The error is because '' does not extend from '', as the error message is implying.

Do you need to call any methods of ''? If not just cast the connection as '' instead (as that IS a superclass) and you should be right!

I tried this

Intead of  this : URL url = new URL(fURL);

i tried with this : wsURL = new URL(null, fURL,new;

and now i am getting this  error : No X509TrustManager implementation available

Please help me

Did you try what I mentioned above?

For that second error message, did you get that at the ... new URL(...) line or does it throw that error later when you are actually trying to use the connection?

Thanks it is working perfectly  with these two combination : url = new URL(null, fURL,new;  connection = (HttpsURLConnection) url.openConnection();

Hi, i am facing some other problem, it is working when i just pass "",  but when i pass the query parameters like below it is not working, tried with encoding the URL and got "MalformedURLException" exception, if i try without encodeingURL it just trys for long time and gives connection timeout error, i am not sure but thinking it may be because of SSL cetificate, if it is SSL related could you please let me know the steps to add the SSL in my server. jNRdDhYImgco

mccarlIT Business Systems Analyst / Software DeveloperCommented:
I would doubt that it is SSL related because as far as I know the certificate applies to the site as a whole, so if it works without the query parameters, I don't think that would be it.

Is this a site that you normally have to login to access these pages? Maybe that SessionGUID is no longer valid by the time you are trying to access it.

Actually, looking it again, you say that this is your server? You should be able to debug on the server side why the connection times out?
quickjavaAuthor Commented:
Thanks for your reply, tried checking it in the log but is not showing any error except timeout.
i am also thinking the same, the SessionID is getting invalide when i connect to the server,  i am not hunderstanding how to maintain valid sessionID.

if there is anyway of maintaining the valid sessionID please let me know.

I asked this previously....

> Is this a site that you normally have to login to access these pages?

If so, then you may have to get your code to follow the same login procedure in order to get a valid SessionID.
