FileNet Web Services provide a web services automation layer between an Active Server-based Process application (via PJAC for FileNet Web Services) and a client (via the Microsoft Internet Information Server (IIS)). To access an ASP-hosted application in a web browser on the client, a user logs into the web server and either launches a workflow or participates in an already-running workflow. Client HTTP requests that do not require interaction with the Process Engine via a Java™ applet/application are passed through an active MS IIS session to the FileNet Web Services and PJAC for FileNet Web Services components, which send them via the Process Java APIs and the JiGlue COM Bridge to the ASP-hosted application.
Note: Refer to your FileNet Web Services documentation for complete information about FileNet Web Services.
If a Java™Script object on the client requests an IDM object from FileNet Image Services or Content Services, FileNet Web Services retrieves the object via Remote Procedure Calls (RPCs) for return via IIS to the client.
The first time the client accesses FileNet Web Services, the software forces an automatic download of the Process Java APIs, the Process applets, the client-side JavaScript, and the Java™ Runtime Environment.
The following additional components are also necessary to use FileNet Web Services:
The JiGlue COM Bridge acts as a translation layer between the Process Java APIs and COM. The JiGlue COM Bridge provides the ability to instantiate COM objects using the Process Java APIs. Using the JiGlue COM Bridge you can make COM calls that are equivalent to native Java statements. For additional information, see Developing with the JiGlue COM Bridge.
The Process Java Applets Connectivity (PJAC) component combines Java and an interface to the ASP-hosted application and the automation layer of FileNet Web Services. PJAC provides the Process integration services and connectivity (client-side Javascript and Process applets) between FileNet Web Services and the Process Engine. PJAC is installed by running the PJAC installer on the Web server. See the topic Install Process Java Applets Connectivity in the IBM FileNet Image Manager Process Installation Guide.
