InstantiationException

[Dong Hoang]

Does anyone know why am I getting this exception?

E SRVE0026E: [Servlet Error]-[bean message not found within scope ]: java.lang.InstantiationException: bean message not found within scope

I have a drop down list with 4 sort options within my jsp. When a selection is made the "onchange=doSort()" javascript function is called and submit to my servlet.

 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").toUpperCase();
//String sortProperty = req.getParameter("sortProperty");
HttpSession session = req.getSession();

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

//if ((sortProperty.equals("")) || (sortProperty == null)) {
//sortProperty = (String) session.getAttribute("sortProperty");
//} else {
//session.setAttribute("sortProperty", sortProperty);
//}

// 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);
// 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);
}
}
}

I suspect that the problem may be within the ShowException.jsp file. Check the useBean tags on that page to make sure that they are correct.

Why are you not using declarations in the web.xml to direct errors rather than this non-standard mechanism?

I am not familiar with web.xml. Do you have an example that you can point me to?

Thanks for the quick respond.

Now I am getting a NullPointerException on this line

String claimNo = req.getParameter("claimNo").toUpperCase();
