PHINMS Capabilities • Security • Audit and Logging • Routing and Delivery • Transforms WISCONSIN STATE LABORATORY OF HYGIENE

What’s Possible… A Peek at PHINMS Internals • TOMCAT (JAVA) Web application • Receiver – an eb. XML (SOAP) transport layer • Message Handler – manages payloads caught by the Receiver • Default Message Handler - built into the Receiver (Worker. Queue) • Optional Custom Message Handler (HTTP Servlet) 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! 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).

Pluggable Java Helper Classes • Plugs into Message Handler • Used for payload postprocessing (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! WISCONSIN STATE LABORATORY OF HYGIENE

Example Plug-in Helper Configuration <!– The helper class is used for payload post processing. It can have arbitrary attributes, but the classname is required --> <helper> <classname>edu. wisc. slh. phinms. helper. HIVMessage. Helper</classname> <output. Directory>C: /Program Files/Phin.
