Hi, I'm posting here because I can't find lot's of information about how to set up timers in jBPM. I've added a timer to my task : <timer name="waitForApproval" | duedate="1 minute" | transition="validee" > | <script> | System.out.println("Le valideur est trop lent : valid????e !!!"); | </script> | </timer> It seems timers need what you call a scheduler service. After some researches, I find out that I must add this to my web.xml : | <servlet> | <servlet-name>JbpmThreadsServlet</servlet-name> | <servlet-class>org.jbpm.web.JbpmThreadsServlet</servlet-class> | <load-on-startup>1</load-on-startup> | </servlet> | <servlet-mapping> | <servlet-name>JbpmThreadsServlet</servlet-name> | <url-pattern>/threads</url-pattern> | </servlet-mapping> | I did that, but I find an exception : java.lang.ClassNotFoundException: org.jbpm.web.JbpmThreadsServlet And surprise! There is no such class in my jbpm jar file. I took the last one from jbpm-installer-3.2.6.SP1.jar : jbpm-jpdl.jar On JarSearch, I found that the class is present only in version jbpm-3.1.4.jar and before. So what am I doing wrong, or what did I miss? Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223063#...
