I have a problem transferring data between two jsp
There are two controllers in which the first one accepts the input data, second generate lines with using this params
First controllers group receives two params
#RequestMapping(value = "/create", method = RequestMethod.POST)
public String ProjectSizePost(
#RequestParam("countSprints") Integer countSprints,
#RequestParam("countWorkers") Integer countWorkers) {
BigInteger a = BigInteger.valueOf(countSprints);
return "project/project_size";
}
#RequestMapping(value = "/create", method = RequestMethod.GET)
public String projectSizeGet() {
return "project/project_size";
}
And his jsp
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<%--<c:forEach var="inputLine" begin="1" end="4">

</c:forEach>--%>
<form action="/project/show_size" method="post" name="/project/show_size"

</form>

Second controller and jsp must take params from first jsp
#RequestMapping(value = "/create", method = RequestMethod.POST)
public String createProject(
#RequestParam("projectId") Integer id,
#RequestParam("name") String name,
#RequestParam("startDate") String startDate,
#RequestParam("endDate") String endDate,
#RequestParam("projectStatus") OCStatus projectStatus,
#RequestParam("projectManagerId") Integer projectManagerId) {
MapperDateConverter mdc = new MapperDateConverter();
*//*Project project = new Project.ProjectBuilder()
.projectId(BigInteger.valueOf(id))
.name(name)
.startDate(mdc.convertStringToDate(startDate))
.endDate(mdc.convertStringToDate(endDate))
.build();
project.setProjectStatus(projectStatus);
project.setProjectManagerId(BigInteger.valueOf(projectManagerId));*//*
//projectDao.createProject(project);
return "project/create";

I'm having a bit of trouble with changing html pages to jsp with corresponding changes to the servlet. Usually I have not had an issue with this, but I am now trying to access the database and display tables.
Firstly, the html, corresponding servlet and dao which all works fine.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

This is the part of the servlet used, TableFormatter is a class located within a jar file in the Libraries package.
else if(action.equals("bid")){
AuctionDAO dao = new AuctionDAO(ds);
String itemID = request.getParameter("Items");
String bidderID = request.getParameter("Bidders");
double bidAmount = Double.parseDouble(request.getParameter("bidValue"));
try{
boolean bidRecorded = dao.regBid(itemID,bidderID,bidAmount);
if(bidRecorded){
out.println(formatPage("Your Bid for " + bidAmount + " was recorded"));
}
else {
out.println(formatPage("Your Bid could not be registered"));
}
}catch(Exception ex){
out.println(ex.getMessage());
}// end catch
}// end if
else if(action.equals("viewBids")){
// AuctionDAO dao = new AuctionDAO(ds);
String itemID = request.getParameter("Items");
try{
ResultSet rs = dao.viewBids(itemID);
out.print(TableFormatter.getData(rs));
}catch(Exception ex){
out.print(ex.getMessage());
}// end catch
}// end if
private String formatPage(String message){
StringBuffer output = new StringBuffer();
output.append("<html><head><title>Auction Admin</title></head><body>");
output.append("<h1>" + message + "</h1>");
output.append("</body>");
output.append("</body></html>");
return output.toString();
}
and then, the dao
public boolean regBid(String itemId, String bidderId, double amount)throws SQLException{
int recsInserted = 0;
regBidQuery();
regBidPS.setString(1, bidderId);
regBidPS.setString(2,itemId );
regBidPS.setDouble(3, amount);
recsInserted = regBidPS.executeUpdate();
if(recsInserted == 1){
return true;
}
else {
return false;
}
}
private void regBidQuery()throws SQLException{
regBidPS = con.prepareStatement("INSERT INTO USER1.TBids " +
"VALUES(?,?,?)");
}
Now, All of this works perfectly fine. My jsp pages even work with the new servlet code, but I can't seem to get how to access the TableFormatter class or the regBids() method.
Jsp's:

And this is how I am now running the servlet code - as you can see, the code I have generates the same content as the original html pages, it's just accessing the db and displaying the table and messages that I can't figure out.
if(action.equals("viewbids_view")) {
HttpSession session = request.getSession();
session.setAttribute("items", dao.getItems());
response.sendRedirect("ItemBids.jsp");
}
else if(action.equals("bid_view")) {
HttpSession session = request.getSession();
session.setAttribute("items", dao.getItems());
session.setAttribute("members", dao.getMembers());
response.sendRedirect("Bids.jsp");
}
I'm pretty sure this is the problem, but where do I look to resolve the issue?
I have an application where in a JSP page i am displaying a drop down list but i am getting an exception in my code.

I am getting the below exception :-
javax.servlet.jsp.JspException: Type [java.lang.String] is not valid for option items
org.springframework.web.servlet.tags.form.OptionWriter.writeOptions(OptionWriter.java:143)
org.springframework.web.servlet.tags.form.OptionsTag.writeTagContent(OptionsTag.java:157)
org.springframework.web.servlet.tags.form.AbstractFormTag.doStartTagInternal(AbstractFormTag.java:84)
It is just a Spring MVC Web application where i am trying to display the drow down list pre-populated with the colors data.
Any help is highly appreciated.
I added the below line on teh top of addDetails.jsp file and it worked:-
Try to add into Map, instead of ArrayList.
Map<String,String> coloursList = new HashMap<String,String>();
coloursList.put("R","red");
coloursList.put("R","green");
coloursList.put("Y","yellow");
coloursList.put("P","pink");
I wrote a jsp project, tried to execute it. I got this error:
listType cannot be resolved to a variable
So I added this lines to my jsp file:
<%#page import="java.util.List"%>
<%#page import="java.util.ArrayList"%>
But it didn't fix the problem. How can I fix it?
There is one more error like this:
The method StudentDetails() is undefined for the type
MangeUser Student.jsp
Here is Student.jsp:

How can I fix those 2 errors?
I have a JSP called create-account.jsp which collects a customer's details and sends the data to a Servlet. The Servlet inserts the customer's data into the database, queries the database add sets the results as request scoped attributes and the dispatches to create-account.jsp(same jsp). Now the inserted details must appear in a hidden html table in the jsp. How do I do it? Can any one help?

Use
style="visibility: hidden;"
or
style="display:none;"
to hide the table.
for more info have a look at below links
CSS Display and Visibility
Show/Hide div javascript
How to show the result in table?
sample code:
Servlet:
public class Model{
private String name;
private String dob;
private double balance;
// getter and setter
}
...
List<Model> list = new ArrayList<Model>();
//add the data in list
request.setAttribute("list",list);
JSP:
<c:if test="${not empty list}">
<c:forEach var="ob" items="${list}">
<tr>
<td><c:out value="${ob.name}"/></td>
<td><c:out value="${ob.dob}"/></td>
<td><c:out value="${ob.balance}"/></td>
