Hola Ignacio,
Welcome to the list.
Usually, the best way to get started is to download the ZIP or EXE version of BaseX and follow the instructions in our documentation [1]:
• If you start the BaseX GUI, you can create databases, run queries, view your data via various visualizations, etc. • If you start the BaseX HTTP Server, you can simply open your browser and visit http://localhost:8984/dba/ to access the web-based administration interface.
Now some more specific replies on your questions:
I’ve been trying to configure the web administration portal to be used with a remote server with no success. It looks like it is not possible to take advantage of the client-server architecture from the Web Application http://docs.basex.org/wiki/Web_Application
What kind of remote server do you work with? Indeed BaseX provides a client/server architecture – which will be made available after starting the BaseX Server – but I assume you are rather interested in the HTTP services, such as RESTXQ? Have you already tried to embed BaseX as a servlet?
