RE: How to open ms-word by Vaadin and write some data and pictures onto m

You could maybe look into
JACOB
or
POI HWPF / XWPF
, but I can tell you it’s not going to be simple.

How to open ms-word by Vaadin and write some data and pictures onto ms-word ?

Depends on what you want to do.

If you want to write into Word documents, then use
Docx4J
.

If you want to open Word as a process and call its functions, use Jacob as Olli mentioned above.

Neither of those, however, is something Vaadin does. Vaadin is generally a presentation framework.
