How to extract multiple columns of data in an tag ?

["SHURTLEFF,ROBERT (HP-FtCollins,ex1)" <ro...@hp.com>]

Assume that the ActionForm has the getter for the below "myhashtable" that
returns a Map.

Assume that the .value returns an Array of Strings (or whatever)

I want to build a <table> with 4 columns in it with the <logic:iterate> .

I copied the below code from the STRUTS Developers Guide:

<logic:iterate id="element" name="myhashtable">
Next element is <bean:write name="element" property="value"/>
</logic:iterate> 

Assume that a typical record is like:
Map.key = "myKey"
Map.value = [ "myvalue", "mydesc", "myotherdata" ]

But, how do I get the 0th, 1st, 2nd, etc. columns data out of the .value?

Does this work?
<logic:iterate id="element" name="myhashtable">
Next element key is <bean:write name="element" property="key"/>
Next element value 0 is <bean:write name="element" property="value[0]"/>
Next element value 1 is <bean:write name="element" property="value[0]"/>
Next element value 2 is <bean:write name="element" property="value[0]"/>
</logic:iterate> 

What if .value was a Class like 
public class myRecord{
	.getValue()
	.getDesc()
	.getOtherData()
}

How would you call the getters to get the data?

All help is appreciated.
Robert

Problem with Logic-iterate and enumeration

["struts (H2Opilot)" <st...@h2opilot.de>]

hi,
I have a List of Numbers and I like to use 3 columns and n rows.

Is there a possible way to realise this via Logic-iteration.

Normally, it look like that every next step in the iteration there is
always another row.

Like this:

<table width="100%" border="0" cellspacing="1" cellpadding="1">
<logic:iterate id="element" name="bla_f" property="numberss"
type="app.Data">

  <tr bordercolor="#333366">
      <td>
        <bean:write name="element" property="number"/>
      </td>

      <td>
****** this should be the next element of Data, but how increment the
element??  *****
       <bean:write name="element" property="number"/>
      </td>

  </tr>

</logic:iterate>
</table>

any ideas?

[Don Saxton <ds...@pacbell.net>]

try this if Map.value = { "myvalue", "mydesc", "myotherdata" }
<table>
<logic:iterate id="element" name="myhashtable">
     <tr>
         <td>Next element contains:</td>
         <logic:iterate id="strObj" name="element">

         <td><bean:write name="strObj" />   <!-- exceptionally form because
"bean" strObj is a String --> </td>
         </logic:iterate>
    <tr>
</logic:iterate>
</table>

try this if Map.value = new myRecord()
<table>
<logic:iterate id="element" name="myhashtable">
     <tr>
         <td>Next element contains:</td>

         <td><bean:write name="element" property="value"/>  </td>
         <td><bean:write name="element" property="desc"/>  </td>
         <td><bean:write name="element" property="otherData"/>  </td>
    <tr>
</logic:iterate>
</table>
