UiPath Studio

Extension for Java


For Java 9+, the UiPath Extension for Java works on Windows Enterprise and non-Enterprise editions with applications opened with Java JDK. For applications opened with Java JRE, the UiPath Extension for Java only works on non-Enterprise Windows editions. Read more on the Java Extension Troubleshooting guide.

The UiPath Extension for Java is installed by doing the following:

  1. First, close any running Java applications. Launch Studio and access the Tools tab from the Studio Backstage view. The extensions you can install become visible. Click the Java Extensions button. A confirmation message appears, informing you that the extension has been installed.
  2. Run this command C:\Program Files (x86)\UiPath\Studio\UiPath\SetupExtensions.exe /Java in a command prompt window with administrator rights.

Studio and UI Explorer also ask to install the UiPath Extension for Java when you try to select a control inside a Java app and when the bridge is not detected. Please note that if you choose to install the UiPath Extension for Java when prompted by UI Explorer the Java Bridge files get deployed only in the JRE directory which launched the target Java application instead of the JDK directory.


To install this extension you must have administrator rights.

To check if the extension is not working properly, open UIExplorer and try to select controls inside a Java app. If the entire window is selected, it means that the extension is not working properly.

You can tell whether or not the extension is properly installed by the generated selectors for Java controls.

<wnd app=”...” /><java role=”...” />
<wnd app=”...” /><ctrl role=”client” />


The UiPath Extension for Java is compatible only with AWT apps (e.g. Java Swing, Oracle Forms, Fujitsu JBK), while SWT apps are automated with Active Accessibility. To detect the type of your Java application, check the cls attribute (window class name) in UI Explorer. The class name should be similar to SunAwtFrame or javax.swing.

Processes can interact with Java applications regardless of their DPI scaling.

The UiPath Extension for Java can also be installed using the ScreenScrapeJavaSupport tool.
