To start or stop the information center, use the Infocenter class. The class can be used as a stand alone program, launched from a command line, or can be instantiated and used from a Java program.
To start, stop the stand alone help system or cause it to display help on a user machine, use the Help class. The class can be used as a stand alone program, launched from a command line, or can be instantiated and used from a Java program.
There is a general mechanism (defined at the plug-in level) by which individual plug-ins contribute on-line help and context-sensitive help for their component. This Eclipse mechanism for contributing help content needs to be used. The stand alone help system is responsible for accessing this information and displaying it to the user. The information center, unlike the stand alone help system, does not launch UI on the machine that it is running on. When infocenter is started the help content can be obtained by connecting to a help server (port specified in Tomcat plugin preferences) using HTTP connection.
