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
