The following three MIME types can be used for XHTML MP documents:<\/FONT><\/P> application\/vnd.wap.xhtml+xml<\/FONT><\/P> application\/xhtml+xml<\/FONT><\/P> text\/html<\/FONT><\/P><\/LI><\/OL> The MIME type specified by the Open Mobile Alliance [OMA]<\/A> for XHTML MP documents is “application\/vnd.wap.xhtml+xml”. This MIME type is required for some WAP browsers (for example, some Nokia Series 60 browsers) to display XHTML MP documents correctly.<\/FONT><\/P> Another choice is the “application\/xhtml+xml” MIME type. It is the MIME type for XHTML Family document types.<\/FONT><\/P> The “text\/html” MIME type is also a possible choice. It is the MIME type of HTML documents. Using “text\/html” for XHTML MP documents has the benefit that your XHTML MP pages will be viewable on ordinary web browsers without any problems. (Some web browsers like IE 6 do not show documents with MIME types “application\/vnd.wap.xhtml+xml” or “application\/xhtml+xml” but will bring up a dialog box to let you open the file in an external program or choose a location to save the file.) The drawback is that the user agent will not treat your XHTML MP pages as XML documents, which means the user agent may not complain even if the markup code does not follow strictly the XML rules.<\/FONT><\/P> Another option is to detect the MIME types that can be handled by a user agent and choose the MIME type dynamically. For example, if your server finds out that a certain user agent can handle the “application\/vnd.wap.xhtml+xml” MIME type, then all your XHTML MP documents will be delivered as “application\/vnd.wap.xhtml+xml” to this user agent.<\/FONT><\/P> To choose the MIME type dynamically, you need to write a few lines of code using a server-side scripting language (e.g. ASP, JSP, Perl, PHP). The pseudo-code is shown below:<\/FONT><\/P> Obtain the accept header value of the HTTP request received. The accept header contains all MIME types that can be handled by the client user agent that sends the request.<\/FONT><\/P> If the accept header value contains “application\/vnd.wap.xhtml+xml”, set the MIME type of the XHTML MP document to “application\/vnd.wap.xhtml+xml”. The following example demonstrates how to use JSP to write the code. If you use a server-side technology other than JSP, the code will be slightly different but the idea is the same.<\/FONT><\/P> <% Here are some descriptions of the above JSP code:<\/FONT><\/P> 1. The accept header value is obtained from the HTTP request. It is then stored in the variable acceptHeader<\/I>.<\/FONT><\/P> String acceptHeader = request.getHeader(“accept”);<\/FONT><\/P> 2. After that, the variable acceptHeader<\/I> is checked to see if it contains the words “application\/vnd.wap.xhtml+xml” or “application\/xhtml+xml”. The indexOf(String str)<\/I> method of the String object returns the index of the first occurrence of the str<\/I> substring. If str<\/I> is not found, -1 is returned by the indexOf(String str)<\/I> method. In other words, if str<\/I> is found, the return value will not be -1.<\/FONT><\/P> if (acceptHeader.indexOf(“application\/vnd.wap.xhtml+xml”) != -1) 3. The method<\/FONT><\/P> response.setContentType(…);<\/FONT><\/P> is used to set the MIME type of a document.<\/FONT><\/P> The following example illustrates how to use the JSP code in an actual XHTML MP document. What you need to do is very simple — Just copy and paste the JSP code into the XHTML MP document and use “.jsp” as the file extension. (The XHTML MP markup in this example will be discussed in detail in the following sections.)<\/FONT><\/P> <\/P> <?xml version=”1.0″?> <html xmlns=”<\/FONT>http:\/\/www.w3.org\/1999\/xhtml<\/FONT><\/A>“> <body> if (acceptHeader.indexOf(“application\/vnd.wap.xhtml+xml”) != -1) File Extension<\/STRONG><\/FONT><\/FONT><\/P> The file extensions of static XHTML MP documents are “.xhtml”, “.html” and “.htm” typically. You can use other file extensions you like, as long as the MIME type associated with the file extension is set correctly at your WAP server’s configuration file. If you are going to use a server-side technology such as ASP, JSP, Perl, PHP or SSI (Server Side Includes) to add content to XHTML MP documents dynamically, you may need to change the file extension of your XHTML MP documents to that used by the server-side technology. For example, the typical file extension used by PHP is “.php”, while that used by SSI is “.shtml”.<\/FONT><\/P><\/FONT><\/DIV><\/p>\n","protected":false},"excerpt":{"rendered":" MIME Types The following three MIME types can be used for XHTML MP documents: application\/vnd.wap.xhtml+xml application\/xhtml+xml text\/html The MIME type specified by the Open Mobile Alliance [OMA] for XHTML MP documents is “application\/vnd.wap.xhtml+xml”.
