You should create a actionform with all the incoming parameters and
whatever values that you might need to pass back.

Then in the action you can check for those values.
Say the ActionForm would contain a property called "category" and you
would have getter and setter for that. Then in the Action instead of
doing request.getParameter("category"); you would just do a
form.getCategory(); and also for outgoing values just create another
property for example if you have a collection that you want to pass to
the jsp page, say the jsp page wants to show a list of something.

You can then create a property in the form for that collection say
"coll" and then in the Action after getting the values from the
SessionEJB set them in the form. Then you can access them on the page
using the standard tags from struts.

The sessionEJB could return anything, depending on the method called. 
 From a Collection to a single value. The initial idea was to make 
getters for each value to be seen on the view.

We weren't planning on using ActionForms from the start. At the moment 
we're using URLs to pass parameters, like "" 
and getting the value of the parameter passed, in the Action with a 

I like your solution (use the ActionForm), could you provide an example 
of getting the category parameter from it and then add the result values

in the ActionForm?

Thanks in advance.
