Java Business Host is now retired

With the release of PEX in InterSystems IRIS 2020.1 and InterSystems IRIS for Health 2020.1, customers have a better way to build Java into productions than the Java Business Host. PEX provides a complete set of APIs for building interoperability components and is available in both Java and .NET.

The Java Business Host has been removed from InterSystems IRIS and InterSystems IRIS for Health as of their 2020.4 releases.  Customers using the Java Business Host are encouraged to migrate to PEX.

Using the Java Gateway to speed development

InterSystems IRIS includes dynamic object gateways for Java, .NET, and (now) Python.  These gateways allow your IRIS application to use libraries in these languages, removing the need to create everything from scratch in ObjectScript.

In this example, we use the iTextPdf and Apache PdfBox libraries to read a text file and produce a basic PDF from it.  These libraries are deep and rich PDF controls, so a little bit of development could produce an example application that produces far more compelling results for your needs.
