Chapter 8 - Building and Invoking Requests

The following code will give a compiler error because of the "accept()" method. The method "request()" is missing. It should precede "accept()". Customer customer = client.target("http://commerce.com/customers/123") .accept("application/json") .get(Customer.class); List<Customer> customer = client.target("http://commerce.com/customers") .accept("application/xml") .get(new GenericType<List<Customer>>() {});

The third sentence states: "You also saw how we used the @Path annotation to bind a URI pattern to a Java method." I believe it should state: "You also saw how we used the @Path annotation to bind a URI pattern to a Java class." This is the code segment that it refers to. @Path("/customers") public interface CustomerResource {

In the example source code for ex04_3 The CustomerResource class has the added constructors that would be needed if not doing fully dynamic dispatching. The CustomerDatabaseResource class in the example also does not have the locateCustomerResource(String db) method, which I believe would have used the added CustomerResource constructor that accepts a Map<Integer, Customer>

An example that starts at the bottom of p 112 and continues onto p. 113 1) creates a VariantBuilder, 2) adds MediaTypes, 3) adds languages, 4) adds encodings 5) does a vb.build() This will generate an empty List of Variants. I examined the source code (for Jersey 1.3 implementation at least) and it is clear from that that you need to introduce an add() sa all build does is return any variants that were add via the overloaded add methods. Put another way, the add methods are the ONLY methods that actually generate variants and adds them to the internal list. Thus just invoke build w/o an add, will generate an empty list.

Starting on page 111, there are a series of examples that invoke a single-argument constructor for MediaType. I have checked the documentation for both JAX-RS 1.0 and 1.1 and in both cases it seems pretty clear that there are no single argument constructors.

The link element in the HTTP response message provides a URI whose implied ID (133) conflicts with the id attribute of the order element (233) and the implied ID in the Location header (233).

@DELETE was not explained until page 43. But in page 43 1st paragraph. It is mentioned that we have covered @DELETE has been covered before page 43. It could be that @DELETE needs to be explained before page 43 or the mention in page 43 may be corrected. This is not a serious problem, still I felt that it can be corrected.

Second example

The second example is supposed to apply to application servers that are not JAX-RS aware. In dropping this into a Tomcat6 server with jsr311-api-1.1.jar, the com.jaxrs.vendor.JaxrsVendorServlet is reported as not found. I can't find any mention of this class in the book or any reference to it on the web except in pages that reference this book. Some explanation of what this class is and how to obtain it would be immensely helpful.

In the paragraph about GZIP compression, the author refers to chapter 10. However in chapter 10 (Scaling JAX-RS Applications) there is nothing mentioned about compression. Is this piece missing from chapter 10, or is it just a mistake to refer to chapter 10?

At the top of the Regular Expressions section, the regular expression for only decimals was given as: @Path("{id : \\d+}") But I think just \d+ is correct (the double-backslash ends meaning a literal backslash, not what is wanted here.)

"In Apache HttpClient 4.x, the org. apache.http.client.DefaultHttpClient class is responsible for managing HTTP connections."

change "throw new RuntimeExceptioin" to "throw new RuntimeException" Also I think that this listing needs more imports e.g. class HttpGet requires: import org.apache.http.client.methods.HttpGet; and DefaultHttpClient requires: import org.apache.http.impl.client.DefaultHttpClient; Also there is something wrong with this code: InputStreamReader(response.getEntity().getInputStream())); I think there should be: InputStreamReader(response.getEntity().getContent())); Javadoc tells me that there is no getInputStream() method for HttpEntity interface, and correct method is getContent(). It was tested on HttpClient 4.0 and 4.0.1 (from http://archive.apache.org/dist/httpcomponents/httpclient/binary/httpcomponents-client-4.0-bin-with-dependencies.tar.gz) with Oracle JDK6. Finally my imports looks: import java.io.*; import org.apache.http.*; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; Regards, Greg

There are some errors. The Expires header value is GMT, so it should set TimeZone for Calendar's factory method. And Calendar#set doesn't return Date instance.

The text says that "If your application server is JAX-RS-aware or, in other words, is tightly integrated with JAX-RS, we can declare our ShoppingApplication class as a servlet". I'm using Glasfish V3, which is a JAX-RS-aware application server, but the Application subclass was not recognized as a servlet. Instead, it produces the error below: java.lang.ClassCastException: com.restfully.shop.services.ShoppingApplication cannot be cast to javax.servlet.Servlet I believe this is a particularity of each application server and cannot be generalized.

I found the discussion of the "purge" operation interesting, yet I felt that there were other, less "forced" ways of doing the same thing. For instance, rather than creating a "purge" operation why not get all cancelled orders... GET /orders?cancelled=true HTTP/1.1 ...and iterate through them calling DELETE on each one. DELETE /orders/x HTTP/1.1 Even better why not just delete only canceled orders like so: DELETE /orders?cancelled=true HTTP/1.1 Granted that looks a lot like your "overloading DELETE" example, but it's different in one important way. It does not really overload the DELETE operation, but rather filters the resources that are being deleted. I would really like to hear your thoughts on this if you have time. Thanks, Tony Childs

1st paragraph - updateCustomer() method

The update of user "current" properties is non-atomic. This can lead to user "current" to contain data from two request (if the requests are parallel and a context switch occurs after the first request has copied some but not all of the properties). I would use customerDB.put(update.getId(), update) instead of copy each property.
