I have programmed a midlet to send information via a servlet. However I get the following error java.lang.IllegalArgumentException: Space character in URL.
I understand that the error says what it means and that there must be a space in the URL. However I have looked at the URL but see no spaces. Could this error be refering to something else I include my midlet and servlet code below. I have been looking at this for quite a while but cannot see what is wrong. I hope somebody can help.
