Real Time Information Director User Documentation

RTID Deployment
Hewlett-Packard Company 3 529618 - 002
Overview
This document describes the process for deploying the components of the Real Time
Information Director (also known as RTID or Director) to the BEA Weblogic Server
version 8.1.
The Director is a Java application that is deployed as an Enterprise application under
WebLogic. The application has the following components:
• Dispatch EJB. The EJB interface allows EJB clients to make synchronous
requests: the client submits an insert or update document or a query, and receives
a reply once the request is processed.
• Loader MDB. The MDB interface allows JMS clients to make asynchronous
requests. The client places documents in a JMS queue. The MDB reads the
documents from the queue, and the Director processes them. No response is
available from the MDB interface.
• Dispatch Servlet. The Servlet interface allows HTTP clients to make synchronous
requests: the client submits an insert or update document or a query, and receives
a reply once the request is processed. The Dispatch Servlet reads a document from
the HTTP input stream and uses the Dispatch EJB interface to process the
document and get a response.
The Director components above are packaged together in an Enterprise Application
Archive (.ear) file. This packaging gives you the flexibility to select the components you
need in your Enterprise application. You might need all three components, or just the
MDB interface, or just the EJB interface. To use the Dispatch Servlet, you also need the
Dispatch EJB interface.
In addition to the components described here, the Director includes an optional
subscription component. For information about configuring that component, refer to the
document entitled RTID Subscriptions.
