Welcome to OXClient-lib

OXClient-lib is a Java library with a higher and lower API to connect to the Open-Xchange Community Edition via its HTTP API. The main focus is for use in rich client applications but there are also some helper classes for use in web applications.

The higher API gives you a full abstraction of the Open-Xchange HTTP API. You don't need to know anything about the HTTP API. You just deal with, hopefully, self explaining interfaces and classes. For a jump start with the higher API see the quickstart guide.

The lower API gives you the ability to communicate with the HTTP API in a simple query like way. You don't have to deal with http connections, request creation or parsing the response.

See the user manual for a full description and examples.

Usage Note

This API is in per alpha state! Don't use it in productive environments, because it will change in the near future. The first stable release will be the 0.5.0 release. See the roadmap for more details.
