jacob does not support linux; jacob is the abbreviation of "JAVA-COM Bridge". It is a middleware that can provide automatic access to COM components and "Win32 libraries" under MS systems, and jacob only supports windows. Linux is not supported.
#The operating environment of this tutorial: linux7.3 system, Dell G3 computer.
Does jacob support linux?
Jacob now only supports windows, not linux
The jacob package should be for windows if you download it. The file description containing .0s can be used under Linux. However, since
is based on JNI, the system library must be called. How can there be a system library such as word under Linux?
Jacob can only be used in It is used under the windows platform, so you must be clear about this premise before writing a program

Jacob Introduction
Jacob It is the abbreviation of JAVA-COM Bridge. It is a middleware that can provide automatic access to COM components and Win32 libraries under MS systems.

Class Diagram
Core Class
JacobObject: Used for COM communication under Java program MS to create a standard API framework
ComThread: Initialize the COM component thread, release the thread, and manage the thread
Dispatch: Scheduling processing class, encapsulates operations to operate Office, and represents different MS level scheduling objects
ActiveXComponent: Create COM components
Variant: Parameters or return values for communication with COM
ROT: Running Object Table (ROT), the running object table maps each thread to all jacobobjects, created in the thread
Core method
-
Dispatch: The properties or methods of the automation object can be called. For specific properties and methods, please refer to the reference document VBA API
Dispatch.get(dispatch , String name); Get object properties
Dispatch.put(dispatch, String name, Object value); Set object properties
Dispatch. call(dispatch, String name, Object… args); call object method
- 3. Flowchart
- Advantages
-
- Relative to OpenOffice, the conversion effect is good,
- relatively For POI, you can operate Word/Powerpoint
- Easy to use, refer to the VBA API to use Jacob to operate COM components
Insufficient -
- Slow conversion speed
- High CPU usage (100% single CPU usage)
- WORD may deadlock under concurrent conditions (Microsoft Knowledge Base)
- Word macro security issues

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Linux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.

The steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.

The core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.
