Nested loops

[saurav sarkar]

Hi All,
I want to implement nested loop in Struts please
tell me how can i achieve this by struts tags.

I have a VO called LeadVO which contains a string and
an array of strings.
First i want to iterate over the size of the collection of the VO objects.
Then for each String i want to iterate over the array of strings.

I tried to look into the logic tags i am not able to get that
please help.

    <logic:iterate id="xyz" name="Arralist" >
            <logic:iterate id="new arraylist" name="xyz">
                <bean:write name="<new arraylist>" property="<>" />
            </logic:iterate>
    </logic:iterate>

thanks Jibitesh for the reply.
i think i am missing out something.

 
<logic:iterate id="xyz" name="Arralist" >            <logic:iterate id="new arraylist" name="xyz">                <bean:write name="<new arraylist>" property="<>" />            </logic:iterate>    </logic:iterate>

acc to this, the property will be the 'the string of arrays'.
It wont work i think.I am getting errors for it.
Please help

My JSP code

<logic:iterate id="lead" name="leadlist" >

<th>
 <bean:write name="lead" property="project_lead" />
  </th>
 <logic:iterate id="empname" name="lead">
 <tr align="left">
 
 <bean:write name="empname" property="employeeName" />
 <tr>
</logic:iterate>
</logic:iterate>

the property employeeName is the array String.
please help to put Array of Strings in the correct way in the JSP.

Thanks in advance,
Saurav
