8. WISCONSIN STATE LABORATORY OF HYGIENE What’s Possible… A Peek at PHINMS Internals TOMCAT (JAVA) Web application Receiver – an ebXML (SOAP) transport layer Message Handler – manages payloads caught by the Receiver Default Message Handler - built into the Receiver (WorkerQueue) Optional Custom Message Handler (HTTP Servlet)

9. WISCONSIN STATE LABORATORY OF HYGIENE HTTP Servlet Message Handler A way to address Routing and Transform issues! Example code in the PHINMS 2.6.0 Technical Reference. Provides access and control to Message queues and replies. Has direct synchronous access to the payload, OS, the universe and everything!

10. WISCONSIN STATE LABORATORY OF HYGIENE Building a Message Handler Servlet Use an IDE (Eclipse) Include appropriate PHINMS JARS from WEB-INF/lib Explore PHINMS JARS to leverage tested and approved PHINMS API’s for queue management, encryption, xml parsing, etc. Use XML configuration similar to sender/receiver. Provide dynamically pluggable class hook for payload post-processing. Incrementally test independent of PHINMS (e.g. call servlet on non-PHINMS app server within the IDE).

15. WISCONSIN STATE LABORATORY OF HYGIENE Pluggable Java Helper Classes Plugs into Message Handler Used for payload post- processing (synchronous, not polled!) Single re-usable Message Handler Load and configure using Message Handler’s XML entry (properties). Can provide post-processing feedback to PHINMS sender using the Application status. Can perform ANY function within response window!

It can have arbitrary attributes, but the classname is required --> edu.wisc.slh.phinms.helper.HIVMessageHelper C:/Program Files/PhinMS.2.8.00/shared/labarc3/out/ www.slh.wisc.edu/fileshare dummy_user dummy_password HIV.xls true Thomas Dunnick,Joe Blow,Mary Doe
