      I hope i am writing this question into the correct place.
      I am trying to make an application with JBoss. I have to establish connection with MYSQL database.I found some articles about how to connect to MYSQL database and i believe that i did everything correct.
      But this error message is shown on the web browser after i ran the program.

      Exception :
      javax.servlet.ServletException : Cannot get value for expression '#{homeBean.taskInstances}'
      javax.faces.webapp.FacesServlet.service(FacesServlet.java:109)
      org.jbpm.webapp.filter.AuthenticationFilter.doFilter(AuthenticationFilter.java:55)
