Do you have an example of the error message your script generates?

The servlet is telling me that it's recieving a get request. What can you tell my from your side? I tried the script twice to make sure I was getting the same response.

It's still giving me a get response. I think the problem may be with Internet Explorer itself. My post's work fine when I post from a jsp page to the servlet but when I use internet explorer it sends me a get response. The guys on the java.sun.com forums said that netscape doesn't produce this same behavior. Do you have any knowledge of this happening?

I fixed it finally. I was using a url that redirects to my original url and that was generating a get request. Wow, that was some ordeal.

Could you give that test script again with the reciever email as JJC_Industries@hotmail.com? I want to test it as it'll work.

[br]I'm using this code that I basically cut and pasted from your code samples and I keep getting an invalid response from the server. Any ideas?
