NoSuchMethodError error when invoking projectListRequest.execute() method - google-bigquery

Question

I am trying to develop a simple BigQuery App using JSP Servlets. I am following the exampla given on https://developers.google.com/bigquery/docs/authorization
In the early stages, the doGet method was not getting invoked and so I overrided the Service method. The code looks like this
public class BigQueryWebServerAuthDemo extends AbstractAuthorizationCodeServlet {
protected void service(HttpServletRequest req, HttpServletResponse resp)
throws IOException, ServletException {
System.out.println(" Start service ");
doGet(req, resp);
}
#Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException {
System.out.println(" Start doGet ");
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException {
System.out.println(" Start doPost ");
response.setContentType("text/html");
PrintWriter writer = response.getWriter();
System.out.println(" Begin loadbigquery() ");
Bigquery bigquery = CredentialUtils.loadbigquery();
System.out.println(" end loadbigquery() ");
Bigquery.Projects.List projectListRequest = bigquery.projects().list();
ProjectList projectList = projectListRequest.execute();
if (projectList.getProjects() != null) {
java.util.List<Projects> projects = projectList.getProjects();
writer.println("<h3>BigQuery project list:</h3>");
for (ProjectList.Projects project : projects) {
writer.printf("%s<br />", project.getProjectReference().getProjectId());
}
}
System.out.println(" End doPost ");
}
#Override
protected AuthorizationCodeFlow initializeFlow() throws ServletException, IOException {
System.out.println(" inside BigQueryWebServerAuthDemo --- initializeFlow() ");
return CredentialUtils.newFlow();
}
#Override
protected String getRedirectUri(HttpServletRequest request) throws ServletException, IOException {
System.out.println(" inside BigQueryWebServerAuthDemo --- getRedirectUri() ");
return CredentialUtils.getRedirectUri(request);
}
#Override
protected String getUserId(HttpServletRequest request) throws ServletException, IOException {
System.out.println(" inside BigQueryWebServerAuthDemo --- getUserId ");
return request.getParameter("userId");
}
}
I have a JSP page from where I am getting the parameter "userId". Now I get a
NoSuchMethodError on execute() method [projectListRequest.execute()] though Eclipse compiler doesnt show any error.
Below is my web.xml config info
<servlet>
<servlet-name>oauth2callback</servlet-name>
<servlet-class>main.BigQueryWebServerAuthCallBack</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>oauth2callback</servlet-name>
<url-pattern>/oauth2callback</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>ServletBigQuery</servlet-name>
<servlet-class>main.BigQueryWebServerAuthDemo</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServletBigQuery</servlet-name>
<url-pattern>/ServletBigQuery</url-pattern>
</servlet-mapping>
I have 2 more classes CredentialUtils and BigQueryWebServerAuthCallBack as given in the tutorial mentioned above.
I am actually new to Java . I want get rid of the NoSuchMethodError error. Any help will be greatly appreciated.
