Hello Florin thank you very much for answering so fast, but problem I'm
having is in a Java class action, there es where I cannot access the site
context.
Precisely I'm now trying to use java classes for actions, I'm not trying to
migrate all the application that previously used beanshell actions to this
new approach but I want new things in pure java.
What I don't understand is that asymmetry between java class based action
and script based ones. I'm not saying Jpublish is a bad thing, i've been
using it from years but nobody and nothing is perfect.
In fact what I tried to say is that java class based actions have nothing t=
o
do at start up if they can not access the site context, because where could
they put any object created?
My intention was to mention a quick and backward compatible fix
(StartupAction interface) that I have no problem to implement, the same
problem may be occurring in Shutdown actions so there may be a better name
:).
Certainly I can fix that in my own Application by calling a StartupAction
from a generic BeanShell kind of adapter where the action class is a
parameter of the beanshell adapter script.
my proposal is to define a new interface:
public interface StartupAction extends Action{
public void setSiteContext(SiteContext context);
}
And in the part of the code where the action is found (in findAction() when
handling start up actions)
if (action instanceof StartupAction)
((StartupAction)action).setSiteContext(siteContext);
or something like this.
Best regards and thanks again
