Java Error on Robot Execution

Hi, I'm trying to execute a robotic process that open and close Outlook, but I receive this message [ERROR] 2020-06-16 15:58:20 - - java.lang.reflect.InvocationTargetException

Anyone know what could be due to it? I attach my short code here:

Java class:

			server = JidokaFactory.getServer();
			client = IClient.getInstance(this);
			outlook = IJidokaOutlook.getInstance(this);

			return IRobot.super.startUp();
		} catch (Exception e) {
			throw new JidokaFatalException("Error startUp");
		}
	}

	@Override
	public String[] cleanUp() throws Exception {
		try {

			client.killAllProcesses("outlook.exe", 1000);
			return new String[0];
		} catch (Exception e) {
			throw new JidokaFatalException("Error cleanUp");
		}
	}

	/**

	 */
	public void init() {
		try {
			// Default pause after typing or using the mouse

			client.pause(PAUSE);

		} catch (Exception e) {
			throw new JidokaFatalException("Error initializing");
		}
	}

	public void openOutlook() throws Exception {
		try {
			outlook.open();
			client.pause(PAUSE);
		} catch (JidokaMsOutlookException e) {
			throw new JidokaFatalException("Error opening Outlook");
		}

		}
	}

	/**

	public void end() {
		server.debug("Robot finished!");
	}

  • This problem sometimes happens when the actions in the workflow are not corrected linked to the code.  Maybe the name of a method has been changed.

    Do you see at the end of your exception something similar to ?

    "Caused by: java.lang.NoSuchMethodException:"

    If not, can you paste the whole exception?

  • The Exception is Caused by java.lang.NoClassDefFoundError: Could not initialize class com.jacob.activeX.ActiveXComponent

    but I put the dll in the folder C: \ AppianRPA, where there is also the agent. I also tried to insert it in the Support files of the robotic process.
