HTTP File Upload Component

About

This application allows occupants of an XMPP multi-user chat room to share data (images and such) with each-other.

More specifically, this is a Jabber Component that implements XEP-0363: HTTP File Upload

Download

The compiled application, as well as the source code, is available for download on the 'releases' page of this project.

Building

This project is using a Maven-based build process. To build this project yourself, ensure that the following are available on your local host:

• A Java Development Kit, version 8.
• Apache Maven 3

To build this project, invoke on a command shell:

$ mvn clean package

Upon completion, the application will be available in the target directory.

Usage

To run the application, execute

java -jar httpfileuploadcomponent-<versionnumber>-jar-with-dependencies.jar

A number of arguments can (and probably should) be added. A common execution is:

java -jar httpfileuploadcomponent-<versionnumber>-jar-with-dependencies.jar \
   --xmppHost openfire1.example.org \
   --sharedSecret hqcUrfHtgE73FktcXwfrP

This will start the application, connect it to an XMPP server with the provided shared secret, and launch a webserver on a non-local interface of the machine on which the application is executed.

When end-users should interact with the webserver using a different address, the announcedWebHost argument can be used. This provides a convenient way to work with remote proxies or port-forwarded network topologies.

A full set of usage instructions are provided by adding the --help argument:

$ java -jar httpfileuploadcomponent-1.0-jar-with-dependencies.jar --help
