Hello,
I was trying out "The Multi-Device Challenge" example in the PortletHowTo
section of the Jetspeed documentation and ran into a few errors.
On testing with Openwave 5.0, I got the following error when I tried to
login to the portal as user "turbine":
Translation failed for content-type: text/vnd.wap.wml
With the Nokia WAP Simulator, the error was:
Content could not be encoded by the gateway
Has anyone run into this problem or better still, solved it? Looking forward
to your replies. I am including the code I wrote and also the deployment
descriptor for this portlet.
Thanks,
Vipul.
