I am trying to get individual data from database using group by method in hql but query executed successfully and also it does not display on the respective web page what is the problem in the above code and also how to use group by in Hibernate and Spring Mvc application and also inform what is wrong with the mapping.

1) You query should have the same column ins group by as in the select (excluding the count):
select count(tx.driver.driverid),tx.driver.drivername
from Transaction tx
group by tx.driver.drivername
2) You are trying to perform a projection but you are expecting a List of Transaction. By default the persistence provider will return a List<Object[]> and you will need to extract manually the count column and the drivername column.
3) Alternatively you could use a ResultClass feature -> example

Spring Boot & Thymeleaf returning empty list to controller

Making a Spring Boot + Thymeleaf application.
I'm trying to pass a list of IDs of the type Integer to my controller based on whether is it checked on a form, in order to delete one or more rows of data from my db table.
However, right now it returns an empty list.
The ID is the primary key of the table.
The controller seems to be working fine because when I manually add an Integer to the list - it can be deleted with no problem.

thanks.
I see the javascript function calls id="tblGrp". However,
<div id="tblGrp">
<table width="70%" id="tblGrp" align="center" class="sortable">
The id appears multiple times, perhaps giving a problem with jspdf. Without more information of the javascript error, Here are a couple of java alternatives.
1) You can build everything using iText.
2) You can design a report in iReport by constructing a jrxml and use the jasper engine for independent pdf exporting/rendering in your application.
3)Here is additional post for alternative to iText.
[Are there any Java PDF creation alternatives to iText?
Without more info of the javascript error, there isn't much to solve here.

multiple errors while executing a jsp project

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

Here is Student.jsp:

Hi, Here is my code:
import java.awt.Desktop;
import java.io.File;
public class Start extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {
try {
if ((new File("C:\\Debug\\log20.txt")).exists()) {
Process p = Runtime
.getRuntime()
.exec("C:\\Debug\\log20.txt");
p.waitFor();
} else {
System.out.println("File is not exists");
}
System.out.println("Done");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
Web.xml:
<servlet>
<servlet-name>LogFile</servlet-name>
<servlet-class>com.abc.def.LogFile</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LogFile</servlet-name>
<url-pattern>/logfile</url-pattern>
</servlet-mapping>

You Could you try it like this if you want to browse the file in an external program
Process p = Runtime.getRuntime().exec("C:\\Path\\to\\notepad.exe C:\\Debug\\log20.txt");
And if you want to browse the file in web page you could try the following:
PrintWriter out = res.getWriter();
File file = new File("C:\\Debug\\log20.txt");
if (file.exists()) {
BufferedReader input = new BufferedReader(new FileReader(file));
String line = "";
while ((line = input.readLine()) != null) {
out.println(line);
}
}
