How work with iterator?

[Honzak Troubak]

Hello everybody,

I need help with Struts2 iterator.

Here is my code

<%
    Integer delka = (Integer) request.getAttribute("count");
    String img_src_prefix = "/readSponsor?id=";
    for (int i = 0; i < delka; ++i) {
        String img_src = img_src_prefix + i;   
        
        int numberOfRun = i;
%>
    
<img src="<%= img_src.toString()%>" height="50" width="50" border="0" /> 

<s:iterator value="sponsorList">
    <b><s:property value="nameSponsor"/></b><s:property value="descriptionSponsor"/><s:property value="linkSponsor"/> 
</s:iterator> 
<%
    }
%>

Forcycle gives picture and list gives describe of that picture. I need to have on one line Picture1 and describe1. At other line Picture2 describe2, etc. But i don't know how to do it.

I thing I need use IF (if line of sponsorList == numberOfRun) and in iterator I need to write something like "get propesties of that line (in my mind something like <s:property value="nameSponsor.get(numberOfRun)"/>)

I hope explain of my problem is sufficient.

Do anybody know how to do it?

thank you very much

Problem resolved, here is solution:

<%
    Integer delka = (Integer) request.getAttribute("count");
    String img_src_prefix = "/readSponsor?id=";
   Integer count = -1;
   //int numberOfRun = i;
%>

<s:iterator value="sponsorList">
    <% 
          count = count + 1; 
          String img_src = img_src_prefix + count; 
    %>  
    <img src="<%= img_src.toString()%>" height="50" width="50" border="0" /> 
           
    <b><s:property value="nameSponsor"/></b><s:property value="descriptionSponsor"/><s:property value="linkSponsor"/> 
</s:iterator>

My advice would be to avoid scriptlets (java code) in JSP's. JSP's should only deal with display logic. Other programming tasks should be taken care of in an action or business logic class.
