[Export pdf to file and get file name back.]

Hello,

I am trying to export a report with over 10000 pages.

I am using  a virtualizer to avoid out of memory error.

I am currently trying to write the pdf export to a destination file in the 'JasperReportsPdfView' class.

But I am unable to return the filename as the exportReport() method returns void.

Moreover, the method also writes out the info into response.

Can someone please help me with a code snippet to achieve this?

thanks.

[Report with large number of pages rendered slowly.]

Hello,

I am using Jasper Report to render a report which has large data and runs over 1000 pages.

The report rendering is very slow and takes over 11 minutes(and counting) and uses up a lot of memory.

My system becomes unstable too.

Could anyone please help me how to speed up jasper report filling?

[Group expression to evaluate descending.]

Hello all,

I have a requirement. I am getting a dataset having data like :

Code_TYPE        CODE_NAME           DOLLARS

SITE                      BRAIN                           $2000

SIC                        LUNG                             $3000

SITE                      LIVER                             $1200

.....

I have a group which groups these and displays like :

SIC                        LUNG                             $3000   

SITE                      BRAIN                           $2000

SITE                      LIVER                             $1200

The group expression is $F(CODE_TYPE)

However, I want the SITE type codes to be displayed first. Like :

SITE                      BRAIN                           $2000

SITE                      LIVER                             $1200

SIC                        LUNG                             $3000   

How can I modify the group expression to group descendingly?

Thanks.

[How to embed the jasper report pdf in the browser]

Hello,

I am using Jasper Report in order to eliminate all crystal reports in our project.

I would like to know if it is possible to show the Jasper report(html) within the web page just like a crystal report is displayed.

Any help in this will be appreciated.

My requirement basically is : user goes to a parameter page, selects parameters, back end Java retrieves the data and then the user is sent to the report page.

Currently here I am able to throw the Jasper report out with an open save dialog.

How can I have the Jasper report to be displayed in the page?

Thanks,
