Error while using LogHelper to parse a .xes file #6

Closed davidglavas closed 5 years ago

davidglavas commented 5 years ago

I'm trying to use LogHelper to parse the BPI 2012 dataset:

    public static void main(String[] args) {

        XLog targetLog = null;

        String filePath = "financial_log.xes";

        // attempts to parse with universal Parser
        LogHelper t = new LogHelper();

        try {
            t.checkFile(filePath);  // makes sure that specified path is correct

            targetLog = t.readXes(filePath);    // parses .xes file, stores it as Xlog

        } catch (LogFileNotFoundException e) {
            System.out.println("File not Found, check the filepath. ");
            e.printStackTrace();
        } catch (ParsingException e) {
            System.out.println("Error while parsing the file. ");
            e.printStackTrace();
        }

        System.out.println("Dataset is loaded.");       
    }

When running this I get the following error message:

I don't understand the problem. Am I using the parser incorrectly?

My final goal is to use the loaded XLog file and call something like the mine() method from here. Is this possible? Note that I don't have ProM installed.
