Creating rules XML file

A rules xml file needs to be created with all rules which you would like to provide with your component. An example of the rules xml file is:

<?xml version="1.0" encoding="UTF-8"?>
<cjforum>
	<activity_type>
		<name>com_cjforum.topic_reply</name>
		<appname>com_cjforum</appname>
		<title>Reply to a topic</title>
		<description>Activity about new topic reply.</description>
		<state>1</state>
		<access>1</access>
		<language>*</language>
	</activity_type>
</cjforum>

Save this file as administrator/components/com_mycomponentname/cjforum_rules.xml. You can package the xml file with your component so that it will be automatically installed along with your component. After installing the file, users can scan for rules and the rules will automatically gets installed. The same xml file may contain multiple activity rules as well as points rules.
