在网上找了半天,都没找到一个完整的jbpm会签例子,哎没办法新手,等贵人指点一下,再整不出来就扫地出门了.

哎没办法jbpm新手,等贵人指点一下,再整不出来就扫地出门了.
照网上给的这个例子(http://www.javaeye.com/topic/125297)做了半天还是没解决问题.
第三段代码没给出来,自己出不会写.
异常如下:
couldn't parse set field 'actor' to value '<actor>#{reviewer}</actor>' [org.jbpm.instantiation.FieldInstantiator] - 6894438 2009-03-01 12:32:05,656 ERROR
