static on String months first line

I have tried out the month example (3.3 pp.58-61). I am not a seasoned jsp
developer so this could easily be my misunderstanding.

When using the EL
{calendar.monthSet.months[9]} (9 is an example)...it won't find the property if it's
static, as it is in the text of the book (assuming it's strictly looking for a
javabean property). It worked by making months non static.

Also I believe:
{calendar.monthSet.month[monthIndex]}
should read:
{calendar.monthSet.months[monthIndex]}

Also, how can monthIndex be a bean, if it's an integer? (p.60)

public void reset(){...}

The reset should reinitialise the web link list..otherwise you get an index out of
bounds if you resubmit the form AND exception and the reset button fails to work.

<html-el:text property='color[${ctr}]'/>
ctr is not defined in the loop as before.

To fix this, you'd need:
<html-el:text property='color[${loopStatus.index}]'/>

start of 2nd paragraph

The 2nd paragraph states that an Action is included. It's only included with the
source as ProcessDateAction.java, and it's incorrectly included in the ch04 folder
instead of Ch03.

4th paragraph

It says:

Then, the rowSet property is used to access a List of DynaBeans.

But the code in Example 10-3 says:
<logic:iterate id="row" name="rowSet" propert="rows">

I looked at http://commons.apache.org/beanutils/api/org/apache/commons/beanutils/RowSetDynaClass.html and the property is called rows.
