Many plugins take advantage of the online web server
to generate images.
For some reasons (security, performance...) you may need to use your own local server instead. This is possible thanks to the PlantUML Server which is available here
However, installing and configuring a full webserver may be too complex for some users so we have decided to integrate a tiny webserver inside
This means that you only need a Java Runtime Environment and
to run this very simple web server.
Running the server is pretty simple. You just have to launch:
java -jar plantuml.jar -picoweb
By default, this server runs on port
. You can change the port this way:
java -jar plantuml.jar -picoweb:8000
The server is really
basic. It only understands GET requests with following patterns:
Those GET requests are used by various PlantUML plugins. Once you have launched your server, you can simply test it. With any web browser, you just have to point to:
This way, you can very easily use any plugins which need some PlantUML HTTP server without
the official online server.
