JSP+Servlets+Activiti = error

[leandro1]

this from a java class works fine, but when you use on servlet the result is…. 

java.lang.NoClassDefFoundError: org/activiti/engine/ProcessEngines
   servlets.Hello.doPost(Hello.java:56)

This is the code:

Hi Leandro,

do you have process engine in your class path?
(I do not like idea to use process engine on JSP page)
