How to retrieve all project areas from a Java Team Server?

I installed a local Java Team Server, version 3.0.1. I'm trying to use the REST web services to retrieve all the project areas. For that I first authenticated myself:

public HttpContext login() throws ClientProtocolException, IOException {

        client = new DefaultHttpClient();
        CookieStore cookieStore = new BasicCookieStore();
        HttpContext localContext = new BasicHttpContext();

        localContext.setAttribute(ClientContext.开发者_如何学CCOOKIE_STORE, cookieStore);

        HttpGet httpGetID = new HttpGet("https://localhost:9443/ccm/authenticated/identity");
        client.execute(httpGetID, localContext);
        httpGetID.abort();

        List<Cookie> cookies1 = cookieStore.getCookies();
        for (Cookie cookie : cookies1) {
            System.out.println("\t"+cookie.getName()+" : "+cookie.getValue());
        }

        List<NameValuePair> authFormParams = new ArrayList<NameValuePair>();
        authFormParams.add(new BasicNameValuePair("j_username", "ADMIN"));
        authFormParams.add(new BasicNameValuePair("j_password", "ADMIN"));

        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(authFormParams, "UTF-8");
        HttpPost httpPostAuth = new HttpPost("https://localhost:9443/ccm/authenticated/j_security_check");
        httpPostAuth.addHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
        httpPostAuth.setEntity(entity);
        client.execute(httpPostAuth, localContext);
        //httpPostAuth.abort();

        List<Cookie> cookies2 = cookieStore.getCookies();
        for (Cookie cookie : cookies2) {
            System.out.println("\t"+cookie.getName()+" : "+cookie.getValue());
        }

        return localContext;
    }

Then I try to get the project areas with the following code:

HttpGet getProjectsRequest = new HttpGet("https://localhost:9443/ccm/oslc-scm/catalog");
        getProjectsRequest.addHeader("Content-Type", "application/xml;charset=UTF-8");
        getProjectsRequest.addHeader("Accept-Charset", "UTF-8");
        getProjectsRequest.addHeader("Accept", "application/x-oslc-cm-change-request+xml");

        ResponseHandler<String> handler = new BasicResponseHandler();
        String projectResponse = client.execute(getProjectsRequest, handler, localContext);
        System.out.println(projectResponse);

Unfortunately, the answer is always the same:

{
    "userId": "ADMIN",
    "roles": [
        "JazzUsers",
        "JazzProjectAdmins",
        "JazzAdmins"]
}

This looks for me like a JSON object. Instead I should get a XML document, that lists all projects. I already tried the same REST service with a REST plugin for Firefox. There I get the XML document as expected. However, I can't see any differences between my code and the things I do in the plugin.

You can find the answer here.

Here is what I understood: basically, you need to visit another page to receive a cookie and then run your query. Just run the same execute twice and you see what I mean.

You can get All Project Areas of a particular user using DraftTeamProcessRestAPIs

and in particular see this section

This API responses in XML

and also there are ReportableRestAPIs which can fulfill what you want using this URL in the code:

 https://<server>:<port>/ccm/rpt/repository/foundation?fields=foundation/projectArea/(name|teamMembers/userId)
