    text
    copied!<p>Is there a way to use this parameter style:</p> <blockquote> <p>/products/123;456;789</p> </blockquote> <p>in JAX-RS with Jersey? If I use PathParam, only the first parameter in the list is returned. I tried to escape the semicolon but then Jersey returns only "123;456;789" as the value of the first parameter list entry</p> <p>I declared the GET method as</p> <pre><code>public List&lt;Product&gt; getClichedMessage(@PathParam("ids") List&lt;String&gt; idList) </code></pre> <p>Update: I am referring to the <a href="http://jersey.java.net/nonav/documentation/1.1.5/user-guide.html#d4e226" rel="noreferrer">Jersey user guide</a> for Jersey 1.1.5:</p> <blockquote> <p>In general the Java type of the method parameter may (...) 4) be List, Set or SortedSet, where T satisfies 2 or 3 above. The resulting collection is read-only. (...) Sometimes parameters may contain more than one value for the same name. If this is the case then types in 4) may be used to obtain all values.</p> </blockquote> <p>Update: here is my test code:</p> <pre><code>package de.betabeans.resources; import java.util.List; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; @Path("/test") public class TestResource { @GET @Path("/{ids}") @Produces({"text/plain"}) public String getClichedMessage(@PathParam("ids") List&lt;String&gt; idList) { return "size=" + idList.size(); } } </code></pre> <p>Test URL with semicolon escaped: <a href="http://localhost:8080/resources/test/1%3B2%3B3" rel="noreferrer">http://localhost:8080/resources/test/1%3B2%3B3</a></p> <p>Update: the <a href="http://java.net/projects/jersey/sources/svn/content/tags/jersey-1.3/jersey/changes.txt" rel="noreferrer">changelog for Jersey 1.3</a> include this information:</p> <blockquote> <p>Fixed issue 540<br> <a href="http://java.net/jira/browse/JERSEY-540" rel="noreferrer">http://java.net/jira/browse/JERSEY-540</a> Parameterized types of List/Set/SortedSet are supported for parameters, for example @QueryParam("d") List>, if there is a StringReaderProvider registered that supports the type List.</p> </blockquote> <p>I'll check out StringReaderProvider based on this post <a href="http://comments.gmane.org/gmane.comp.java.jersey.user/7545" rel="noreferrer">http://comments.gmane.org/gmane.comp.java.jersey.user/7545</a></p>
