Re: java class cast exception accessing wml page


(do you really want to output .wml instead of html ?)

anyway, when I look at your file, I get something like this :


< postfield name="firstName" value="$(firstName)" />


 what is in the value="" attribute is not computed. Is this normal ?

Re: java class cast exception accessing wml page

Is your web service configured to serve WML pages?  Are the appropriate MIME types being sent?


I was able to reprouce the issue with the URL you posted, but the page works fine when hosted from my local web server.
