I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

Microsoft Office has components for using in third party applications: COM Objects for C++ and Interop Assemblies for .Net programming.

Many Cache projects used to include calls to those libraries. However, recently this solution started being problematic.

There are two main reasons - legal and technical. Let’s check the details.

Microsoft technology support

Microsoft is supporting Office Automation only for desktop computing.

It shall not be used for server computing, as they offer Sharepoint for this scenario. Have a look here:

Preface: our small, but very ambitious company called “Black Mushroom Studio” came up with an idea for an e-commerce project and a mobile app that would let users pay for certain goods/services via a payment aggregator.

What we had initially: an Android app skeleton that, of course, liked communicating via HTTP and JSON, and a payment system with an API – web services with SOAP content.

Goal: make it all work together.

MQTT Client in COS

Hi All,

I've created a sample implementation of the MQTT protocol, which is now available on GitHub.

The project demonstrates MQTT client capabilities and it's written in Caché Object Script.

Any comments, bug reports are welcome! Some more enhancements (like SSL / TLS support) are planned for the near future.
