WAP Configuration

Hi,

I've set up the apache-tomcat configuration with the aim of having jsp 
pages deliver WML to the WAP browser in the Nokia WAP toolkit.

I have set up a JSP page under Tomcat that just contains WML content.

So far the WAP Toolkit can access the page but as far as I can tell it is 
being encoded in MIME as HTML. At least, the cache for the Nokia Toolkit 
shows an HTML page being cached, though it contains the WML. Also the Nokia 
Browser displays some of the page but it looks like its not displaying 
parts of the page which have '<' or '>' next to them but I'm getting just 
about everything else, including the WML version. I have checked that the 
page is correctly formed by loading it separately as a WML file.

So at the moment my thinking is that Tomcat is handling the JSP but is 
returning the output from the page as HTML, even though the contents are WML.

I have noticed that in my tomcat-apache.conf file that the line that should 
read:

AddType text/jsp .jsp

reads

AddType test/jsp .jsp


I dont know if that is screwing anything up or not.

Can anyone who has done this give me a clue ?

Thanks
Rob

Your Bean should be in a package, and
your <jsp:useBean tag must give the 
complete package in the class= attribute.

Just to save the original poster the trouble of looking it up, the content
type you want is:

text/vnd.wap.wml

First, go directly to the Jakarta web site <http://jakarta.apache.org> and
download Tomcat 3.2.  <Monopoly:metaphor>Do not pass GO.  Do not collect
$200</Monopoly:metaphor>.  Tomcat 3.2 fixes over a hundred bugs in Tomcat 3.1.

Second, the content type that is created by a JSP page is controlled by what your
page declares in the "page" directive, not by Tomcat.  If you wish to have the
output treated as XML, for example, you would include a directive like this at
the top of your pages:

    <%@ page contentType="text/xml" %>

You will need to review the documentation of the WAP Toolkit you are using to
determine what content type it is expecting, but the choice of content type is up
to the page author, not the servlet container.
