Architecture Overview

The Adapter is a Java Servlet application that executes with a Servlet Engine Web Application Server and has extensions to the already in-situ PTC ™ Windchill system.

A typical corporate network with the deployed adapter might resemble the architecture shown in the figure below.

Figure: A Typical Architecture

The RLIA integrates modern Internet Web Service components to provide the OSLC capabilities required by its nature as an OSLC consumer and provider of Engineering Lifecycle Management information. The significant components that it integrates are:

Technology Source Purpose
OASIS OSLC Specifications for OSLC CM REST Protocols
Eclipse Lyo OSLC4J Libraries
Apache Tomcat Tomcat Web Server Manager
IBM WebSphere Application Server IBM Web Server Manager
AngularJS Client-side Browser User Interfaces
Restangular Client-side REST Broker
ParseUri Javascript URI Parsing
LoDash Functional Javascript CDN Fallback and Lazy Loading
Bootstrap Client-side Responsive CSS
OWASP HTML Policy Server-side Java HTML Filtering
OWASP CSRF Filtering Server-side CSRF Management

Software composing the Adapter is provided as OSGi bundles loaded into an OSGi engine that is, itself, provided as a Web Archive that is managed by a web application servlet engine. For example, an organization can choose to use Apache Tomcat or IBM Websphere Application Server as the Servlet Server that hosts the RLIA’s OSGi engine.

The following table illustrates the OSGi bundles of the RLIA adapter.
