<div class="jive-rendered-content"><p>I think the jBPM Develpers Guide is not correct in 2.1.2 Business Calendar:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code"> For example:
public class CustomBusinessCalendar implements BusinessCalendar {
 
  public Date add(Date date, String duration) {
    if ("my next birthday".equals(duration)) {
      GregorianCalendar gregorianCalendar = new GregorianCalendar();
      gregorianCalendar.set(Calendar.MONTH, Calendar.JULY);
      gregorianCalendar.set(Calendar.DAY_OF_MONTH, 21);
      return gregorianCalendar.getTime();
    }
    return null;
  }
}    
To configure the jBPM engine to use this custom business calendar, just add      the following line to your jbpm.cfg.xml:
<process-engine-context>
    <object  class="org.jbpm.test.custombusinesscalendarimpl.CustomBusinessCalendar"
/>
</process-engine-context>  
Take a look at the      
org.jbpm.test.custombusinesscalendarimpl.CustomBusinessCalendarImplTest for more information.
