Errata

The sentence that is in error says: "So far, JavaMail Transport objects are only exceptions I�ve encountered." This should be "So far, JavaMail Transport objects are [the] only exceptions I�ve encountered."

Note from the Author or Editor:
p. 31 change " are only exceptions" to " are the only exceptions"

Chapter 4: Internet Addresses Section: The InetAddress Class Sub-section: Lookups by IP address The following sentence has the error: "A DNS lookup for the actual hostname is only performed when the hostname is requested, either explicitly via a getHostName()." Words have been dropped from the sentence, and the "either" should be qualified by a subsequent pair of options, or removed altogether.

Note from the Author or Editor:
change "either explicitly via a getHostName()" to "either explicitly via getHostName() or implicitly by toString()"

Chapter 5: URLs and URIs Section: The URI Class Sub-section: Resolving Relative URIs The error is very minor; instead of "three" in the next line, it should be "two" For example, take these three statements: URI top = new URI("javafaq/books/"); URI resolved = top.resolve("jnp3/examples/07/index.html"); It should look like this: For example, take these [two] statements: URI top = new URI("javafaq/books/"); URI resolved = top.resolve("jnp3/examples/07/index.html");

Note from the Author or Editor:
Change "For example, take these three statements:" to "For example, take these two statements:" on p. 148

Note: since I am reading the online book, I ascribe a page number of 9999. The error is in Chapter 1 of Safari Books Online, under the section entitled "The Internet", in the paragraph whose heading is "Internet Address Blocks". The sentence with the problem is this one: "However, the lowest address in all block used to identify the network itself, and the largest address is a broadcast address for the network, so you have two fewer available addresses than you might first expect." ... the error is in the first clause of the sentence - it makes no sense as written.

Note from the Author or Editor:
Change "However, the lowest address in all block used to identify the network itself, and the largest address is a broadcast address for the network," to "However, the lowest address in a block is used to identify the network itself, and the largest address in a block is a broadcast address for the network,"

First page of Chapter 3: Threads The sentence at fault is: "Given the high performance of threads in modern virtual machines and operating systems, as well as the relative simplicity of a building a thread-based server, a thread-based design is usually where you should start until you can prove you�re hitting a wall." The corrected sentence should remove the [a] below: "Given the high performance of threads in modern virtual machines and operating systems, as well as the relative simplicity of [a] building a thread-based server, a thread-based design is usually where you should start until you can prove you�re hitting a wall."

Note from the Author or Editor:
Correct. Change "of a building a thread-based server" to "of building a thread-based server"

Chapter 3. Threads Synchronization section The problem is with the following sentence: "In order for this to work, you must henceforth use only the view returned by Collections.synchronizedSet/List/Map." This should be: "In order for this to work, you must [subsequently] use only the view returned by Collections.synchronizedSet/List/Map." ***** It is not my intention to make suggestions regarding the bulk of the writing style in any textbook, as style is so subjective. However, "henceforth" means "from this time forward", whereas "subsequently" means "the time after a given event as occurred...", and so has the correct meaning. "henceforth" is simply incorrect.

Note from the Author or Editor:
Picky, but OK. Just delete the word "henceforth" on p. 76. It's pretentious anyway.

Chapter 5: URLs and URIs Section: The URL Class Sub-section: public final Object getContent() throws IOException The text following the Example 5-3 says the following: % java ContentGetter http://www.oreilly.com/ I got a sun.net.www.protocol.http.HttpURLConnection$HttpInputStream</programlisting> and this should be % java ContentGetter http://www.oreilly.com/ I got a sun.net.www.protocol.http.HttpURLConnection$HttpInputStream</programlisting>

Note from the Author or Editor:
Yes, and ick. On p. 134 in the first two code fragments can you check the DocBook markup? Something's gone wonky here in the middle of the page. If necessary I can check the files in Atlas, though it may take me a little while. Let me know if you want me to do that. However the problem may come in the conversion from asciidoc to DocBook later in the process.

Chapter 5: URLs and URIs Section: Communicating with Server-Side Programs Through GET Sub-section: N/A In the code for Example 5-10, the following works, but does not agree with the way the dmoz site itself is set up to work: URL u = new URL("http://www.dmoz.org/search/q?" + query) This results in URLs like: http://www.dmoz.org/search/q?q=java Instead, I would expect the following: URL u = new URL("http://www.dmoz.org/search?" + query) so that the code would generate URLs like this: http://www.dmoz.org/search?q=java

Note from the Author or Editor:
This is correct. Change URL u = new URL("http://www.dmoz.org/search/q?" + query) to URL u = new URL("http://www.dmoz.org/search/?" + query) as suggested
