Release notes

v2.0.0​

Release date: July 22, 2025

Breaking change​

Starting with the 2.0.0 release of the Java activity package, support for the.NET 4.6.1 framework has been discontinued. As a result, this and all subsequent package versions cannot be used for Windows-Legacy projects. Restrict package usage to Windows or cross-platform projects exclusively.

Package versions released before this date continue to support.NET 4.6.1 as per the following deprecation timeline.

v1.3.1​

Release date: August 25, 2021

Improvements​

The Java activity package is now compatible with.NET 5 Windows.

The activities in this pack now support SecureString parameters.

v1.2.0​

Release date: January 13, 2021

New features and improvements​

A new property, Init timeout (miliseconds), was added to the Java Scope activity in order to prevent null references before the environment is up and running.

Bug fixes​

  • The Invoke Java Method activity can now invoke Generic methods.
  • In the Invoke Java Method activity you can now call methods with null values for parameters, which produced an error until now.

v1.0.6856.22995​

Release date: October 9, 2018

New features and improvements​

Being one of the most used programming languages, we have now integrated Java into our product in the form of some new activities. This new addition to our ever-growing pool of languages enables you to invoke your already existing Java code directly from UiPath. The Java activity package features six new activities and a proprietary variable, JavaObject, that help you harness the full power of Java into your automation projects:

  • Java Scope - Initializes a specified Java library and provides a scope for Java Activities. All Java activities must run inside a Java Scope.
  • Load Jar - Loads a Java Library Package file in the current Java Scope for subsequent actions. A method can be invoked only after its respective class library is loaded.
  • Invoke Java Method - Invokes a specified Java method from a .jar loaded in the Java Scope. The result is stored in a JavaObject variable.
  • Convert Java Object - Converts a JavaObject into a .NET primitive data type. Only primitive .NET types and Arrays of primitive .NET types are supported.
  • Create Java Object - Creates a JavaObject variable from a class by using the builder specified in the TargetType property field. The class must be defined in the .jar supplied in the Load Jar activity.
  • Get Field - Returns a public field from a specified JavaObject variable or from a public static field inside a class.

The moment is finally here - the entire UiPath Platform has been localized, so that you can have a truly immersive experience, from install to design and execution. Now, besides English, you can access everything, including our online documentation, in Japanese.
