votes

I am trying to make a simple Hello world application using Activiti eclipse BPMN Designer 5.9. I made a activiti project in eclipse and added my check.bpmn diagram to src/main/resources folder and my .java to src/test/java and activiti.cfg.xml files to the src/test/resources folder. The application is just suppose to show alert "Hello" to the console, but I cannot seem to get it to do this. Below if all the files that I am using to run the application. I don't know what i am missing.I have installed Activiti Eclipse BPMN 2.0 designer.

UPDATE:

i have added jar files enter image description here

The error

Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \ )

tells you your String is invalid.

private String filename = "C:\Users\User\workspace\Proj\src\main\resources\diagrams\Check.bpmn";

should be escaped

private String filename = "C:\\Users\\User etc...";

You have to convert project to maven project. After that you will see "Maven Dependencies" in your project and class path.

To convert try right button on project name -> context menu -> Configure -> Convert to Maven project.

Check maven dependencies in you project structure. check if activiti-engine-{activiti-version}.jar is available or not.
