Re: Using Bean Tag inside html Tag. Urgent

2003-06-09 Thread Zhu He 
Does that mean bean:define id=styleClassStr name=loginAF
property=useStyleClass type=java.lang.String/
is equivalent of
% String styleClassStr = loginAF.getUseStyleClass(); %
or
% String styleClassStr =
request.getAttribute(loginAF).getUseStyleClass();
//with proper casting.
%

One thing confuses me is a bean used by struts tag sometimes is obj stored
in request/session, sometimes is variable that can be used by jsp scriplet.
If someone could please clearify this for a newbie, I'd really appreciate
it.

thx
Zhu He

 One option:

 bean:define id=styleClassStr name=loginAF property=useStyleClass
 type=java.lang.String/
 html:text property=userName styleClass=%= styleClassStr %/

 You can't nest tags as properties in other tags.

 Hi,
 
  I am facing problem in using bean:write / tag inside html:text
 /.
  What I am trying to do is something like this
  html:text property=userName styleClass=bean:write
 name=\loginAF\
 property=\useStyleClass\ /  /
  I am not getting the output I am expecting. I expect to get the
 value
 stored in useStyleClass in styleClass attribute but What I am
 getting in
 styleClass is the entire tag i.e. bean:write tag.
  Any solutions for this problem.

b)  plus the addressbar doesn't change.
this sometimes causes problem, for example starting from a fowarded page,
you go to another webpage, then go back you will not get the same page.

 1) You need to set your forward redirect=(true|false) in your
 struts-config.xml for that particular action mapping.
 2) The difference...
 a) redirect generates a whole new request by sending a header back to
the
 client you lose all of your request scope data.
 b) forward continues with the same request and arrives at the view with
 request object intact.

 RequestDispatcher vs response.redirect();

 This is probably a silly question, but what's the difference between
 forward and redirect?

Re: newbiew Q: how to do redirect instead of forward

2003-06-06 Thread Zhu He 

 Ok.  So, from the user's perspective, when we do a redirect, they are sent
 to a different location.  When we do a forward, they are not, even if the
 content changes?
The content changes to the content of the new page, but address bar stays
the same because all the forwarding is done on the server side.

 I tried this and it also didn't work.  The get and set methods do not
 call the HashMap directly, cause a HashMap uses get and put.

 The geters and setters that I supply are the interface to the HashMap,

 is a set of strings?  Is this correct, or am i confused?

Re: Action Form: HashMap

2003-06-06 Thread Zhu He 
Yes the name is important, but I have to change my previous statements a
little.

Using the one from online doc
public FooForm extends ActionForm {

private final Map values = new HashMap();

public void setValue(String key, Object value) {
values.put(key, value);
}

public Object getValue(String key) {
return values.get(key);
}

}
html:text property=value(foo)/The key of name matching is
property=value(foo) will trigger invocation of setValue(foo, )  and
getValue(foo)The name matching pattern is property=xxx(key) matches
function setXxx() getXxx()
The example you give is ActionForm to change java beans.
But set/get values from type Map doesn't fit into the bean coding
convention. That's where map backed ActionForm come into play in struts1.1

 Thanks for your response.  It still doesn't work.  I looked at the page
 you refered me to and the HashMap is names values and the getter/setter's
 are named getValue, and setValue.  Is the s at the end of the map name
 important.

 I changed my form/jsp to work with an element of a known name.

 in the form
 private String foo = null;

 public String getFoo ( ) {
 return foo;
 }

 public void setFoo ( String foo ) {
 this.foo = foo;
 }

 and the input tag becomes

 html-el:text property='${element.element}'
   value='${element.value}'/

 And it works like a champ.  Is there anything else I have to do
 to make the HashMap work?  Like use a different Base Form class?

 This seems easy enough?  I'm losing my mind!

tags to compare properties of 2 bean.

2003-06-05 Thread Zhu He 
Hi
We can use struts tag to compare the property of a bean to a value, like
logic:equal name=bean property=prop1
 scope=request value=value

Are there struts tags we can use to compare the properties of 2 beans
(without using any jsp scriplet)?

I am a newbie
thx for you patience.
