Paragraph titled 'public boolean equalsIgnoreCase(String anotherString)';
The example code in the book says

hello.equals("hello"); //Returns true
hello.equals("Hello"); //Returns true

But it should read

hello.equalsIgnoreCase("hello"); //Returns true
hello.equalsIgnoreCase("Hello"); //Returns true

i.e the example is showing the wrong method.

Second full paragraph

In the example code at the top of the page, the property being set is called
"entryTime", however, later in the second full paragraph it is referred to as
"entryDate". Is this a mistake, or am I not reading this section correctly?

Change "entryDate" to "entryTime"

example at the top of the page

In the example at the top of the page, the last XML element, the <security-role> element syntax was incorrect. It
has been changed to use a nested element, like this:

<security-role>
<role-name>admin</role-name>
</security-role>

Note! This has been corrected in the example source
code available for download.

Example 12-10, top of the page

In Example 12-10, top of the page, first <jsp:useBean> element, the element has an empty body so the </jsp:useBean> end-tag
has been removed (line 7 from the top of the example on this
page).

Note! This has been corrected in the example source
code available for download.

second example

The mylib.tld file is described as being installed in the WEB-INF/tlds
directory, but then it's referenced in the sample page like this:

<%@ taglib uri="/WEB-INF/mylib.tld" prefix="test" %>

It should be:

<%@ taglib uri="/WEB-INF/tlds/mylib.tld" prefix="test" %>

For containers that reuse tag handler instances, the per-use state set through nested elements must be reset
before the instance is reused. One way to do this is to
add the following doStartTag() method to the DBTag class:

/**
* Override the default implementation to reset the
* per-use state set by nested elements.
*/
public int doStartTag() {
values = null;
isExceptionThrown = false;
isPartOfTransaction = false;

return EVAL_BODY_TAG;
}

code available for download.

1st paragraph

The description of 'DataSourceWrapper() constructor',
are the same as the description of 'ConnectionPool() constructor'
found at p.485.

Infact, I'm sure they are different.
