Restart your computer.

Last option, change boot order from Bios (depends on vendor) 

Bios -> Boot NVME Drive BBS Priorities  

windows 11: find esp partition free space

use cmd or powershell and use disk part to mount esp partition

C:\Windows\System32>diskpart

Microsoft DiskPart version 10.0.26100.1150

find which is esp partition

DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     C   Windows_Bon  NTFS   Partition    137 GB  Healthy    Boot
  Volume 1     D   Data_Boni    NTFS   Partition     20 GB  Healthy
  Volume 2         SYSTEM       FAT32  Partition    100 MB  Healthy    System
  Volume 3         Recovery     NTFS   Partition   1001 MB  Healthy    Hidden



select volume, it is volume 2 

DISKPART> select volume 2

Volume 2 is the selected volume. 

assign drive letter for volume 2

DISKPART> assign letter=z

DiskPart successfully assigned the drive letter or mount point.

exit, and run command dir z: and at the it will show free space ",,,,,  bytes free"

Don't forget to remove drive letter, replace assign letter=z to  remove letter=z

 

Debian 13: jakarta tomcat create servlet using Netbeans

This steps use Netbeans version 31.

to create tomcat apache project in netbeans follow these steps:

1. open your netbeans
2. File -> New Project -> java with Maven -> Web Application
3. fill "Project Name" e.g. My Servlet
4. in New Web Application -> Server click Add
5. select Apache Tomcat or TomEE
6. select your jakarta tomcat directory
7. fill username and password from tomcat-users.xml file which is has rule rolename="manager-gui"
8. Finish will return to New Web Application, then Finish 

to create a new servlet

1. From your project -> Source Packages -> <package_name>. MyServlet, right click and create New -> Servlet
2. Class Name: HelloWorld, then next
3. Servlet Name: My Servlet
4. URL Pattern: /HelloWorkd
5. This will create default response
6. run from your netbeans, and your HelloWorld will appear in browser with url http://localhost:8080/MyServlet/HelloWorld

now, we add mariadb into our project, edit Project Files -> pom.xml

     <dependencies>
        ....
        <!-- MariaDB JDBC driver -->
        <dependency>
            <groupId>org.mariadb.jdbc</groupId>
            <artifactId>mariadb-java-client</artifactId>
            <version>3.5.10</version>
        </dependency>
    </dependencies>

now edit HelloWorld.java

    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        try (PrintWriter out = response.getWriter()) {
            /* TODO output your page here. You may use following sample code. */
            out.println("<!DOCTYPE html>");
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet HelloWorld </title>");
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet HelloWorld at " + request.getContextPath() + " 0261015</h1>");
            
            // connect to db
            out.println("<p>connecting to mariadb</p>");
            
            try {
                Class.forName("org.mariadb.jdbc.Driver");
                out.println("<p>MariaDB JDBC driver FOUND</p>");
                
                try (java.sql.Connection conn =
                        java.sql.DriverManager.getConnection(
                            "jdbc:mariadb://localhost:3306/<db_name>",
                            "<db_user>",
                            "<db_password>")) {

                    out.println("<p>MariaDB CONNECTION SUCCESSFUL</p>");
                    out.println("<p>Database: "
                            + conn.getCatalog() + "</p>");
                } catch (SQLException ex) {
                    out.println("<p>Error"+ex.getMessage()+"</p>");
                }
                
            } catch (ClassNotFoundException e) {
                out.println("<p>MariaDB JDBC driver NOT FOUND</p>");
            }
            
            out.println("</body>");
            out.println("</html>");
        }
    }

run your servlet.

if no error found, you may start writing your application.  

hint: use any ai to find error in your code, copy paste code and error. but Do Not rely on it, use your instinct to fix your code, ai may made mistake.
