REST service not working after simple change

Question

I follow this guide to learn some REST services and AJAX calls: http://www.mkyong.com/webservices/jax-rs/integrate-jackson-with-resteasy/

I changed this endpoint:

@GET @Path("/get") @Produces("application/json") public Product getProductInJSON() { Product product = new Product(); product.setName("iPad 3"); product.setQty(999); return product; } 

To return the product in jsonp format:

 @GET @Path("/get?callback={name}") @Produces("application/javascript") public String getProductInJSON(@PathParam("name") String callback){ Product product = new Product(); product.setName("iPad 3"); product.setQty(999); String productString = callback + "({" + product.toString() + "})"; return productString; } 

with toString () of the product:

 @Override public String toString() { return "name:" + name + "," + "qty:" + qty; } 

But now, when I check that the URI works in the browser, with:

http: // localhost: 8080 / restws / json / product / get? callback = process

I have this error message:

HTTP ERROR: 404

Could not find resource for relative: / json / product / get full path: http: // localhost: 8080 / restws / json / product / get? Callback = process

RequestURI = / restws / JSON / product / we receive

Can someone help me understand why he gave me this error after this minor change? Thanks

The request parameter is not part of @Path. You must handle them with @QueryParam , as shown in the Jersey User Guide .
