This page details the steps necessary to create a REST client, using eclipse, that is able to communicate with the holiday web service.  For the client I used [Jersey|http://jersey.java.net/], and downloaded the client and core jars [here|http://jersey.java.net/nonav/documentation/latest/chapter_deps.html#core_client].

*1.  Create a new project using eclipse*

*2.  Add the Jersey jars to the buildpath.*

*3.  Go to run configurations and add the Jersey jars to the classpath*


NOTE: When creating a client for the test server it is required that you add the test site's certificate to the keystore as described [here|http://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed.html],
            and then run the project with arguments (In Eclipse these should be added to the VM arguments of your project's run
            configuration):

                            \-Djavax.net.ssl.trustStore=/path/to/keystore
                            \-Djavax.net.ssl.trustStorePassword=changeit (default password is changeit)

*4.  Create the main method*

import javax.ws.rs.core.MultivaluedMap;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.core.util.MultivaluedMapImpl;

public class holidayClientMain {

  public static void main(String\[\] args) \{
    try \{
      Client client = Client.create();
      WebResource webResource = client.resource("https://www.test.hawaii.edu/its/ws/holiday/rest/closest");
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MultivaluedMap<String, String> parameters = new MultivaluedMapImpl();

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parameters.add("date", "2012-01-01");
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parameters.add("isObserved", "true");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ClientResponse response = webResource.queryParams(parameters).accept("application.json").get(ClientResponse.class);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (response.getStatus() \!= 200) \{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\}

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;String output = response.getEntity(String.class);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println("Output from Server .... \n");
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(output);
&nbsp;&nbsp;&nbsp;&nbsp;\}
&nbsp;&nbsp;&nbsp;&nbsp;catch (Exception e) \{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.printStackTrace();
&nbsp;&nbsp;&nbsp;&nbsp;\}
&nbsp;&nbsp;\}
\}
