6th paragraph

When referring to the environment variables to set (JAVA_HOME and PATH), JAVA_HOME is
split across two lines. For the sake of clarity, this token should not be split.

Third paragraph under "installing the book examples" heading

The stated location of the book examples on the author's website is incorrect.

He notes that they can be located at:

http://www.thejspbook.com/examples/jspbook.zip

and they're actually at:

http://www.thejspbook.com/jspbook.zip

This used to be the case but I've added a link so both URLs work now

Source code

The name of instance variable fileNames, which has been written as
plural, should be replaced by fileName in the following places:
[...]

The code is correct; I use plural because it's a list of filenames, and
the code compiles and runs as-is.

The code listed in "Brief Custom Action Introduction for Java Programmers" contains

the following function:

public int doEndTag( ) {
mmb.setCategory(category);
JspWriter out = pageContext.getOut( ).
try {
out.println(mmb.getMessage( ));
}
catch (IOException e) {}
return EVAL_PAGE;
}

The second statement ends with a period rather than a semicolon.
Should be:
public int doEndTag( ) {
mmb.setCategory(category);
JspWriter out = pageContext.getOut( );
try {
out.println(mmb.getMessage( ));
}
catch (IOException e) {}
return EVAL_PAGE;
}

3rd paragraph

The sentence "For instance, February 28 is a valid date only for a
leap year". In our calendar, there is a February 28 every year. I
suppose the author meant the February 29.

Ooops, yes that's my mistake.

For the "dataSource" attribute, the corresponding Java type "javax.sql.DataSource"
has the last "e" character formatted as the "or" that follows it, while it should
have the same formatting as "javax.sql.DataSourc" that it belongs to. (in other words, the "e" shouldn't be bold)

Index entres for Delimiters (under Symbols heading)

There are several errors with the entries for the various delimiters:
1. The directive delimiter <%@ only has page 48 listed, but it is also discussed in
detail on page 28.
2. The entry for <%= is identified as a comment delimiter when it is in fact an
Expression Delimiter.
3. The comment delimiter <%-- is missing from the Symbols entry.

So this:
<%@ ... %>, directive delimiter, 48
<%= ... %>, comment delimiter, 29
should be:
<%@ ... %>, directive delimiter, 28, 48
<%= ... %>, expression delimiter, 29
<%-- ... --%>, comment delimiter, 48
