Shekar,
If you use the html-el taglib, your html:checkbox value can be
"${userObj.propertyName}" where "propertyName" is whatever property you
need from your user object.
With the non-EL HTML taglib, you would need to set the property value in
the page scope with something like this before the html:checkbox tag:
Then the value attribute of the checkbox tag should just be
"checkboxVal".
I'm not sure how the properties with underscores translate into EL
expressions.
And it may take some tweaking; I'm writing this out off the top of my
head. But I felt that even that was better than allowing you to go
forward with Java scriptlets.

Red Phoenix,
No, I don't think the serialVersionUID is necessary for Struts, but it
is good practice to give your Serializable classes some value for it.
Check out the Javadocs for the Serializable interface -- it's a standard
Java interface.
Probably that number was generated by calculating a hash value from the
object's fields. I seem to remember reading something about some IDEs
producing that value for you. You can maintain it yourself as well.

Rick, If you perform a redirect instead of a forward from the action, the new page will have a new form, because the data will not carry over (because you are using request scope). As a bonus, if the user reloads the page, they will not be resubmitting the form post that adds an employee. Chris -- Christopher D.

Right. While it is possible to do this, it does make it difficult to
read the code. Better to use two different variable names. Then you
never have to worry about which variable you're actually using, or
mistakenly use the instance variable because you *thought* the local one
was still in scope, when it was not.
Actually the one exception I employ is with setter methods:
public void setFoo( Object foo ) {
this.foo = foo;
}

Robin,
See Ed Griebel's most recent reply regarding the use of the "${var}" EL
in your JSP.
And go back to using the link tag for your CSS. The script tag is not
going to work.

Ilja,
Tere!
This is the expected behavior. I'm not sure what version of Struts
you're using, but you can check out the source for the (1.x)
tag here:
http://svn.apache.org/viewvc/struts/struts1/trunk/taglib/src/main/java/org/apache/struts/taglib/bean/WriteTag.java?view=markup
The relevant part is from lines 330 to 348 (indenting modified):
if (formatString != null) {
try {
format = NumberFormat.getNumberInstance(locale);
if (formatStrFromResources) {
((DecimalFormat) format).applyLocalizedPattern(
formatString);
} else {
((DecimalFormat) format).applyPattern(formatString);
}
} catch (IllegalArgumentException e) {
JspException ex =
new JspException(messages.getMessage(
"write.format", formatString));
TagUtils.getInstance().saveException(pageContext, ex);
throw ex;
}
}
There seems to be some discussion of this in the Struts JIRA system:
http://issues.apache.org/struts/browse/STR-1865?page=all
See Ted Husted's comments. Of course, he's talking about the date (not
number) formatting, but it only serves to highlight the distinction
between the handling of the two types. Note that if you look at the
code immediately following what is quoted here, you'll see that the
SimpleDateFormat constructor is *always* passed the locale.
I found all this stuff by Googling various combinations of "WriteTag",
".applyLocalizedPattern", and "IllegalArgumentException"
Hea õnn!

The fact that the path, type, and forward values are similar is simply a convention that makes it easier to understand without memorizing the struts-config file. The /editRegistration.do URL is mapped to the EditRegistrationAction class in the tag shown. It's tied to the form-bean above through the name attribute of the tag. The Action forwards to the JSP view via a call at the end of its execute method: return mapping.findForward( "success" ); And as you see there is a local forward for this action keyed on "success" to "/registration.jsp". If it was absent, there would need to be a global forward for it. I hope this helps.
