Getting total #pages back to the program

2003-07-02 19:25

Is there any way for the program to get the total number of pages printed when it generates a report? I need to store these statistics in a database for every report run.

Thanks.

You can with a trick. Add to your parameters map

passed to the fill method of jasper an Hashmap like this...

 

...

 

HashMap mymap = new HashMap();

parameters.put("MyHashMap",mymap);

 

....

 

Add in your report a parameter of type Object to recive this parameter (and name it MyHashMap).

Then create a variable of type Object with an expression like:

 

((java.util.HashMap)$P{MyHashMap}).put("MyReturnVal", $V{PAGE_NUMBER})

 

and resetType = "Report".

 

In this way, during report filling, jasperreports will put the number or report printed in you hashmap.

When the report is produced, you can retrive the number of page printed looking the value of...

 

(Integer)mymap.get("MyReturnVal");

 

Enjoy.

this method didn't work, the value returned is always "1" !
