RF + JasperReports

[elf]

Hi
I am trying to run simple JasperReport.
When I saved it into file everything works fine.
But, I want browser propose user to download report.

There is modalPanel, there is HtmlAjaxCommandButton on panel.
There is action attached to the button.

It is my code:

ServletOutputStream out = ((HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse()).getOutputStream()

byte[] bytes = null;
((HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse()).setContentType("application/pdf");

JasperReport rep = getJasperReportObject(md);
if (rep == null)
 return "";

bytes = JasperRunManager.runReportToPdf(rep, new HashMap(), new JREmptyDataSource());
out.write(bytes, 0, bytes.length);

((HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse()).setContentLength(bytes.length);

((HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse()).addHeader("Content-Disposition", "attachment; filename=" + md.getClassName() + ".pdf");

out.flush();
out.close();

FacesContext.getCurrentInstance().getExternalContext().redirect(RichHelper.getRequest().getContextPath() + PORTAL_PAGE);
FacesContext.getCurrentInstance().responseComplete();

Page refreshed, but no request to download file.
I am new to RF and to JasperReport, please help me. What I am doing wrong.

Hello,

AJAX requests are invisible to end-user, so that's the reason why no dialog appears. Also please take a look to recently created issue: https://jira.jboss.org/jira/browse/RF-7019

In this case is the refreshing of whole page the good solution ?
May be it will be better to open new clear page and from there propose to download file ? In case of yes coluld you please drop me a piece of code how I can do it ? Click on ajax button, open new page and call action from new page ?
Or may be there is another good solution for this ?

Use h:commandButton to initiate download request or use a4j:commandButton and redirect to the file (e.g. redirect to servlet that will output the file)

nbelaevski, thank you for help.
I think the best solution for me will be to open new page by clicking on the ajax button and then propose user to download file. I want existing page stay as is.
Please drop me the piece of code how I can open new page by clicking on ajax button and fire action from this new page.
Thanks in advance.

How about using rich:modalPanel component instead of creating new page?

[elf]

My ajax button is already on modalPanel (I wrote in first post).
If it is possible to download file from modalPanel, so may be there is mistake in my code above ?
If it is not possible to download file using ajax button on modalPanel, I would prefer to open new page and download file from there.
Thank you.

Use h:commandButton and "target" attribute to open new page.

[elf]

nbelaevski, please post the piece of code. I don't understand how I can do that.
Thanks in advance.

[nbelaevski]

<h:commandButton target="_blank">...</h:commandButton>

will open new popup window as a result of button action execution.

[elf]

nbelaevski, I can not find attribute TARGET in TLD.
Could you please point me where I can find it ?

P.S. I have been trying to open new page using javax.faces.component.html.HtmlCommandButtom.

[nbelaevski]

You are right, and I was wrong - very sorry for that. There's no such supported attribute at h:commandButton, only h:commandLink supports "target".
