Thanks for the help... The parameter issue you mentioned was a dumb
mistake on my part, which I've fixed.
The fixed method is below so that anyone hunting the archives has it
available:
public Collection getPartialSoftwareList() {
int startPage;
String page="";
ServletRequest request = pageContext.getRequest();
Enumeration parameters = request.getParameterNames();
while (parameters.hasMoreElements()) {
String parameter = (String) parameters.nextElement();
// Check if it's a displaytag property and specifically the
page parameter
if (parameter.startsWith("d-") && parameter.indexOf("-p") >
0) {
page = request.getParameter(parameter);
break;
}
}
try {
startPage = Integer.parseInt(page);
} catch (NumberFormatException ex) {
startPage = 1;
}
return softwareService.getPartialSoftwareList(startPage, 30);
}

I'd do this part a bit more like this:
Enumeration parameters = req.getParameterNames();
while(parameters.hasMoreElements())
{
String parameter = (String) parameters.nextElement();
if (parameter.startsWith("d-"))
{
page = request.getParameter(parameter);
break;
}
}
try
{
startPage = Integer.parseInt(page);
}
catch (NumberFormatException ex)
{
startPage = 1;
}

Overall, not really, no. You need to get the parameter and deal with
it.
The one thing I'd add is that "d-" parameters are displaytag parameters,
meaning that it's not exclusively the page. It could also indicate sort
order and other display parameters. I think there's a guide to the
various parameter formats around so that you can determine which is
which, but I don't remember where I saw that or if someone posted it to
this list or what.
