I modified Example03.java to call https://localhost:9443/ccm/rpt/repository/workitem?fields=workitem/workItem/id API like below. I hope this might help you. Cheers.

public static void main(String[] args) {

//============== Code to adapt to your own configuration =============//

String server = "https://localhost:9443/ccm"; // Set the Public URI of your RTC server

String login = "clmadmin"; // Set the user login 

String password = "clmadmin"; // Set the associated password

//============== -------------------------------------- =============//

String reportAPI = server + "/rpt/repository/workitem?fields=workitem/workItem/id";

// Setup the HttClient

HttpClient httpclient = new DefaultHttpClient();

HttpUtils.setupLazySSLSupport(httpclient);

// Setup the rootServices request

HttpGet reportDoc = new HttpGet(reportAPI);

reportDoc.addHeader("Accept", "application/rdf+xml");

try {

// Request the Root Services document

HttpResponse reportResponse = HttpUtils.sendGetForSecureDocument(

server, reportDoc, login, password, httpclient);

HttpUtils.printResponseBody(reportResponse);

reportResponse.getEntity().consumeContent();
