Applicable Releases: ThingWorx Navigate 1.6.0 to 1.7.0   Description:   Covers how to configure ThingWorx Navigate to use Windchill Authentication: Background and Prerequisites X.509 Public Key Infrastructure (PKIX) Brief Introduction Steps to configure Thingworx Navigate with Windchill Authentication: Windchill Integration Runtime Thingworx Navigate     Additional Information Navigate SSL Configuration for Windchill Authentication General Checklist

In this blog I will be testing with the WindchillSwaggerConnector, but most of the steps also apply to the generic SwaggerConnector.     Overview   The WindchillSwaggerConnector enables the connection to the Windchill REST endpoints through the Swagger (OpenAPI) specification. It is a specialized implementation of the SwaggerConnector. See Integration Connectors for documentation.   It relies on three components : Integration Runtime : microservice that runs outside of ThingWorx and has to be deployed separately, it uses Web Socket to communicate with the ThingWorx platform (similar to EMS). Integration Subsystem : available by default in 7.4 (not extension needed) Integration Connectors (WindchillSwaggerConnector) : available by default in 7.4 (not extension needed)   Currently, in 7.4, the WindchillSwaggerConnector  does not support SSO with Windchill (it is more targeted for a "gateway type" integration). Note that the PTC Navigate PDM apps are using the WindchillConnector and not the WindchillSwaggerConnector.   Integration Runtime microservice setup   The ThingWorx Integration Runtime is a microservice that runs outside of ThingWorx. It can run on the ThingWorx server or a remote machine. It is available for download from the ThingWorx Marketplace (Windows or Linux). The installation media contains 2 files : 1 JAR and 1 JSON configuration file.   For this demo, I'm installing the Integration Runtime on a remote machine and will not be using SSL.   1. Prerequisite for the Integration Runtime : Oracle Jre 8 (and of course a ThingWorx 7.4 platform server accessible) 2. Create an ApplicationKey in the composer for the Integration Runtime to use for communication to the ThingWorx platform. 3. Configure the Integration Runtime communication - ThingWorx host, port, appKey, ... - this is done on the Integration Runtime server via the JSON configuration file.   My integrationRuntime-settings.json (sslEnable=false, storagePath is ignored) : { "traceRoutes": "true", "storagePath": "/ThingworxStorage", "Thingworx": {     "appKey": "1234abcd-xxxx-yyyy-zzzz-5678efgh",     "host": "twx74neo",     "port": "8080",     "basePath": "/Thingworx",     "sslEnable": "false",     "ignoreSSLErrors": "true"   } } Note : It is important to completely remove the "SSL": {} block when not using SSL   4. Launch the Integration Runtime service (update the JAR and JSON filenames if needed) java -DconfigFile=integrationRuntime-settings.json -jar integration-runtime-7.4.0-b12.jar The Integration Runtime service uses Web Socket to communicate with the ThingWorx platform (similar to EMS). It registers itself with the ThingWorx platform.   Monitoring the Integration Runtime microservice        In the ThingWorx composer : Monitoring > Subsystems > Integration Subsystem      SMAINENTE1D1 is the hostname of my Integration Runtime server.   Custom WindchillSwaggerConnector implementation   Use the New Composer UI (some setting, such as API maps, are not available in the ThingWorx legacy composer) 1. Create a DataShape that is used to map the attributes being retrieved from Windchill WNCObjectDS : oid, type, name (all fields of type STRING)   2. Create a Thing named WNC11Connector that uses WindchillSwaggerConnector as Thing Template 3. Setup the Windchill connection under WNC11Connector > Configuration Authentication Type = fixed (SSO currently not supported) Username = <Windchill valid user> Password = <password for the Windchill user> Base URL : <Windchill app URL> (e.g. http://wncserver/Windchill)   4. Create an API maps under WNC11Connector > Services and API Maps > API Maps (New Composer only) My API Map : New API Map Mapping ID : FindBasicObjectsMap EndPoint : findObjects (choose the first one) Select DataShape : WNCObjectDS (created at step 1) and map the following attributes : name <- objName ($.items.attributes) type <- typeId ($.items) oid <- id ($.items)   After pressing [done] verify that the API ID is '/objects GET' (and not /structure/objects - otherwise recreate the mapping and choose the other findObjects endpoint). 5. Create a "Route" service under WNC11Connector > Services and API Maps > Services (New Composer only) Name : FindBasicObjects Type (Next to [Done] button) : Route Route Info | Endpoint : findObjects (same as step 4) Route Info | Mapping ID : FindBasicObjectsMap-xxxx created at step 4 Testing our custom WindchillSwaggerConnector   Test the WNC11Connector::FindBasicObjects service Note that the id (oid) and typeId (type) are returned by default by the /objects REST API - objName has to be explicitly requested.   Monitoring the Integration Connector        In the ThingWorx composer : Monitoring > Integration Connectors

Hello Navigate Community -     In case you haven't heard, Navigate 8.5 was released last Thursday, 9/26 and is now available for download! This release includes a lot of exciting functionality:   1. Improvements to View Apps -  Updated ThingView 3D Viewing Component - which is now documented & supported for use in custom mashups;  Support for distributed vaults;  Display of security labels & values. 2. BETA release of the first Reusable Components for rapid application development  3. First Navigate Contribute App for review & approval of Windchill Change Requests Want to learn more? Read on!   Introducing change can result in higher costs if not fully considered.  That’s why collaboration is a necessity across people and processes from the initial state of product ideation through to manufacturing, device connectivity and field service.  There is a need to not just access product and enterprise data easily, but to participate in strategic product lifecycle processes in order to avoid unintended consequences.   ThingWorx Navigate 8.5 introduces the first App in the Contribute Series. This App allows key stakeholders to be directly involved in the change process by enabling them to voice their opinions. The first of the Contribute apps for Change Management stitches all these voices together within the digital thread.   Inter-operable with Windchill 11.2 and Windchill 11.1 M020 CPS06, this change management app provides a list of open approval tasks and access to full details of the Change Request, along with attachments and affected items.   Configurable by role, this latest Navigate App enables a broad set of users inside and outside of engineering to fully participate in a digital change management workflow. Cross-functional users who review their task list, via “My Tasks”, are best able to complete changes online. These users can then assess change impacts at time of review, resulting in improved quality by eliminating the need to manually capture input and avoiding errors.   Role-based tailoring facilitates faster, clearer decision making and higher quality changes.  Better participation in the change management process adds the value of faster time to market. This Contribute app is the first to be built from reusable components, thus lowering costs and improving efficiency.   The Thingworx Navigate Contribute app for Change Management enables the wider spread of input to realize the best possible design since products are no longer designed in a silo.   If you have any questions about Navigate or want to connect with an account rep, reach out to me at elarkin@ptc.com.

The use of the term “SSO” means different things to different people. Among Navigate Admins, it became shorthand for using PingFederate to provide both authentication with a single sign-on component, as well as authorization (checking permissions for access to files). In Navigate 1.5, this was the only option for configuring a production system, and many people were not ready for it. That was the origin of the “must have SSO” statement. Beginning with Navigate 1.6, PTC added a scenario called “Windchill Authentication”, that is suitable for Production and uses your Enterprise LDAP to authenticate users. It will issue a token so you get some of the benefits of single sign-on, but not all the bells and whistles that come with PingFederate. It’s also easier to configure. People have begun referring to Windchill Authentication as “non-SSO”, to distinguish it from PingFederate, even though Windchill Authentication has some SSO functions.   In the install manual, there are three scenarios: Fixed Authentication, Windchill Authentication, and Single Sign-On with PingFederate. People usually begin with Fixed Authentication (the easiest to configure, but not secure so it’s only good for Proof of Concept demonstrations), then do Windchill Authentication before tackling PingFederate. Windchill Authentication can take a couple of days while Webexing with us to get working, but for PingFederate we plan several Webexes over a period of 8 days for a typical install. During that time you will be coordinating with other administrators (such as the AD admin) and waiting for emails etc. to get remote admin tasks done as part of the install. Be prepared, timewise.
