BPMN sample error in eclipse activiti

Question

I was following activiti user guide http://www.activiti.org/userguide/#demo.setup.one.minute.version to install activiti and create the sample vacationrequest bpmn project. When I run the project I keep getting this error regarding process engine creation.

exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at org.activiti.engine.ProcessEngines.<clinit>(ProcessEngines.java:63)
    at vacation.resources.test.main(test.java:15)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
    at java.net.URLClassLoader$1.run(URLClassLoader.java:372)
    at java.net.URLClassLoader$1.run(URLClassLoader.java:361)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 2 more

This is my test.java class

package vacation.resources;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;

public class test {

    public static void main(String[] args) {
        // TODO Auto-generated method stub


        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        RepositoryService repositoryService = processEngine.getRepositoryService();
        repositoryService.createDeployment()
          .addClasspathResource("VacationRequest.bpmn20.xml")
          .deploy();

    //  Log.info("Number of process definitions: " + repositoryService.createProcessDefinitionQuery().count());
            }



}

and this is my activiti.cfg.xml file

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd">

  <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration">
    <property name="jdbcUrl" value="jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000" />
    <property name="jdbcDriver" value="org.h2.Driver" />
    <property name="jdbcUsername" value="sa" />
    <property name="jdbcPassword" value="" />
  </bean>

</beans>

I tried other options than getDefaultProcessEngine() but they all ended up with the an error.

Does your project use Maven or something else for dependency management? Looks like your project is missing logger implementation like log4j, logback, ...

Try add to project:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.10</version>
</dependency>
