& 2D String Array without a Form Bean

Hi Guys,

Sorry to ask such a basic question but i've searched the archive and failed 
to find a suitable answer to my question so heres my problem:

I'm having some trouble getting <logic:iterate/> to work with a 2D String 
array when using it without a form bean. Heres what i'm trying to do:

I have an action which inserts a two dimensional String Array (i.e. 
tabledata) in to the request.



In my JSP i do the following:

<logic:iterate id="datarow" name="tabledata" indexId="counter">
	<tr>
		<td><bean:write name="<%=datarow[counter][0]%>"/></td>
          	<td><bean:write name="<%=datarow[counter][1]%>"/></td>
        </tr>
</logic:iterate>


Any ideas???

Why don't you just extend one that already supports most of what you want to
do?

i think to do that , you must write a new tag java class (extends
"TagSupport" class)and in this class you will use a java code of the 2
other classes ( select and option).

and after this you will declare your new tag in the tld file.

Something like this :

public class PoweredSelectTag extends SelectTag {

    /**
     * Add a sumbit button after the select list
     */
    public int doEndTag() throws JspException {
        ... (code taken from other tags, like SubmitTag) ...
    }

}

Re: Tag Extension

Posted by Nicolas De Loof <ni...@cgey.com>.
As you cannot inherit two classes, I don't think you can "re-use" this
two existing tags code. You could create a new SumitTag instance to
get it's code running from your tag, calling it's setters and
doStart/doEnd methods, but I really don't think it's a good idea (I
sometimes have very bad ideas).

IMHO copying half the code will not be so bad, as struts tag allready
use common tools (RequestUtils...) and you will so have to learn using
them !

A large number of the standard Struts tag implementations follow the
"extend via subclass" approach.  For example, many of the HTML tags have a
common set of attributes for all the CSS and JavaScript features, and the
tag attribute properties for these are defined in a common base class
(org.apache.struts.taglib.html.BaseHandlerClass).

When subclassing tag classes, I have found it most convenient to
completely re-implement the doStartTag() and doEndTag() methods.  The
value of the subclass is not having to redo the property getter/setter
methods, or the utility methods that are usually in protected scope.  Some
of the Struts tag implementations split out important stuff into such
utility methods (for example, LinkTag splits out the creation of the
actual URL into a calculateURL() method), but the factoring could be
improved in future versions of the implementations.

I was looking at that possibility, but, if doing so, my own tag should
redefine all setter property for the original tags: the html:select tag,
for example has a style attribute; If I use it as a private object
inside mine, I have to redefine the getStyle and setStyle methods; this
of course is still valid for all other attributes. 

It is maybe better to extend one of the tags i want to use, and then add
code, as suggested by Nicolas...
What I don't like in this solution is I don't really reuse code (In the
Nicolas example, code from SelectTag is reused, but for writing a Submit
button I have to copy, or write my own code ...)

You mean something like: ??

Public class SelectPlusButton extends TagSupport
{


	doStartTag(...)
	{
		// Write out a table definition...
		SelectTag st = new SelectTag();
		st.doStartTag(..);
		...
		ButtonTag bt = new ButtonTag();
		bt.doStartTag();
		....
	}
}

i think to do that , you must write a new tag java class (extends
"TagSupport" class)and in this class you will use a java code of the 2
other classes ( select and option).

and after this you will declare your new tag in the tld file.

Take a look at sub folders under struts
src/shared/org/apache/struts/taglib. You might want to subclass some of
the tag classes + all the necessary work for defining a tag, e.g. tld.

What is the standard way to "extend" a struts tag, or generally whatever
jsp tag ? Do I have to extend the Java class Implementing that tag ? To
be more clear: in my application I have to often use a select/options
struts tag, together with a button, so it would be useful in the jsp
page to only use one construct.
Any ideas ?
Thanks a lot.

Renato

P.S.: I know, this is not really a struts question, but I think it would
be of interest ...
