taken those 3 into account, I think you really do need serious help. Not
being funny, but usually people either working with other experienced
developers or simply with a few years of Java and some EJB exposure should
be endevouring with such a task.
> 1) Is this the appropriate way to call EJBS (in an action class)??
yes, it's fine to call EJB's from the action class.
> 2) How do I get what is returned from the EJB back into my actionform
bean?
you (presumably) will get back an object/collection of data back from the
EJB. you can parse it and populatev the form with it/add to the request -
then pull it out in the jsp with the struts cust tags.

see above. To reiterate, put it an Collection (ArrayList for example) or in
a custom Object (JavaBean.. not Enterprise Java Bean!!)

as far as I know not of Struts/EJB. Weblogic comes with a good load of
examples, so does the Struts install.
