general WML web page, any such editor is a good choice, of course, this area is also available, you can go to http://www.allaire.com/ to see.
24. What types of mobile networks can WAP run? WAP is designed for the widest mobile network, which is GSM, PDC, CDPD, CDMA, TDMA, PHS, DECT, as well as the third-standard standard. Many programmers are discussing Wireless technology, that is, often said WAP. But what WAP is? What does he represent? Why is such a weird name? We will answer these questions! First, let's take a look at its background information.
Where did all these WAP discussions come? Currently, users who use mobile phones in the world are constantly increasing. Mobile phone users around the world are more than users of desktop PCs. In a global scale, 380 million mobile phone users are now 380 million mobile phones. By 2003, users of mobile phones will reach 1 billion, which is 1/6 of the Earth population. The mobile phone has a huge user foundation, and the development of mobile phones has also provided a huge exchange communication platform, and this platform is mature every day. Now let's imagine a new technology - it allows all mobile phone users to access the Internet. A mobile Internet, along with its growth, M-Commerce mode will be thrown behind. Now, this mobile Internet already exists. This new technology makes the wireless device access to the Internet. This technology is WAP. Accurately, what WAP is "something"? WAP is Wireless Application Protocol (wireless application protocol), which is said that WAP is a possible technique that enables wireless devices to become possible, which converts information on the Internet into information displayed on your mobile phone screen and other mobile devices. How does the mobile phone access to the Internet? Think about how the Internet is usually working. Simply put, the Internet is implemented using two computers: servers and clients. The server is stored in the server, and the client is our PC or is the computer we browse to the web. WAP technology work is a bit similar. Different is that we use mobile phones to access the Internet instead of PC to access the Internet, the mobile phone is our client. This is a bit too simplified. In order to access the mobile network to the Internet, it is necessary to have a WAP gateway, and the mobile phone we use as a client must support WAP, and the website must also provide a web page in WAP format. What is a WAP gateway? A WAP gateway is a middleware located on the Internet and mobile network. When we send a request to the Internet, it translates our "WAP" request to "Web" request. Correspondingly, when receiving the response of the Internet, the WAP gateway also converts the "Web" request from the Internet to "WAP" request. "The website must also provide a web page for WAP format"? Today's web page is written in HTML, but it is too complicated to the mobile phone, and the speed is slow. The web page that the mobile phone can access is written in WML (Wireless Markup Language). WML significantly simplifies the number of downloads and expressions, so we say that "Website must provide WAP format" means that the source HTML language of existing websites must be converted to WML. About WML WML is a quite concise design language, which has no excessive functionality, and is also very new (first release in 1999). WML allows programmers to specify the layout and appearance of the text, the level, links of the page. In the hierarchy, these web pages are called "decks"; separate web pages are called "cards". WML generates a static page. The static page only displays text, allowing users to jump from one page to another link page. So is interesting as a moving web page! Is it saying that the static page is the only web page that can be displayed in the mobile phone? No, the truth is not this! WML has its own JavaScript version called WML Script. WML Script allows programmers to create additional functions for WML web pages. The current WML file and WML script file must also be saved independently, so there is a large string file to associate a WAP format page. Have you changed the existing website into a WAP format? In fact, there are many such conversion software in the market.
