Hi,
As struts2 comes along with spring integration with
struts2-spring-plugin-2.0.11.jar,after starting the tomcat server its unable
to load that jar and getting an exception as:
SEVERE: Exception starting filter struts2
Unable to load bean: type:com.opensymphony.xwork2.ObjectFactory

What is the reason for this?I have checked whether I have loaded same jar
double times,but tht's not tht problem?what might b the reason?Does any body
came across this one?
Also,the link:
http://www.roseindia.net/struts/hibernate-spring/integrate.shtml helps in
integrating struts1+hibernate+springs.But, since I would like to work with
struts2+Hibernate+Spring,what modifications I have to do to satisfy my
requirement?Since ation forms concept is not there in struts2...!!!
Thanks.
