First error your code gave was FileNot found in the line
BufferedReader br=new BufferedReader(new FileReader(D:\writer.txt"));
I hope you have the file in your local machine.
Next the file needs to have some data to translate.
Last error I got was connection refused. Which will be solved by adding the following code at the start of your "go" method.
System.setProperty("http.proxyHost", "proxy.****.com");
System.setProperty("http.proxyPort", "####");
Authenticator authenticator = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return (new PasswordAuthentication("user",
"PASSWORD".toCharArray()));
}
};
Authenticator.setDefault(authenticator);
Now, you tell us, what error you got?
