each time when I click submit button in xhtml document, the nokia 5110 simulator will display the file format unknow. even I use the sample code about submit a form it still have the same problem. I can use normal link to display A.xhtml. but I can not use <form action="A.xhtml">(just for testing), it will appear file format unknow. Actually, I have already set the IIS the mime type for that: application/vnd.wap.xhtml+xml. by the way, I use the same document try the <form><action ="A.xhtml>, it works well in firefox brower.
Anybody knows the problem?
