3rd paragraph

The second section of the first sentence of the indicated paragraph (as set off by a semicolon) reads: "Tim Berglund, principle software developer and owner of the August Technology Group, LLC;" That should say "... principal software developer ..." [principle -> principal]. Unfortunately, this is a common misunderstanding, even among experienced writers. The word "principal" means "First, highest, or foremost in importance, rank, worth, or degree; chief." (from The Free Dictionary). It can be either a noun or an adjective (here, it is an adjective) while "principle" can only be a noun. See the usage note for "principal" on The Free Dictionary's site for more details.

4th paragraph

In the bullet list in paragraph 3, the class MessageConsumer is listed, but in paragraph 4, the statement is made as follows: "Once you have a Session, you can create a Message, MessageProducer, and MessageReceiver." I think "MessageConsumer" was intended.

Note from the Author or Editor:
You are correct - On page 12, MessageReceiver should be changed to MessageConsumer.

3rd paragraph, 2nd sentence

The sentence reads, "Although full-blown SOA implementations are continuing to evolve, many companies are tuning to messaging solutions as a step toward SOA. When I first read it I thought "tuning" should be "turning". I guess it could be tuning, but turning sounds more appropriate to me. Is it correct as written?

Note from the Author or Editor:
Yes, 'tuning' should be 'turning'. Thank you for identifying this typo.

Second indented command section

I'm going through chapter 2 of the JMS book, 2e, page 29, and there is a command: java ch02.chat.Chat TopicCF topic1 Fred The java source file for class Chat is in [book base dir]\examples\JMS_2ed_non_spring\jms_2ed_non_spring\src\main\java\ch02. "ch02" is the package that contains Chat. I'm not that great with packages, so it might be my lack of understanding, but where/how does the the component "chat" come into play in the package specification "ch02.chat.Chat" of the class? There is no corresponding subdirectory "chat" to which it would correspond, and the package name as specified in the source is "ch02". Is this a typo? Am I missing a point, or shoud the command read as follows? java ch02.Chat TopicCF topic1 Fred Or should "chat" be part of the package name in the code? Thanks.

Note from the Author or Editor:
You are correct - the text indicates the wrong package - the code for the chat is located in the package "ch02, NOT "ch02.chat". Thanks for catching the error!

Figure 3-1

Item "JMSCorrelationID" is listed twice

Note from the Author or Editor:
There are two forms of the JMSCorrelationID - one that returns a byte array, and one that returns a String. That is why both are listed. However, it still is only one header property, so indeed the second one should be removed.

1st non-code paragraph

In the following sentence: "When a Java primitive is written to the BytesMessage using one of the set<TYPE>() methods, the primitive value is converted to its byte representation and appended to the stream." "set<TYPE>()" should be replaced by "write<TYPE>()".

Table 4-1

Point-to-point API "QueueSender" and "QueueReceiver" swapped respect to General API "MessageConsumer" and "MessageProducer"

Note from the Author or Editor:
Correct; page 66, Table 4-1, "QueueSender" should be aligned with "MessageProducer", and and "QueueReceiver" should be aligned with "MessageConsumer"

Code listing beginning with "Message rmsg = ..."

The line 'throw new IllegalStateException("Invalid message type);' is missing a double quote before the end parenthesis.

Note from the Author or Editor:
There is a double-quote missing in the String text - it should read throw new IllegalStateException("Invalid message type");

Replace "Nondurable" with "Durable" inside upper boxes

Note from the Author or Editor:
Correct; igure 5-4 refers to durable subscribers, not non-durable subscribers. Boxes at top should say "Durable".

1st paragrapg code snippet createDurableSubscriber

public TopicSubscriber createDurableSubscriber(Queue queue, String name, String messageSelector, boolean noLocal) should be ... public TopicSubscriber createDurableSubscriber(Topic topic, String name, String messageSelector, boolean noLocal)

Note from the Author or Editor:
Good catch - this is correct - the Queue should be replaced with Topic.

Hello, In page 217 in the Memory leaks section's second paragraph, we can read this line : Although Java has built-in memory management through garbage collection, it is an oversimplification to think that garbage collection permanently solves the problem of memory links. IMHO, it should read : ... solves the problem of memory leaks. So use the word leaks instead of the printed word links . HTH, David

Note from the Author or Editor:
Yes, the work links should be leaks.
