Hi,
coming from the PHP world I am starting to get practice with Stripes.
And I wonder how to best communicate between JSP and my ActionBean. In
PHP I liked to use "smarty". There one just saves all the data the
template needs into a large HashMap und the template will work with this
map, after the lifetime of what was comparable to the ActionBean already
exceeded its lifetime.
I noticed that I can get the same behaviour with JSP by using
getContext().getRequest().setAttribute("name", someObject);
That works very well, but I doesn't feel like I am "supposed to do
this". Am I? Is this a suitable approach? Or are there good reasons to
keep hands away from this?
The other way is obviously to have some getter-methods on my ActionBean
that I call from the JSP file. That is what I used most of the time. But
sometime I want to calculate values for the JSP in my event handler.
Thus I have to save them in a property of the ActionBean and introduce a
getter method for them. That works well for small ActionBeans, but with
a rising number of event handlers within one action bean I easily loose
the overview which property I introduced for which event handler.
Another approach that I have seen is creating a POJO for each and every
jsp page with all properties for that JSP page. Then this object is
saved as a property of the actionBean and it is worked with from JSP
(additionally this may save a little memory because only the properties
that are actually needed by the current JSP need to be allocated).
What would you say is "best practice" and why?
Thank you,
Thomas
