GlassFish ESB Components in the PIX/PDQ Manager

Sun's PIX/PDQ Manager uses various components of GlassFish ESB such as HTTP, JMS, and HL7 Binding Components; the BPEL Service Engine; Composite Applications; Java EE EJBs; and Sun Master Index. The solution includes the following GlassFish ESB components:

• Sun Master IndexThe Sun Master Index provides patient identifier cross-referencing and unique identification of patient records. It also maintains a centralized repository of each patient's most current information. You can customize many features of the Master Index, such as the queries, match and standardization logic, the data fields stored, and how the single best record for each patient is formed.

• PIX ConsoleThe PIX Console is a system management and monitoring tool that allows you to view records in the ATNA audit repository, the PIX/PDQ processing log, message traces (how each message was processed through the PIX/PDQ Manager). The console includes a Domain Manager that allows you to update and add information about the systems, or domains, that share information in the PIX/PDQ system, including domain identification information, subscriptions to outbound notifications, and application configurations and variables.

• BPEL Service EngineThe BPEL Service Engine orchestrates services to define the processing flow and business logic of messages through the PIX/PDQ system, including routing and transforming data, mapping data fields, and calling the appropriate functions from other PIX/PDQ components. The BPEL processes also write the required data to the ATNA audit repository, and are responsible for generating HL7 ACK/NACK responses. Each BPEL process is specific to either HL7 v2 or HL7 v3.

• HL7 Binding ComponentThe HL7 Binding Component supports the HL7 messaging structure up to version 2.6 and defines the communication protocols for connecting to the HL7 messaging systems The HL7 Binding Component in the PIX/PDQ Manager is configured to use the Minimal Lower Layer Protocol (MLLP) version 1 to connect to external systems.

• HTTP Binding ComponentThe HTTP Binding Component supports the HL7 v3 messaging structure and defines the communication protocols for connecting to the HL7 messaging systems. The HTTP Binding Component in the PIX/PDQ Manager uses the SOAP 1.1 and 1.2 protocols to connect with external systems.

• JMS Binding Component: The JMS Binding Component is used for PIX outbound notifications published by Master Index. Notifications are published to JMS topics and then distributed to all subscribed domains.
