Re: HttpURLConnection problem

Hi folks,

I am facing very strange problem thats may be concerning to OS. Actually I have piece of code that perfectly working in Windows environment but failed in UNIX.
    When I called the method getContentType(), its returning null in UNIX but retruned "text/comma-separated-values" in windows.
For have a look:-

URL url = URLUtil.makeURL(strUrl);
        HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();
        httpURLConnection.usingProxy();
        httpURLConnection.setRequestMethod("GET");
        httpURLConnection.setAllowUserInteraction(false);
        httpURLConnection.setDoInput(true);
httpURLConnection.setRequestProperty("Content-type","text/comma-separated-values");
        Log.customer.debug("HttpURLConnection" + httpURLConnection);
       Log.customer.debug("HttpURLConnection Content Type" +      httpURLConnection.getContentType());         
        InputStream fromServer = httpURLConnection.getInputStream();
        BufferedReader in = new BufferedReader(new InputStreamReader(fromServer));
        Log.customer.debug("InputStream Return Value" + in);     

Here also I am not able to get any value for getInputStream() method also in UNIX environment.

Please help me, I need it's very soon.
Thanks in advance.

Re: HttpURLConnection problem

It probably has something to do with the difference in Java version installed and
used. Try upgrading it to a newer version or something, maybe they added it only
later.

Re: HttpURLConnection problem

httpURLConnection.setRequestProperty("Content-type","text/comma-separated-values");

Just a pure guess: could it possibly be a case-sensitive/insensitive issue where it
varies by platform?  Because, the true proper HTTP header is "Content-Type", with
capital "C" and "T", both...  Of course, I believe it's either a requirement or at least a
recommendation that you be case-insensitive regarding header fields...  But, maybe
on whatever platform you're on, they don't for some reason... *shrug*

Alternatively, perhaps "text/comma-separated-values" isn't recognized as a valid
content type on one platform, while it is valid on the other...  Not sure if Java cares
about configured MIME types from "/etc/mime.types" or "~/.mime.types" or wherever
your particular Unix system configures such things...  But, perhaps it's something
to consider, anyway...  Try adding "text/comma-separated-values" and see if that
helps...

Re: HttpURLConnection problem

Hi,

Was any solution, found for this. Facing the same issue. Happens for secured protocol (https) URL. The versions of Java on both machines is the same.
