I am trying to run the example workflow included at the bottom of the page [here](https://activities.uipath.com/docs/about-the-java-activities-pack) and it is not running properly. I get passed the Java Scope activity, so I believe the path to the JDK is correctly appended to my PATH environment variable. The error I am getting occurs in the first Invoke Java Mathod. It is saying that “The method could not be invoked.” And if I click on the details button it tells me “The target type was not found” I don’t understand what the problem is, I question whether or not this example even works for anyone else. I also don’t understand what Objects.jar is being referenced in the Load Jar activity. This .jar file does not exist anywhere in what is downloaded from the “About the Java Activities Pack” page. Please advise, any help would be greatly appreciated. ---

Is it possible to get an updated example that works? I think there is significant value in utilizing Java within automations. My colleague had a client scenario in which she had to use values from a Java method, and she was able to figure it out but it would be great to have a simple point of reference from UiPath. 🙂 ---
