I'm using google-speller-api.jar it throws exception
org.xeustechnologies.googleapi.spelling.SpellCheckException: java.io.FileNotFoundException: https://www.google.com/tbproxy/spell?lang=en&hl=en
Here is my code
SpellChecker spellChecker=new SpellChecker();
spellChecker.setLanguage(Language.ENGLISH);
SpellRequest spellRequest=new SpellRequest();
spellChecker.setOverHttps(true);
spellRequest.setText("aple");
SpellResponse spellResponse=spellChecker.check(spellRequest);
Google discontinued this service thats why you are getting 404 error since that service is not available.
