I have the following code:
logic:iterate id=users name=userInfo
bean:write name=users property=userName/ /logic:iterate
How can i get the first record ?
JSTL makes this easy:
c:out value=${userInfo[0].userName} /
Or, to write out only the first one while iterating the loop:
I think life would be easier if you store your Category_VO objects in a
java.util.Collection, then use JSTL forEach tag. Something like this:
%
Collection v = new Vector();
v.add( new Category_VO(cat 1) ); //Assuming your constructor takes a
String which is the shortTitle
//psuedo code.
List categoryList = Category.getList();
request.setAttribute(categories, categoryList.toArray());
logic:iterate id=category name=categories
/logic:iterate
I made the first bit up. But should give you the idea.
jsp:useBean id=categories
%
LabelValueBean[] lvArray = new LabelValueBean[] {
new LabelValueBean(label1, value1),
new LabelValueBean(label2, value2),
new LabelValueBean(label3, value3),
new LabelValueBean(label4, value4) };
request.setAttribute(lvArray, lvArray);
%
logic:iterate

The property attribute of the tag should point to a boolean property of
the FormBean. If that property is true the box will be checked.
...unless you're using an old(er) version of the checkbox tag... I know in
the older (1.0x) versions this was rather broken (i.e. only a string of 'T'
or 'F' or

Non-String Form bean properties are evil though, you'll thank yourself later
if you use Strings

Non-String
Sorry for emailing so many questions. My last one (i promise) is,
how do I set an html:checkbox to display as checked?

Non-String Form bean properties are evil though, you'll thank yourself later if you
use Strings. As long as the String is set to something sensible like true or
false, your checkbox will be properly set.
I'm sure there are ample posts on the pros cons of this approach, here's one pro
Boolean form properties are cool too (at least in my experience)...

Do you have a valid action element in your struts-config.xml file
specifying the editRecord.do action (assuming you're using extension
mapping)?

What do you mean by inside a jar file that is referenced in the
classpath explicitly? Aren't you putting your application classes in
the WEB-INF/classes or WEB-INF/lib directory? You will always get
into trouble if you try to externally control the CLASSPATH.

The jar file, called iNDemandCH.jar lives in this directory.
C:\Tomcat\webapps\indemand\WEB-INF\lib
the weird thing about this is that some .do actions work, and others don't. Do you
think it might be that it can't see the class files?
