This is a web based XMPP chat client with basic security labelling within the XEP-0258 spec (using hardcoded security labels rather than discovering the catalog).
To build the chat client package run the following:
cd chat_client mvn clean package
chmod u+x build.sh
build.propertiesfile and customise as required.
cp *.war chat.war
chat.warinto your applcation server.
If the build customisation fails, delete
chat.war and repeat step 6 onwards.
