I am new to activiti and wanted to start with the 10 minutes tutorial in eclipse. I installed the activiti plugin and created a new activiti project with a new class containing the code of the tutorial
public class TenMinuteTutorial {
public static void main(String[] args) {
// Create Activiti process engine
ProcessEngine processEngine = ProcessEngineConfiguration
.createStandaloneProcessEngineConfiguration()
.buildProcessEngine();
// Get Activiti services
RepositoryService repositoryService = processEngine.getRepositoryService();
RuntimeService runtimeService = processEngine.getRuntimeService();
// Deploy the process definition
repositoryService.createDeployment()
.addClasspathResource("FinancialReportProcess.bpmn20.xml")
.deploy();
// Start a process instance
String procId = runtimeService.startProcessInstanceByKey("financialReport").getId();
// Get the first task
TaskService taskService = processEngine.getTaskService();
List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("accountancy").list();
for (Task task : tasks) {
System.out.println("Following task is available for accountancy group: " + task.getName());
// claim it
taskService.claim(task.getId(), "fozzie");
}
// Verify Fozzie can now retrieve the task
tasks = taskService.createTaskQuery().taskAssignee("fozzie").list();
for (Task task : tasks) {
System.out.println("Task for fozzie: " + task.getName());
// Complete the task
taskService.complete(task.getId());
}
System.out.println("Number of tasks for fozzie: "
+ taskService.createTaskQuery().taskAssignee("fozzie").count());
// Retrieve and claim the second task
tasks = taskService.createTaskQuery().taskCandidateGroup("management").list();
for (Task task : tasks) {
System.out.println("Following task is available for accountancy group: " + task.getName());
taskService.claim(task.getId(), "kermit");
}
// Completing the second task ends the process
for (Task task : tasks) {
taskService.complete(task.getId());
}
// verify that the process is actually finished
HistoryService historyService = processEngine.getHistoryService();
HistoricProcessInstance historicProcessInstance =
historyService.createHistoricProcessInstanceQuery().processInstanceId(procId).singleResult();
System.out.println("Process instance end time: " + historicProcessInstance.getEndTime());
}
}
I put the FinancialReportProcess.bpmn20.xml into the same folder as the java class. I also added all the jars that came with the activiti 5.6.14 package to my projects workspace.After the first start i experienced some "classDefNotFound" errors. I had to manually add .jars for ibatis-core (ibatis-core-3.0.jar), joda-time, h2 and apache commons. But i still get errors and cant execute this first simple 10 minute tutorial script because of the following error message:<quote>Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/ibatis/type/TypeReference at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at org.apache.ibatis.io.ClassLoaderWrapper.classForName(ClassLoaderWrapper.java:191) at org.apache.ibatis.io.ClassLoaderWrapper.classForName(ClassLoaderWrapper.java:91) at org.apache.ibatis.io.Resources.classForName(Resources.java:229) at org.apache.ibatis.builder.xml.XMLConfigBuilder.typeAliasesElement(XMLConfigBuilder.java:81) at org.apache.ibatis.builder.xml.XMLConfigBuilder.parseConfiguration(XMLConfigBuilder.java:61) at org.apache.ibatis.builder.xml.XMLConfigBuilder.parse(XMLConfigBuilder.java:55) at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.parseMybatisConfiguration(ProcessEngineConfigurationImpl.java:738) at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.initMybatisConfiguration(ProcessEngineConfigurationImpl.java:721) at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.initSqlSessionFactory(ProcessEngineConfigurationImpl.java:702) at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.init(ProcessEngineConfigurationImpl.java:436) at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.buildProcessEngine(ProcessEngineConfigurationImpl.java:408) at TenMinuteTutorial.main(TenMinuteTutorial.java:23)Caused by: java.lang.ClassNotFoundException: org.apache.ibatis.type.TypeReference at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) … 24 more</quote>I just don't get whats wrong and why i needed to add certain packages that are not being mentioned in the tutorial. Any ideas?
