drop down list

[Dong Hoang]

What is the best way of doing this? I have a drop down list with 4 values in the jsp. Whenever a selection is made, I need to set the value selected in the list box after processing. Here is the jsp and servlet code.

package gov.state.il.us.pe.AL_ALSPkga;
 
import java.io.IOException;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
 
public class pealPeopleListing extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
performTask(req, resp);
}
 
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
performTask(req,resp);
}
 
public void performTask(HttpServletRequest req, HttpServletResponse resp) 
throws ServletException, IOException {
try {
// Get input parameter
String claimNo = req.getParameter("claimNo");
String sortProperty = req.getParameter("sortProperty");
HttpSession session = req.getSession();

if (claimNo == null) {
claimNo = (String) session.getAttribute("claimNo");
} else {
session.setAttribute("claimNo", claimNo);
}

// Retrieve list of people and store in an array
pealPeopleListSearchBean peopleList = new pealPeopleListSearchBean();
peopleList.setSearchCriteria(claimNo);
peopleList.setSortProperty(sortProperty);
pealPeopleType[] people = peopleList.executeSearch();
req.setAttribute("people", people);
req.setAttribute("sProperty", sortProperty);
// Call the presentation renderer
getServletContext().getRequestDispatcher("/ALSReports/PeopleListing.jsp").forward(req, resp);
} catch (Exception e) {
req.setAttribute("message", e.getMessage());
req.setAttribute("forward", "../ALSReports/People.jsp");
getServletContext().getRequestDispatcher("/ALSReports/ShowException.jsp").forward(req, resp);
}
}
}  

CODE] <SCRIPT language="JavaScript">
function back()
{
window.navigate("../servlet/gov.state.il.us.pe.AL_ALSPkga.pealInvalidatePeopleSession");
}

function doSort()
{
document.peopleListingForm.action="../servlet/gov.state.il.us.pe.AL_ALSPkga.pealPeopleListing";
document.peopleListingForm.submit();
}
</SCRIPT>

ltSELECT name="sortProperty" onchange="doSort()">
<OPTION value="1">SSN Ascending</OPTION>
<OPTION value="2">SSN Descending</OPTION>
<OPTION value="3">Last Name Ascending</OPTION>
<OPTION value="4">Last Name Descending</OPTION>
</SELECT>[/CODE]

One way of doing it might be to define a method on your bean that compares its parameter to the sortProperty property and returns the String "selected" if they match. You could then use it in each of the OPTION tags as follows:

<OPTION value="1" <%= myBean.sortOptionSelected(1) %> >SSN Ascending</OPTION>

I'm not sure that's the most elegant way of doing it, however.
