Hi there

I had my program working where it would read data from my website (based on one of
your example)


http://MyClubDiary.com/MobileData.aspx


HttpUtils.PostString("Job1", ServerUrl, "Event")

http://myclubdiary.com/MobileData.aspx?query=Event
http://myclubdiary.com/MobileData.aspx?query=Home


I then started getting this error message

java.lang.NullPointerException

The statement

If HttpUtils.IsSuccess(ServerUrl) Then

Is returning false


and cant seem to getting working again



Any ideas?

Thanks

Dave
