hibernate print data from session object arraylist

hibernate print data from session object arraylist - java

I made wrong HQL trying to access column from another table. Sorry.
This question is solved.
I have ArrayList of type Object. Fetched from session.
It exists. I check. But I cant print it it from jsp or java. even I create methods.
// with type List I cant even fetch information from session. A change it to ArrayList.
My goal is to print result. I select some sql columns and I just wanna output them. Of course it would be object.
I have no error and that is problem. Only existing arraylist object of my type prod.
ArrayList <prod> goodlist = (ArrayList <prod>) session.getAttribute("goodlist_s");
for (prod glst : goodlist) {
%>
<tr>
<td><%//=out.println(u.getname())%></td>
<td><%=glst.getcatid()%></td>}
I try convert it to String ArrayList .
ArrayList<String> jlistTitles = new ArrayList<String>((ArrayList<String>) session.getAttribute("goodlist_s")); //converted fine
for(int i = 0; i < goodlist.size(); i++) {
System.out.println(goodlist.get(i).getprice());
//print object type
}
**Shows nothing**
This is my function
#SuppressWarnings("unchecked")
public static ArrayList<prod> getListOfProds(String catname,String name,Integer pricel, Integer priceh){
ArrayList<prod> list = new ArrayList<prod>();
Session session = HibernateUtil.openSession();
Transaction tx = null;
try {
tx = session.getTransaction();
tx.begin();
Query query = session.createQuery("from prod where catname=?");
query.setString(0, catname);
//query.setInteger(1, pricel);
//query.setInteger(2, priceh);
list = (ArrayList<prod>) query.list();
tx.commit();
} catch (Exception e) {
if (tx != null) {
tx.rollback();
}
e.printStackTrace();
} finally {
session.close();
}
return list;
}
BTW i would sent all code

Java Hibernate application using mySQL- Login page does not work

I am working on a hibernate project using apache.tomcat in netbeans in which I am creating an application with a user login (employee ID and password) that allows baseball field employees (from mysql database) to request passes to use the field. Users should be able to 1) choose an event for reservation (date & time) from a drop down menu, 2) input their group size, group name, and employee department(drop-down) and 3) manage the reservations on file specific to their employee ID.
I can access the login screen, but nothing happens when I enter employee credentials. I am not sent to the memberscreen.jsp upon entering a correct login, and I do not get the errors I set up for invalid logins. I have been at this for hours and I can not seem to find where I went wrong.
Note: The project requires that I use hibernate
I have tried googling ways to fix this but I have come up short, I think my problem may be too specific. I am getting no errors and the build is successful, but not functional.

Problems with Glassfish5 and servlet

I'm relatively new to Java. Tried my first web application with server Tomcat, which went rather well. However, with another server Glassfish, problems arouse. After application deployment jsp doesn't connect to servlet, therefore error 404 appears. I added project structure and several classes. Any help appreciated.

Spring MVC wrong entity id after an attempt to update it

I try to write simple Spring MVC CRUD webapp and I got a problem updating my rows. I have a table with some users and I can edit any of them clicking "Edit" button in the table (look at the picture). Then I can change its fields in a form, but when I click "Edit" under the form, the id of user entity, that is conveyed to the addUser() method, is 0, though, when I got the entity from db, it wasn't. Also "createdDate" field becomes null. I can't find out the reason of it, so I need some help... This is my code and the picture with my app:

I have no idea where the problem may be, so if you need more code, I'm ready to write it. Thanks

I solved this. I had to add <form:hidden path="id" /> to the id input field. I suppose I need to do the same with createdDate field.

value map is not a member of models

Hi I'm trying to fetch a object from a class and displaying it and I'm getting error "value map is not a member of models.TimeSheetDataStore"
Here is my model class files
TimeSheetDataStore.java
package models;
public class TimeSheetDataStore {
String ID;
String EmployeeID;
String RoleID;
String Task;
String TimeSheetDate;
String CreateDate;
String UpdateDate;
String TaskHour;
String IsBilled;
String ClientID;
String ProjectID;
String atHome;
String atClientSite;
}
TimeSheet.java
package models;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;
import models.TimeSheetDataStore;
public class Timesheet {
public static List<TimeSheetDataStore> PopulateProject() {
List<TimeSheetDataStore> TimeSheetList = new ArrayList<TimeSheetDataStore>();
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433","SUMEET","sumeet");
Statement sta = conn.createStatement();
String Sql = "select * from Project";
ResultSet rs = sta.executeQuery(Sql);
while (rs.next()) {
TimeSheetDataStore TSDS= new TimeSheetDataStore();
TSDS.ID=rs.getString("ID");
TSDS.EmployeeID=rs.getString("EmployeeID");
TSDS.RoleID=rs.getString("RoleID");
TSDS.Task=rs.getString("Task");
TSDS.TimeSheetDate=rs.getString("TimeSheetDate");
TSDS.CreateDate=rs.getString("CreateDate");
TSDS.UpdateDate=rs.getString("UpdateDate");
TSDS.TaskHour=rs.getString("TaskHour");
TSDS.IsBilled=rs.getString("IsBilled");
TSDS.ProjectID=rs.getString("ProjectID");
TSDS.ClientID=rs.getString("ClientID");
TSDS.atHome=rs.getString("atHome");
TSDS.atClientSite=rs.getString("atClientSite");
TimeSheetList.add(TSDS);
}
} catch (InstantiationException | IllegalAccessException
| ClassNotFoundException |SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return(TimeSheetList);
}
}

Can some one tell me what I'm doing wrong?

try instead of
#for(i <- currentPage.indices) {
#for(element <- currentPage.get(i)) {
<tr>
<td>#element.ID</td>
<td>#element.EmployeeID</td>
<td>#element.RoleID</td>
.
.
.
</tr>
}
}
use only one for loop because you have list of currentPage: List[TimeSheetDataStore] so when you do #for(element <- currentPage) it will return you one object assigned to the element variable so now you have TimeSheetDataStore object in element variable so you can directly access it's fields
Do it like this:
<tbody>
#for(element <- currentPage) {
<tr>
<td>#element.ID</td>
<td>#element.EmployeeID</td>
<td>#element.RoleID</td>
<td>#element.Task</td>
<td>#element.TimeSheetDate</td>
<td>#element.CreateDate</td>
<td>#element.UpdateDate</td>
<td>#element.TaskHour</td>
<td>#element.IsBilled</td>
<td>#element.ProjectID</td>
<td>#element.ClientID</td>
<td>#element.atHome</td>
<td>#element.atClientSite</td>
</tr>
}
</tbody>
