Hot to use <logic:iterate> tag to retrieve specific index value in struts

Hi,

  I have added vector to request object in the action class, i added 3 elements to the vector.

I wanted to access this vector in a jsp page. I am using <logic:iterate> tag to access the specific element of the vector

this is my code
<logic:present name="<%= WebConstants.MESSAGE_COUNTS_HDR %>" >
<logic:notEmpty name="<%= WebConstants.MESSAGE_COUNTS_HDR %>" >
    <TD valign="TOP" class='TableText' height="12">
         From <logic:iterate id="hdrVec" name="<%=WebConstants.MESSAGE_COUNTS_HDR %>" indexId="0" /> to <logic:iterate id="hdrVec" collection="<%=WebConstants.MESSAGE_COUNTS_HDR %>" indexId="1" />
     </TD>
</logic:notEmpty>
</logic:present>

It's giveing the following error.
enerated servlet error:
C:\Documents and Settings\Z001532\My Documents\IBM\wsad\workspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\localhost\server1\iaInfoServices\iaInformation.war\_rptMsgCounts.java:257: Invalid expression statement.

jarasa i am awarding the points to you.
I hope you will try to give answers from next time onwards instead of the links.
Unfortunately opache has poor documentation. They did not give any examples.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
