jClip should be iClip. The URL has also changed (though the original works): http://www.irradiatedsoftware.com/iclip/

wget command contains extraneous characters,a~@~S in several places.

Note from the Author or Editor:
The command at the bottom of the page reads:
wget --mirror ?~@~Sw 2 --html-extension ?~@~S-convert-links
?~@~SP c:\wget_files\example1

It should be:

wget --mirror --w 2 --html-extension --convert-links -P c:\wget_files\example1

Second section of example code.

In the following snippet of code the class keyword is missing.

public PersonDemo() {
Job job = new Job("Safety Engineer", 50000.00);
Person homer = new Person("Homer", job);
homer.changeJobPositionTo("Janitor");
}

It should be:

public class PersonDemo() {
Job job = new Job("Safety Engineer", 50000.00);
Person homer = new Person("Homer", job);
homer.changeJobPositionTo("Janitor");
}

Note from the Author or Editor:
The errata lists the correct change: the word "class" should be inserted between "public" and "PersonDemo".

4th paragraph

When discussing the problem of the Collection.remove() method, the code example uses a 0:

list.remove(0);

But the description talks about removing 2.

Note from the Author or Editor:
On page 139, the sentences:
In this case, Java autoboxes the integer 2 into an Integer object, looks in the list to see if there is an element with the content of 2, fails to find one, and doesn?t remove anything from the list.

The two "2" characters should change to "0" (zero, not O).

"For Windows, Command Prompt Explorer bar is a great open source utility..."

The said utility does not work on Windows Vista. Also, on the following page: "In both Windows and Mac OS X, you can drag a directory into a command-line view to copy the path". That technique also does not work in Vista.

Also, all of the powertoys mentioned in that chapter are not supported (or installable) on Vista.

Note from the Author or Editor:
The references to "Windows" in this entire section should exclude Windows Vista.

... the pipe command (the / character).

the slash glyph (/) is used instead of the pipe (|). Oops.

Note from the Author or Editor:
This needs to be fixed. The sentence on page 194 (mid-page) that starts "The concept worth noticing here is the pipe command (the | character)." should have a "|" character, not a "/" character. Interestingly, when I past it from the PDF, the character pastes correctly, but it's clearly a forward slash in the text.

End of Section

It's section 4.3, right at the end you give the URL for cURL at http://www.curl.org...which is not the correct URL. That's some web designers home page. The ACTUAL site is: http://curl.haxx.se/

I'm reading it online on Safari, so I don't know the page number, or if this error also appears in the print edition. My subscription is through school, and the 'print friendly view' is not enabled for this title, so I can't see if it is repeated there, or just an error in the html version.

Note from the Author or Editor:
The URL should be changed to http://curl.haxx.se/.
