    <p>Just started to write my JSON webservices for a carpool engine. I am getting a HTTP 404 error as I try to write my registration API's. </p> <p>This is where my problem is</p> <pre><code>"http://localhost:8081/mCruiseOnCarPool4All/carpool4all/Registration" HTTP/1.1 405 Method Not Allowed "http://localhost:8081/mCruiseOnCarPool4All/carpool4all/Registration/Request" HTTP/1.1 500 Internal Server Error "http://localhost:8081/mCruiseOnCarPool4All/Registration/Request" HTTP/1.1 404 Not Found "http://localhost:8081/mCruiseOnCarPool4All/Registration" HTTP/1.1 404 Not Found </code></pre> <p>I know I am missing something really silly here.</p> <p>Web.xml (Jersey Library)</p> <pre><code>&lt;servlet&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;servlet-class&gt;com.sun.jersey.spi.container.servlet.ServletContainer&lt;/servlet-class&gt; &lt;init-param&gt; &lt;param-name&gt;com.sun.jersey.config.property.packages&lt;/param-name&gt; &lt;param-value&gt;com.mcruiseon.carpool4all&lt;/param-value&gt; &lt;/init-param&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;url-pattern&gt;/carpool4all/*&lt;/url-pattern&gt; </code></pre> <p></p> <p>RegistrationService.java, only coded the Post method. I am returning errors on all exceptions and ok with <code>sessionkey</code> when successful. You can ignore the code in the post method, I just wanted to share so that you understand my error handling.</p> <pre><code>package com.mcruiseon.carpool4all; @Path("/Registration") public class RegistrationService { private ClientSession clientSession ; private String sessionKey ; private SessionManager sessionManager ; @Context UriInfo uriInfo; @Context Request request; @POST @Path ("Request") @Consumes({ MediaType.APPLICATION_JSON }) public Response post(JAXBElement&lt;AMessageStrategy&gt; element) { try { clientSession = new ClientSession(God.mCruiseOnServer) ; } catch (InvalidServerDNSorIPException e) { e.printStackTrace(); return Response.serverError().build() ; } sessionKey = sessionManager.setClientSession(clientSession) ; clientSession.setSessionKey(sessionKey) ; clientSession.getSendQueue().sendRequest(element.getValue()) ; try { clientSession.waitAndGetResponse(element.getValue()) ; } catch (WaitedLongEnoughException e) { return Response.serverError().build() ; } catch (UnableToResolveResponseException e) { return Response.serverError().build() ; } return Response.ok(sessionKey).build(); } } </code></pre> <p>Junit test case (removed all the HttpConnection code)</p> <pre><code>ClientIdentityConcrete clientIdentity = new ClientIdentityConcrete("username", "password", "secretkey") ; RegistrationRequest register = new RegistrationRequest(clientIdentity); String jsonStr = mapper.writeValueAsString(clientIdentity); HttpPost request = new HttpPost("http://localhost:8081/mCruiseOnCarPool4All/Registration/Request"); </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
