to point to a Java class that implements the DecisionHandler interface.</SPAN><BR /><SPAN>The decide() method of the handler class should performs the logic it needs to and then it should returns the name of the transition to take.</SPAN><BR /><BR /><SPAN>I have added the jar file of my java class at ..\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib&nbsp;
