Module Definition

Contents

The file module.xml defines the module structure as seen by FirstSpirit servers. It contains information about the FirstSpirit Module (FSM) itself, including name, version number and vendor, as well as segments on each individual plug-in component.

It follows a mandatory XML structure that specifies which Java classes included in the FSM file implement plug-in interfaces and will be advertised to ContentCreator. Furthermore, the XML mark-up is used to define resources that should be included in the roll-out process of plug-in code to a project-specific ContentCreator web application.

Example: module.xml

Important In the ContentCreator Example module framework, the file module.xml is stored at the module's root directory. If you wish to move this file, you must also modify the Ant build configuration so that it can be located while assembling the FSM file.

</module>

This file, which is a shortened version of the module definition file used to build the FirstSpirit Module “WebEdit Example Plug-Ins”, specifies basic information about the FSM itself (name, version, description and vendor), two plug-in components (one of type public, the other of type web-app) as well as one resource (fs-we5examples.jar, referenced both as a resource of the web-app component as well as of the FSM itself).

The component specified in the <public> block of this file will be used by the ContentCreator module manager to identify which plug-in actions are available in each user interface context, while the <web-app> block of this file specifies at least one JAR file and, optionally, further files that will be rolled out to the ContentCreator web application upon deployment. The tags available in each block are described in the section Component Model.

<depends></depends>

 

within <dependencies>

A dependency on another FirstSpirit Module; the block contains the dependency module's name (as defined in its <name> block).

    

"service" component type

The service component type is used to specify a server-wide service. The component definition requires specification of a Java class which implements the Service interface of the FirstSpirit Developer API.

Specifies the path (relative to the WebEdit web application's WEB-INF directory) and file name of one or several JAR files that contains the module's classes as resources; additionally, other application server-compatible files (such as JSP files) may be specified. All files specified here will be rolled into the WebEdit application's WAR file at server start-up or application deployment.

    

"web-app" component type

The web-app component type is used to specify a web application. Specific to ContentCreator plug-ins, this component is used to roll out plug-in components as a JAR file to a location ContentCreator can access during server start-up (as the global or a project-specific ContentCreator application is started)--during start-up, the contents of this and other modules' JAR files are added to the ContentCreator code set that will be used by the application server.

Important FirstSpirit Modules which provide ContentCreator extensions must include at least one component of type web-app. These web-app components are used to roll out JAR files containing the extension components' classes into the global or project-specific ContentCreator web applications.

Component Blocks

The following component types may be specified within the XML block <component>. Each component type implies a specific use, and thus each type requires certain sets of XML tags.

"public" component type

The public component type is used to specify all module components that implement client extension interfaces. For each class that implements an individual plug-in, a separate <public> block is specified in module.xml.

Important At least one component of the type public must be specified in the module description of a FirstSpirit Module that provides client plug-ins.
