Seems you have no current jbpm context - it should be initially created.

In web-application example (you can find it in jbpm sources) this is done by org.jbpm.web.JbpmContextFilter - just configure your web-application to use it in your web.xml:

<filter>
 <filter-name>JbpmContextFilter</filter-name>
 <filter-class>org.jbpm.web.JbpmContextFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>AuthenticationFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

Hope it helps!
