Non-Form Based Mapped Properties
Is there a way to use non-form based mapped and indexed properties with
bean and/or html tags? Apparently not?

Thanks, Herbert, let me state more particularly what I am doing. I want to
use Struts tags rather than JSP. I know how to do things in JSP
easily. With the tags, outside of ActionForms, I am confused. In JSP, I
get my results as follows:
<%
Host host = (Host)session.getAttribute(SiteConstant.HOST);
Page key = (Page)host.getPage(SiteConstant.ECLIPSE_BANNER);
%>
<%= key.getValue("bannerLeftBackgroundColor") %>
I want to do with the Struts bean tag what I do now with JSP tags. How do
I do that? This should be simple, but something is not working. I am
either erring with the "define" or the "write" attribute and all the
combinations I try don't work. People have indicated that I need to
retrieve a Map object with getMap(). I don't see why, given what I read in
the literature. If you could help, I would be eternally (or a very long
time) grateful. The classes are given below:
public class Host {
private Map pages;
public Host() {
int size = 89;
this.pages = Collections.synchronizedMap(new HashMap(size));
}
public void setMap(Map pages) {
this.pages = pages;
}
public Map getMap() {
return pages;
}
public void setPage(Object key, Object page) {
pages.put(key,page);
}
public Object getPage(Object key) {
return pages.get(key);
}
} ///;-) Michael McGrady
public class Page {
private Map keys;
public Page() {
int size = 89;
this.keys = Collections.synchronizedMap(new HashMap(size));
}
public void setMap(Map keys) {
this.keys = keys;
}
public Map getMap() {
return keys;
}
public void setValue(Object key, Object value) {
keys.put(key,value);
}
public Object getValue(Object key) {
Object value = keys.get(key);
com.crackwillow.log.StdOut.redirect("log.VALUE: " + value);
if(value == null) {
return "? [" + (String)key + "] ?";
} else {
return value;
}
}
} ///;-) Michael McGrady

Michael,
The tag eventually ends up calling BeanUtils'
PropertyUtils.getNestedProperty(), which has special handling for
collections, including maps. It's actually pretty powerful. It enables
resolving Strings that eventually results in an object or an object's
property. With it, bean:write (or any caller; it's a public method) can
resolve strings like "map1(foo).bar[2].name", with the proper object, of
course. Also, AFAIK, its use isn't tied to ActionForms or DynaBeans.

How can this be, Martin, when the method getMap() has no parameters? What
is the point of the getValue/setValue methods? This is very confusing to
me at this point.

Thanks, Martin. I want to use the getValue method with <bean:write
name="foo" property="value(bar)". I cannot do that? I thought the whole
point was to change the get and set of maps into getValue and setValue so
that we could use reflection. I must be confused, as usual

Re: Non-Form Based Mapped Properties
Posted by Martin Cooper <ma...@apache.org>.
What are you actually trying to do, Michael? Given the code you have below,
and assuming you have a Page instance stored as an attribute named "foo" and
want to print out the value of the "bar" entry in your map, this might be
what you want:
<bean:write name="foo" property="map(bar)"/>
The "map" refers to your getMap/setMap property - you can call it whatever
you want. Your getValue/setValue methods won't be used.

The class is the following, Niall:
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
public class Page {
private Map keys;
public Page() {
int size = 89;
this.keys = Collections.synchronizedMap(new HashMap(size));
}
public void setMap(Map keys) {
this.keys = keys;
}
public Map getMap() {
return keys;
}
public void setValue(Object key, Object value) {
keys.put(key,value);
}
public Object getValue(Object key) {
Object value = keys.get(key);
if(value == null) {
return "? [" + (String)key + "] ?";
} else {
return value;
}
}

I have getMap and setMap. Also, I want to use bean:write rather than
html:text. What do you think?

Re: Non-Form Based Mapped Properties

Haven't done this but either your class needs to be a Map implementation or
you need getter/setter for your Map
public void setMyMap(Map myMap)
public Map getMyMap()
The problem with using the <html> tags and not having your Map as a property
of the ActionForm is that when the form is submitted, Struts is going to try
to populate these properties in the form.

Re: Non-Form Based Mapped Properties

I created a simple class with the map and setValue(Object key, Object
value) as well as getValue(Object key). Then tested the class by putting
an instance of the class into session scope on a page, retrieving the
object on the same page, and trying to access the properties via the mapped
properties value("keyName"). I made sure the object was obtained via the
logic tag, but the mapped property does not work for me. Any ideas? If
not, I will put the whole thing into this exchange.
Thanks.

Yes -- you can used both mapped and indexed properties from normal
JavaBeans. You can be more specific on the problem you are having?
