how to pass a value from one jsp in tiles to another jsp in different tiles definition in Struts 2

I want to send data from a link in a jsp page to another jsp page.As the data is in a jsp page in a link and there are 3-4 of them as they show data that is fetch from database.

<a href="Product" ><%= str1[0] %></a> 
<a href="Product" ><%= str1[1] %></a> 
<a href="Product" ><%= str1[2] %></a> . 

The str1[] is an array of String that contain the data item fetch from the database. Now , as soon as i click this link, it will go to struts.xml struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" 
"http://ift.tt/1tkDVrF">
<struts>

    <package name="default" extends="tiles-default">  
        <action name="home" class="com.deviceous.Success1">
            <result name="success" type="tiles">Home1</result>
        </action>

        <action name="Product" class="com.deviceous.Success1">
            <result name="success" type="tiles">Product1</result>
        </action>
    </package>
</struts>

Then it will find an action mapped with the same name and then proceed further to a class

import com.opensymphony.xwork2.ActionSupport; 
public class Success1 extends ActionSupport 
{ 
   public String execute() 
   { 
   return "success"; 
   } 

}`

function will be will return success and then the struts will pass control to tiles.xml tiles.xml

<?xml version="1.0" encoding="UTF-8" ?> 

<!DOCTYPE tiles-definitions PUBLIC `"-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN" 
"http://ift.tt/19E1atl"> 
<tiles-definitions>

   <definition name="Home1" template="HomePageJSP/HomePage.jsp">
      <put-attribute name="header"  value="/HomePageJSP/Header.jsp"/>
      <put-attribute name="leftMenu" value="/HomePageJSP/LeftMenu.jsp"/>
      <put-attribute name="body"   value="/HomePageJSP/Body.jsp"/>
      <put-attribute name="footer"   value="/HomePageJSP/Footer.jsp"/>
   </definition>

<definition name="Product1" template="ProductJSP/Structure.jsp">
      <put-attribute name="header"  value="/HomePageJSP/Header.jsp"/>
      <put-attribute name="leftMenu" value="/HomePageJSP/LeftMenu.jsp"/>
      <put-attribute name="body"   value="/ProductJSP/Body.jsp"/>
      <put-attribute name="footer"   value="/HomePageJSP/Footer.jsp"/>
   </definition>


</tiles-definitions>

which will send to a layout which contains body.jsp .

Now i want to access the data about which link was clicked in the starting in body.jsp.

Any help will mean a lot . Thank you.
