Serious performance impact with iterator
Hey All,
I'm wondering if anyone else is seeing this impact.
I've got an iterator within an iterator thusly:
<table border='1' cellpadding='0' cellspacing='0'
style='BORDER-COLLAPSE: collapse' bordercolor='#111111'>
<logic:iterate id="rowArray" name="batchForm"
property="rowBatchDetails" indexId="rowCount">
<tr align="center"
bgcolor='<%=rowCount.intValue()%2==0?"#ffffff":"#dddddd"%>'>
<logic:iterate id="colArray" name="rowArray" indexId="colCount">
<logic:equal name="colCount" value="0">
<td align='left' width='165' class='normaltxt'
height="20"> <!-- last name -->
<a
HREF="batch.do?action=Prospect&prospectChoice=<%=rowCount%>"
target="_top">
<bean:write name="colArray" /></a>
</td>
</logic:equal>
<etc ...>
</logic:iterate>
</tr>
</logic:iterate>
</table>
The resulting html looks like the following. Note all the empty spaces.
Needless to say, this has impacted performance on the website
significantly by increasing the size of the page to something ludicrous
when I have more than 20 rows of data to display!
Anyone have a solution for this? A patch somewhere?
<table border='1' cellpadding='0' cellspacing='0'
style='BORDER-COLLAPSE: collapse' bordercolor='#111111'>
<tr align="center" bgcolor='#ffffff'>
<td align='left' width='165' class='normaltxt' height="20">
<!-- last name -->
<a HREF="batch.do?action=Prospect&prospectChoice=0"
target="_top">
Aiken</a>
</td>
<td align='left' width='150' class='normaltxt' height="20"> <!--
first name-->
<a HREF="batch.do?action=Prospect&prospectChoice=0"
target="_top">
Glenda</a>
</td>
<and more of the same ...>

Can you switch to using the JSTL tag <c:forEach> instead of logic:iterate?
I use that and don't have multiple blank lines showing up on each iteration.
You could also put a Filter on the webapp and remove extraneous spaces from
the outbound HTML response.
