According to what you suggested
I created the below in the action
String row1[][] = {{"type1","currency1","amount1"},
{"type2","currency2","amount2"},
{"type3","currency3","amount3"},
{"type4","currency4","amount4"},
{"type5","currency5","amount5"},
};
and set it's value to the form bean (i.e Form1) attribute which is
private String[][] rows;
public void setrows(String[][] rows) {
this.rows = rows;
}
public String[][] getrows() {
return rows;
}
not really sure how to iterate now in jsp? how do I populated the data now?
under the columns type, currency, amount??
<logic:iterate id="rowid" property="rows">
<tr>
</tr>
</logic:iterate>
Thanks.

thankyou for your responses.
for my Jsp I created a formbean and for ---- Form1
with attributes
name
row[]
table row in the jsp created another formbean.--- Form2
with attributes
type
currency
amount
In the action I created dummy data
Form2[] ----- row[] and set it to the form1 attribute
I'm not sure I understand what you're doing here. Are you saying that Form1
and Form2 are ActionForm subclasses, and that 'row' in Form1 is an array of
Form2 instances? And that the JSP is rendering a single form, part of which
is shown in a table? In that case, Form2 doesn't have to be a form bean
(ActionForm instance), it can be any arbitrary java bean -- or you could
have Form1 declare three arrays named type[], currency[] and amount[].
There's lots of options here, depending on exactly what you're trying to
achieve. That said, if I understand what you have then it should work.
Now I am not sure how this row[] values to be displayed using struts in
the jsp. i mean how to loop thru this to get values.
To loop through a colllection of values, you would use the
<logic:iteratate> tag from Struts [1] or, if you have it available, the
<c:forEach> tag from JSTL.
Maybe you could post your code, JSP and struts-config.xml so we can see
more clearly what you're doing.
HTH,

I would appreciate your help.

thanks.

A couple of gotchas concerning TagLibs
what version JSP container ?
if its 2.0 then consider JSTL 1.1.x tags
On the other hand the struts html tag library outstrips anything
available from JSTL
But if you want performance steer clear Struts logic: tags as they rank
slowest of all available Logic Taglibs
If you are concerned about being tied into a TagLib that doesnt
accomplish everything you want to do go with scriptlets
and wait for JSF Tag Library
Good Luck,
Martin-

I am new to web development and struts too.
I am trying to create a jsp which has
a text field for display only for Name
and a Table below it with couple of rows and columns in it.
how many form beans do I have to create?
Do I have to create one for the jsp and one for the table alone?
do I have to use nested tag? not really sure. if so how do I have to
use this in jsp?
It's really up to you to a large extent. You can have a single form bean
for an entire application if you want. One for each page that has a form
on it is probably typical though.
The User Guide section on developing view components [1] may help you
get a better overall understanding of what your options are.
I'm not sure when you say 'nested tags' if you're referring to the
'nested' tag library, or if you just mean having tags nested inside
other tags. Assuming the former, no, you don't necessarily need to use
them, though they may make some things easier. I'd suggest getting to
grips with the basics first and then looking at the 'nested' taglib
again later, when you'll be better able to understand if what it offers
applies to what you're doing.
