Server returned HTTP response code: 400

I'm trying to access a URL in my program. I opened the URL page in my web browser and it looks fine but when I run my program. I got an IOException that says: "Server returned HTTP response code: 400"

I'm not sure why I got this since it seems that I could open it in my web browser (Internet Explorer).

This is what I do in my code:
BufferedReader reader = new BufferedReader(new InputStreamReader(new URL("http://myPage.htm").openStream()));

Any advise?

Thanks

Hi astorer,

Thanks for your reply. I used http://mypage.html just as an example.
I have found the solution that the URL actually have spaces which automatically converted to %20 by the browser but not by the java program.

I have requested this question to be removed.

Hi rnicholus!
use URLEncoder.encode to encode a URL same as:
public static String forURL(String aURLFragment){
String result = null;
try {
result = URLEncoder.encode(aURLFragment, "UTF-8");
}
catch (UnsupportedEncodingException ex){
throw new RuntimeException("UTF-8 not supported", ex);
}
return result;
}

Dear moderator: I have provided the solution that I found for this problem in my post on 07/11/2006 05:40PM CDT.

I'm not sure how the system works here.

People have been trying to help with solutions to the problem. The reason that experts could not find the actual problems was that the question was not posed correctly.

Specifically, the URL quoted was "http://myPage.htm". This is clearly a bad URL and would have caused the problem defined. In effect, I answered the question posed. To refuse the points because the question was badly posed seems a little uncharitable and against the spirit of what Experts Exchange is all about.

Dear astorer:
I think you're right that I should have made the questions more clear at the very beginning, i.e: mentioning that the URL quoted was just an example.
I'm sorry.

Thanks for all the help

Awwwww, thanks. I feel bad now!
