yes, i read the documentation for that before posting here too. it says to "simply" drop in the struts2-spring-plugin-<version>.jar. i already have that in /WEB-INF/lib. however, towards the end of the document, they are referencing how to initialize Actions from spring using struts.xml and applicationContext.xml. since i am using Annotations and the conventions plugin, i don't think this is what i am looking for. currently, my struts.xml file is 3 lines only! (minus the DOCTYPE lines).
there are little but significant differences in how a struts2 based application behaves using the convention plugin (as opposed to using the traditional struts.xml file). i am committed to using the convention plugin + annotations and to avoid as much as possible configurations in struts.xml. if there is an example of how to get all this working (struts2 + convention + annotations + spring), i would be most pleased. thanks.
