Consuming Liferay JSON Web Services

In previous post, we exposed custom liferay plugin service as JSON web service. In this post, we are consuming that service using sample standalone java class.

	public class JsonTest {
	public static void main(String[] args) throws Exception {
	HttpHost targetHost = new HttpHost("localhost", 8080, "http");
	DefaultHttpClient httpclient = new DefaultHttpClient();
	httpclient.getCredentialsProvider().setCredentials(
	new AuthScope(targetHost.getHostName(), targetHost.getPort()),
	new UsernamePasswordCredentials("username", "password"));
	AuthCache authCache = new BasicAuthCache();
	BasicScheme basicAuth = new BasicScheme();
	authCache.put(targetHost, basicAuth);
	BasicHttpContext ctx = new BasicHttpContext();
	ctx.setAttribute(ClientContext.AUTH_CACHE, authCache);
	HttpPost post = new HttpPost("/<<portlet-context>>/api/secure/jsonws/sample/say-hello");
	List<NameValuePair> params = new ArrayList<NameValuePair>();
	params.add(new BasicNameValuePair("name", “Harish”));
	UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params, "UTF-8");
	post.setEntity(entity);
	HttpResponse resp = httpclient.execute(targetHost, post, ctx);
	resp.getEntity().writeTo(System.out);
	httpclient.getConnectionManager().shutdown();
	}
	}
