Body
i agree with you about alternative solutions which you mentioned above <pre><code>1. Use POST instead of GET; 2. Transform the List into a JSON string and pass it to the service. </code></pre> and its true that you can't add <code>List</code> to <code>MultiValuedMap</code> because of its impl class <code>MultivaluedMapImpl</code> have capability to accept String Key and String Value. which is shown in following figure <img src="https://i.stack.imgur.com/kDwdG.png" alt="enter image description here"> still you want to do that things than try following code. Controller Class <pre><code>package net.yogesh.test; import java.util.List; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; import com.google.gson.Gson; @Path("test") public class TestController { @Path("testMethod") @GET @Produces("application/text") public String save( @QueryParam("list") List<String> list) { return new Gson().toJson(list) ; } } </code></pre> Cleint Class <pre><code>package net.yogesh.test; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import javax.ws.rs.core.MultivaluedMap; import com.sun.jersey.api.client.ClientResponse; import com.sun.jersey.api.client.WebResource; import com.sun.jersey.api.client.config.ClientConfig; import com.sun.jersey.api.client.config.DefaultClientConfig; import com.sun.jersey.core.util.MultivaluedMapImpl; public class Client { public static void main(String[] args) { String op = doGet("http://localhost:8080/JerseyTest/rest/test/testMethod"); System.out.println(op); } private static String doGet(String url){ List<String> list = new ArrayList<String>(); list = Arrays.asList(new String[]{"string1,string2,string3"}); MultivaluedMap<String, String> params = new MultivaluedMapImpl(); String lst = (list.toString()).substring(1, list.toString().length()-1); params.add("list", lst); ClientConfig config = new DefaultClientConfig(); com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config); WebResource resource = client.resource(url); ClientResponse response = resource.queryParams(params).type("application/x-www-form-urlencoded").get(ClientResponse.class); String en = response.getEntity(String.class); return en; } } </code></pre> hope this'll help you.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
