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.
                      java.lang.Integer 0 = null&#59;
                               ^
There is some thing wrong with <logic:iterate> tag
I need help please!!
