Thank you very much for your help? In fact, yesterday I have solved the problem?Of course, new problems out? I currently available form components.However, components of images and javascript have something wrong. In HTML code I saw /jbpm/faces/myFacesExtensionResource/calendar.HtmlCalendarRenderer/11302665/images/calendar.gif The URL object is not created.I have just started to learn the JSF, so I do not know why this happens Yes, this is not an JBPM's issue?I hope to get your suggestions.
