Iterating Hashmap in jsp and Showing Data in Dynamically Generated Table - hashmap

Question

I am having hashmap in jsp.
I want to print all the values that hashmap contains in a table. The table should generated dynamically and after 3 columns next values should be displayed in next row and so on..Using jstl or any tag library.
So if hashmap contains 6 values then HTML generated should be:
<table>
<tr>
<td> val1 </td>
<td> val2 </td>
<td> val3 </td>
</tr>
<tr>
<td> val1 </td>
<td> val2 </td>
<td> val3 </td>
</tr>
</table>
If hashmap contains 8 values then HTML generated should be:
<table>
<tr>
<td> val1 </td>
<td> val2 </td>
<td> val3 </td>
</tr>
<tr>
<td> val4 </td>
<td> val5 </td>
<td> val6 </td>
</tr>
<tr>
<td> val7 </td>
<td> val8 </td>
</tr>
</table>
So as per number of values the number of rows should get added to table. How do I do that in jsp... either using jstl tags or any custom tag library?

Answer 1

Simply add the following java code in your jsp
<table>
<%
int count=0;
Iterator itr = yourMap.iterator();
while(itr.hasNext()) {
String key = itr.next();
if(count ==0) {
%>
<tr>
<% } %>
<td><% =yourMap.get(key) %></td>
<%
count ++;
if(count ==3 ) {
count =0;
%>
</tr>
<%>
}
</table>
Here I am assuing your map is <String,String> and please import relevant classes for map and iterator. Any JSP tutorial can tell you how o do that
