Server returned HTTP response code: 503 on translating even one word

[GoogleCodeExporter]

What steps will reproduce the problem?
1. First would thank you for this library. Have tested translating few 
properties file into different languages. Using the following code:

Translator translate = Translator.getInstance();
String text = "";
try{
 text = translate.translate(str, Language.ENGLISH, Language.CHINESE_SIMPLIFIED);
}catch (Exception e) {
            String message = e.getMessage();
            System.out.println(message);
             }
2. I was able to use it for one day. And it worked perfectly. Later even for 
one small String translation say like "Hello" it started throwing up following 
error
:
java.io.IOException: Server returned HTTP response code: 503 for URL: 
http://ipv4.google.com/sorry/IndexRedirect?continue=http://translate.google.com.
br/translate_a/t%3Fclient%3Dt%26text%3DHello%26hl%3Den%26sl%3Den%26tl%3Den%26mul

    at com.gtranslate.parsing.ParseTextTranslate.parse(ParseTextTranslate.java:19) 

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.
Didnt found any reasons for it. Can someone please explain why is this 
happening. 
Its been 2 weeks since we are not able to translate anything.

I am facing the same problem. There is a similar unofficial API in python 
(goslate), and I read that the Google Translate format changed slightly. They 
have updated the code for it to work. Is it possible to do the same workaround 
for this API? Thanks.

Thanks for your help in stating python API as an alternative. But yes would had 
been better if this existing API could be resolved.

Ok found a solution, sharing with other.
There is a very minor fix required.

STEP1)
In class com.gtranslate.URLCONSTANT
change public static final String GOOGLE_TRANSLATE_TEXT = 
"http://translate.google.com.br/translate_a/t?";

TO 
        public static final String GOOGLE_TRANSLATE_TEXT1 = "http://translate.google.com.br/translate_a/single?";

STEP2) In the class,
the appendURL function needs to be changed as shown
com.gtranslate.parsing.ParseTextTranslate
@Override
    public void appendURL() {
        Text input = textTranslate.getInput();
        Text output = textTranslate.getOutput();
        url = new StringBuilder(URLCONSTANTS.GOOGLE_TRANSLATE_TEXT);
        /* url.append("client=t&text=" + input.getText().replace(" ", "%20"));
        url.append("&hl=" + input.getLanguage());
        url.append("&sl=" + input.getLanguage());
        url.append("&tl=" + output.getLanguage());
        url.append("&multires=1&prev=btn&ssel=0&tsel=0&sc=1");  */

                url = new StringBuilder(URLCONSTANTS.GOOGLE_TRANSLATE_TEXT); 

        url.append("client=t&sl=auto&tl="+ output.getLanguage()
                        +"&hl=" + input.getLanguage()
                        +"&dt=bd&dt=ex&dt=ld&dt=md&dt=qc&dt=rw&dt=rm&dt=ss&dt=t&dt=at&ie=UTF-8&oe=UTF-8&otf=1&rom=1&ssel=0&tsel=3&kc=1&tk=620730|996163"
                        + "&q=" + input.getText().replace(" ", "%20"));

    }
