What is it? || Description

This tool validates BPMN models against the officially provided XSDs of the OMG and a subset of the descriptive extended constraints from Geiger (2013).

Additionally, the tool checks the schema validity of all in a BPMN file imported WSDL and XML files. Namely, the following constraints of Geiger identified by their ids can be checked through this tool:

1, 2, 6-9, 21-23, 25, 26, 28, 31, 36, 56, 76, 79, 84, 88, 95-109, 135, 146, 150, 151, 152

Requirements and Installation

First, at least Java 7 is required to use the program.

Next, JAVA_HOME must be set, included into your PATH and point to your JAVA installation for the console usage.

Lastly, this tool supports Gradle usage.

Validation

You can use the validator in two ways, either stand-alone or as API.

Via Console

The stand-alone validator must be used via console. It prints debug loggings if --debug is added to the JAR invoking. Additionally, the validator needs a number of files, which should be validated. Their paths have to be added as parameters to the JAR call and must be separated by a whitespace, so that the validation works correctly. The results of every file validation is saved as validation_result_name_of_the_validated_file.xml in the folder of the validated file.

An example of the console call is the following: java -jar bpmnvalidator.jar my_bpmn_file.bpmn The path to the file(s) can be either relative to the path of the bpmnvalidator.jar or absolute.

Via JAR

Alternatively, you can include the validator into your project and use it as API. The JAR can be easily created by gradle build or gradle jar and is then located in \build\libs. Next, you have to get a reference to the validator instance through BpmnValidatorFactory.getValidatorInstance() and then you can call on this object the methods shown below:

/**
 * Interface for the implementation of the validator. Allows the usage of the
 * validator in other projects. The loglevel is set default to info. If you need
 * another log level, change the log level before the validation process.
 *
 * @author Philipp Neugebauer
 * @version 1.0
 *
 */
public interface BpmnValidator {

	/**
	 * returns the set loglevel of all loggers
	 *
	 * @return the set log level {@link ch.qos.logback.classic.Level}
	 */
	Level getLogLevel();

	/**
	 * Sets the loglevel of all loggers of the bpmn validator to the given level
	 *
	 * @param logLevel
	 *            possible levels: {@link ch.qos.logback.classic.Level}
	 */
	void setLogLevel(Level logLevel);

	/**
	 * checks the given xmlFile for bpmn constraint violations
	 *
	 * @param xmlFile
	 *            the xml file to validate
	 * @return ValidationResult including all checked files and found violations
	 * @throws BpmnValidationException
	 *             if something fails during validation process
	 */
	ValidationResult validate(File xmlFile) throws BpmnValidationException;

	/**
	 * checks the given xmlFiles for bpmn constraint violations
	 *
	 * @param xmlFiles
	 *            the list of xml files to validate
	 * @return list of {@link de.uniba.dsg.bpmn.ValidationResult} including all
	 *         checked files and found violations for each file
	 * @throws BpmnValidationException
	 *             if something fails during validation process
	 */
	List<ValidationResult> validateFiles(List<File> xmlFiles)
			throws BpmnValidationException;

}

Therefore, code including this tool will look like the following:

BpmnValidator v = BpmnValidatorFactory.getValidatorInstance();
v.setLogLevel(Level.INFO);
try {
	v.validate(new File("FilePath"));
	//or
	v.validateFiles(new ArrayList<File>());
} catch (BpmnValidationException e) {
	// handle
}

Documentation

The documentation of the tool can be easily created by executing gradle javadoc and is then located in \build\docs\javadoc.

Structure of Software/Repository

The repository is structured in the following way:

|- gradle: contains the gradle wapper
|- lib: all libs required for the tool which aren't uploaded to maven central
|- src
|-- main
|--- java: contains all java classes
|---- de.uniba.dsg.bpmnspector.common: contains the result classes of the validation
|----- xsdvalidation: contains the xsd validator classes for the specific file types
|---- de.uniba.dsg.ppn.ba: contains the main class for API usage
|----- api: contains the factory class
|----- helper: contains all the helper classes required for both preprocessing and validation step
|----- preprocessing: contains the classes performing the preprocessing step
|----- validation: contains the classes performing the validation steps
|--- resources: contains all schema validation files
|-- test
|--- java: contains all test classes named by their test case
|--- resources: contains all test files sorted in folders by their test case

Developing Helpers

There are different helper classes to debug and simplify developing:

PrintHelper.java: prints the results in a nice way

TestMain.java: allows the simplified testing and presentation of validation results

import java.io.File;

import de.uniba.dsg.bpmn.ValidationResult;
import de.uniba.dsg.ppn.ba.helper.PrintHelper;
import de.uniba.dsg.ppn.ba.validation.SchematronBPMNValidator;

public class TestMain {

	public static void main(String[] args) throws Exception {
		File f = new File(TestHelper.getTestFilePath() + "002" + File.separator + 
			"success_import.bpmn");
		SchematronBPMNValidator validator = new SchematronBPMNValidator();
		ValidationResult result = validator.validate(f);
		System.out.println("Is File " + f.getName() + " valid? "+ result.isValid());

		if (!result.isValid()) {
			PrintHelper.printViolations(result.getViolations());
		}

	}
}

Further Development

This program is merged in the BPMNspector and will be further developed in this repository.

You can’t perform that action at this time.
