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
plantuml.jar. This means that you only need a Java Runtime Environment and
plantuml.jarto run this very simple web server.
java -jar plantuml.jar -picoweb
Attention: By default, the server listens on all interfaces on port
8080. To change the default behavior, you can specify a colon separated port (still listening on all interfaces) or, both, a port and a bind address:
java -jar plantuml.jar -picoweb:8000 java -jar plantuml.jar -picoweb:8000:127.0.0.1
The server is really basic. It only understands GET requests with following patterns:
http://127.0.0.1:8080. This way, you can very easily use any plugins which need some PlantUML HTTP server without the official online server.
