However, if you know how to make it work with any of them, maybe I did something wrong and could use the help to make it work.</p> <p>Otherwise, does anyone know of a good option?</p> <p>Thanks in advance.</p> <p>--- EDIT --- @pace</p> <p>Here's what I tried using JAX-RS but I <strong>can't receive</strong> a <strong>JSON object</strong> from a <strong>POST</strong> method with it.</p> <pre><code> @Path("/getUserByName") @POST @Consumes("application/json") @Produces("application/json") public Person getUserByName(@PathParam("name")String name, @PathParam("lastname")String lastname) { return new Person(name, 23, lastname); } </code></pre> <p>I'm calling the WS with HTTPRequest but that doesn't allow me to send a JSON object.

    1. COJAX-RS should be able to do that. What problem exactly did you run into?

    3. COWhen you say you're calling the web service with HTTPRequest do you mean your client library doesn't support JSON? Are you trying to call into another web service? Also, your method should be taking in a Person object if you want to receive JSON. As it stands your method is getting the firstname and lastname from the path but your path doesn't seem setup to provide firstname/lastname. Have you setup the POJOMappingFeature in your web.xml as described in http://jersey.java.net/nonav/documentation/latest/user-guide.html#json

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.

SQuiL has stopped working due to an internal error.

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