            <td>
                <a href="admin-devicetypeedit?dTID=${deviceType.ID}" class="badge rounded-pill bg-primary">
                    <i class="fa fa-edit"></i>
                    Edit
                </a>
                <form action="admin-devicetypedelete" method="POST" onsubmit="return confirm('Are you sure you want to delete this item?');">
                    <input type="hidden" name="dTID" value="${deviceType.ID}">
                    <button type="submit" class="badge rounded-pill bg-danger">
                        <i class="fa fa-trash-o">Delete</i>
                    </button>
                </form>
            </td>
        </tr>
    </tbody>
</c:forEach>

But i show "deviceType cannot be resolved"

Can you help me/Thanks for all

could you show how you are rendering that jsp page? based on the message, sounds like `deviceType` is not set — Gastón Schabas, May 16 '23 at 02:57

You can get the variable from the pageContext.

LocalDateTime stopTime = ((DeviceType) pageContext.getAttribute("deviceType")).getStopTime();
// replace DeviceType with the type of the variable deviceType
