Java Business Host is now retired

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.

Advantages of PEX

  • Allows developers to create any Production component in either Java or .NET
  • More complex message structures can be passed between components
  • Simplified settings
  • Simplified development workflow with no need for ObjectScript.

For more information on migrating to PEX, please see Migrate from Java Business Host to PEX.
