Installing the extension on macOS

Installing the extension in a custom folder

There are several methods for loading the Java extension from a custom directory on macOS, similar to the process on a Windows environment.

While these examples are based on a Java application named JavaDisabledElements launched from a .jar file, they are applicable to other applications as well.

Using command-line parameters

This method is applicable across all versions of Java, including Java 9 or greater:

/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/bin/java -cp /Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport/UiPathBridge.jar:/Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport/UiPathV8.jar:/Users/example/Documents/UiPath/Driver/Qa/UiPath.Driver.Tests/open/TestApps/JavaDisabledElementsApp/JavaDisabledElements.jar -Djavax.accessibility.assistive_technologies=UiPath.UiPathBridge JavaDisabledElements/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/bin/java -cp /Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport/UiPathBridge.jar:/Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport/UiPathV8.jar:/Users/example/Documents/UiPath/Driver/Qa/UiPath.Driver.Tests/open/TestApps/JavaDisabledElementsApp/JavaDisabledElements.jar -Djavax.accessibility.assistive_technologies=UiPath.UiPathBridge JavaDisabledElements

Expected output:

Java resources directory: /Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport
tryLoadFromPredefinedPaths
UiPathJavaBridge Interface DLL loaded from: /Users/example/Documents/UiPath/Driver/MacOS/Output/UiPathJavaBridgeV8.dylib

UiPathJavaBridge Interface DLL loaded from: /Users/example/Documents/UiPath/Driver/MacOS/Output/UiPathJavaBridgeV8.dylib
Java Version: 1.8.0_401
UiPath Access Bridge started

Using environment variables

If the Java runtime supports the extension loading mechanism, you can use environment variables. Here is an example: 

export JAVA_TOOL_OPTIONS=-Djava.ext.dirs=/Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport -Djavax.accessibility.assistive_technologies=UiPath.UiPathBridge

/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home/bin/java -jar /Users/example/Documents/UiPath/Driver/Qa/UiPath.Driver.Tests/open/TestApps/JavaDisabledElementsApp/JavaDisabledElements.jarexport JAVA_TOOL_OPTIONS=-Djava.ext.dirs=/Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport -Djavax.accessibility.assistive_technologies=UiPath.UiPathBridge

/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home/bin/java -jar /Users/example/Documents/UiPath/Driver/Qa/UiPath.Driver.Tests/open/TestApps/JavaDisabledElementsApp/JavaDisabledElements.jar

Expected output:

Loading UiPathBridgeInterface Dll
Java resources directory: /Users/example/Documents/UiPath/Driver/MacOS/Output/JavaSupport
tryLoadFromPredefinedPaths
UiPathJavaBridge Interface DLL loaded from: /Users/example/Documents/UiPath/Driver/MacOS/Output/UiPathJavaBridgeV8.dylib

UiPathJavaBridge Interface DLL loaded from: /Users/example/Documents/UiPath/Driver/MacOS/Output/UiPathJavaBridgeV8.dylib
Java Version: 1.8.0_401

For native macOS applications

For native macOS applications, parameters can be added by editing the Info.plist file. This can be done only where applicable.

Here is an example where we used an application called SAPGUI for Java and extension files from a Driver Portable build for macOS:
