How to respond to a simple sort query using JaxRS Rest?

Question

The Dojo Toolkit uses the JsonRest store to communicate to your server with REST calls. In the dGrid the column headers are sortable. When a column is clicked, there is a call to the server with sort details. I do not know how to handle these calls for sorting in my Java code. Using Jax-RS (Jersey 1.13), how do I build a restful method that matches and responds to the sort query string shown below?

For example, sorting by the "ID" column results in this http request:

/rest/Subcategory/?sort(-subcatId)

I am unclear how to extract the sort query string value using this syntax. I tried @QueryParam("sort") and failed. I am currently searching for sort examples in Java. I also am searching the coding conventions for Restful Services.

I was able to solve my problem with this [SO question](http://stackoverflow.com/a/9612720/1653234). — medokr, Dec 20 '13 at 16:15

If your URL is something like :-

/rest/Subcategory/?sort=subCatID

The @QueryParam("sort") should work. I have not worked with Jersey much, but have used this many times in CXF which is also another JAX-RS spec implementation.

The CXF's page http://cxf.apache.org/docs/jax-rs-basics.html explains Jaxrs basics nicely. Hope this helps.

I thought the same. However, Dojo Framework uses the formatting shown above: `?sort(-subcatId)` or `?sort(+subcatId)`. – medokr Dec 20 '13 at 15:46

You can inject the @ServletRequest as a parameter of your resource method, and then retrieve the query string:

@GET
public Response getSubCategory(@Context HttpRequestServlet request) {
    ...
    request.getQueryString();
    ...
}

In order to get Dojo to send it as a query param (i.e. with the sort=+someValue or sort=-someValue make sure you set

"Content-Type":"application/json"
"charset":"UTF-8"

var TrackableRest = declare([Rest, Trackable]);
    var interceptStore = new TrackableRest({
        target: 'rest/intercepts/', 
        accepts: "application/json",
        sortParam: 'sort',         
        rangeStartParam: 'offset',
        rangeCountParam: 'limit',
        headers:{
            'Accept': "application/json",
            'Content-Type':"application/json",
            'charset':"UTF-8"             
        },
        idProperty: 'id'
    });
