[ERROR] Unable to instantiate 'com.example.booksearch.server.SearchServiceImpl'
java.lang.ClassNotFoundException: com.example.booksearch.server.SearchServiceImpl

From Log you will see the following:

com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException
   Serialization status
      Instantiable
   Path
      'com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException' is reachable as a subtype of type 'class com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException'
      Started from 'com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException'

also has some issues with the following code snippet which I infact replaced:

private Document getBookListXMLDocument(String searchTerm)
throws IOException, ParserConfigurationException, SAXException {
String url = SEARCH_SITE_URL_BASE + searchTerm;

HttpClient client = new HttpClient();
GetMethod get = new GetMethod(url);

-------------------------------

The program encounters exception as soon as GetMethod is invoked. Instead I used:

HttpURLConnection urlConnection = (HttpURLConnection) (new URL(url)
.openConnection());
InputStream in = urlConnection.getInputStream();
DocumentBuilder builder = builderFactory.newDocumentBuilder();
return builder.parse(in);
