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

• 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

##Excellent Disadvantages

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
