How forward from an actionListener
Hi,
How can i forward from an actionListener? I have an actionListener
where i get a values from selected row in dataTable and then put the
values of this row in a session variable, after this i need redirect
to another page where these values will be shown to the user.
This is possible?
Thanks for any help,
Rogério

Hi Rogerio, you can use the NavigationHandler, like this:
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext,
null, outcome);
You put in 'outcome' a value you have already defined in a
navigation-rule in the faces-config.xml. For your interest, the
arguments for the method handleNavigation are:
void handleNavigation(FacesContext context,
String fromAction,
String outcome);

Bruno

Buff, I was really puzzled as I had used that approach several times
successfully... :-) I thought that you were answering to me and not to
Rogerio's question. This is the kind of things that can happen when
your native language is not the english and you read mails in
diagonal....

That's true, however there is a very simple way to do navigation from
the action-listener ;)
Do it like that:
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().getNavigationHandler().handleNavigation(fc,
fromAction, outCome);

Re: How forward from an actionListener

No, it is not.
there is no return string from an action-listener.
what you can do is set both the action-listener and the action
parameters, and knowing that the action method is called after the
action-listener, you can do something with your backing bean to ensure
that in the action method you return the right string.
If it is always the same page you will be going to, you can just set a
fixed string in the action-parameter.

Martin

Re: OT: How do you intergrate a Jasper Report into a MYFaces app?
Posted by Graham Stark <gr...@virtual-worlds.biz>.
Well, I'm sure there are dozens of people on this list better at this
than I am, but I did get this to work so here goes:
In the jsp I have:
<af:commandButton
rendered="#{model.annualReportAvailable}"
actionListener="#{model.makeAccountsReport}"
returnListener="#{model.makeAccountsReport}"
text="Your annual report is available" />
(this is an Oracle ADF button, but it should be almost the same using
Myfaces).
Model is my model, declared in the usual ways. It contains an
isAnnualReportAvailable method, various things to fill up the report,
and makeAccountsReport method which looks like:
public void makeAccountsReport( ActionEvent event ){
try{
Reporter reporter = new Reporter();
// fill in your report here...
reporter.setStuff(....);
FacesContext context =
FacesContext.getCurrentInstance();
HttpServletResponse response =
(HttpServletResponse)
context.getExternalContext().getResponse();
response.setContentType(
"application/pdf");
response.setHeader(
"Content-disposition",
"attachment;filename=AnnualReport_"+
model.getYear()+".pdf" );
OutputStream out =
response.getOutputStream();
reporter.writeReport( out );
context.responseComplete();
} catch ( Exception e ){
logger.error( "getAccountsReport(): failed to write"+
" pdf to output with exception " + e );
}
}
You can try it here, if you like:
http://www.mazegreenyachts.com
(not quite finished, but getting there). The report should appear on the
main results page every fourth quarter. (Actually, the version here is
using Fop rather than Jasper Reports, but the principle is exactly the
same)
hope this helps

RE: OT: How do you intergrate a Jasper Report into a MYFaces app?
Posted by Dani Kenan <da...@netvision.net.il>.
Glen,
Leaving MyFaces out, do you know how to show it using a simple servlet/jsp
application?
If not, could you describe the use case and user interaction you want to use
for generating a sample report?

Graham,
This is great but would it be possible to see a bit more? I am completely in
the dark about how the report is added to the web application. What must
happen? what does the JSF page code look like? I can see how to generate the
report but how to I transfer that to the client machine? I am afraid I am a
bit of a newbie when it comes to report generation and printing.
Thanks
