Why would you want to call an Action class directly from a JSP (outside a

RE: Call action from JSP
I don't use form because I don't need to submit any data. The action will
perform some logic against query string in request and data in session, and
forward wither to a success page or a failure page.
I could put this logic directly in JSP rather than in an action, but I
don't want so many Java code in JSP.

RE: Call action from JSP
You don't need to do it this way - you map the JSP to an Action class in
struts-config.xml and Struts will automatically send the data to the class
when the request URL changes.

RE: Call action from JSP
hmmm...why not check your condition and perform this logic in an action before you
even forward to the JSP in the first place?
b.t.w., you can always issue a response.sendRedirect( URL ) in the JSP scriplet, and
give it the URL-mapping for the action you wish to redirect to. I don't think that
doing this is a great idea, however. :)
peace,
Joe

RE: Call action from JSP
The JSP is an index.jsp and condition has to be check there.
If I use response.sendRedirect(URL) in the JSP scriplet, it seems that a
new request is created during redirect. Is there a simple way to keep the
previous request rather than create a new one?

RE: Call action from JSP
This was sorta mentioned before, but...why not have and index.do instead of
an index.jsp? Does index.jsp show something to the user or does it just
do some logic and then call the server?
If it does the latter, make it a .do

RE: Call action from JSP
I am new to struts and I don't know if this is of any use or if it is even
right, but when I wanted to call an Action when the user clicked a link I
used something like (no forms involved):
pBuild Database: a href=1-5-1_BuildDatabaseAction.doButton/a/p
and in my struts-config.xml had something like:
action
path=/1-5-1_BuildDatabaseAction
type=com.myapp.view.DBAdminClient
name=
input=/1-5_SAMainPage.jsp
forward name=db_create_successpath=/success.html/
forward name=db_create_failed path=/fail.html/
/action
I left name= because I wasn't doing anything with a form, just responding
to a user clicking on a link. I welcome comments letting me know if this is
the right way to be doing this or (rather more likely) that I am clueless
and that there is some other struts mechanism I should be using to handle
getting access to the action mappings when no forms are involved.
Thanks,
- Jim

RE: Call action from JSP
I see nothing wrong with what you are doing. You don't even need the name
= in the xml. You might want to look at html:link in case you need to
do anything more with maintaining session, etc.

Not that I know of. You can put the request parameters you would like to pass on in
the query string of the URL you give to response.sendRedirect though.

This is fine. Just leave out both the name and input attributes, since
neither apply when there is not an ActionForm.

Re: Call action from JSP
Without Struts (sometimes even with it), I'd use either of the following
in a JSP:
jsp:forward page=urlSpec/
or
jsp:forward page=urlSpec
jsp:param name=name value=value/
...
/jsp:forward
For servlet code, I'd probably go with
RequestDispatcher.forward(ServletRequest request, ServletResponse
response), using ServletRequest.getRequestDispatcher(String path) to get
the dispatcher.
