A common question that comes up in the newsgroups for BIRT is how to access the total page count during render time. You would think this is an easy question to answer, however it has proven more difficult than originally thought. There is an Auto-Text item already in BIRT that will display the total page count, but none of its properties are accessible publicly.
Fortunately, there is a workaround. To get access to the total page count, you need to get access to the Report Document Reader created after the Run Task has completed. This is stored in the application context, but in a private field. So how do we get access to the report document? By using Java Reflection. Below is an example of how to get access to the Report Document Reader stored in the app context. This needs to be put into the beforeFactory event, which means it is only available at Render Time.
var rciClass = reportContext.getClass();
var fieldFromScript = rciClass.getDeclaredField("context");
fieldFromScript.setAccessible(true);
var execContext = fieldFromScript.get(reportContext);
// Now, we have the exeuctionContext. We can get the currently rendering
// report documents location
var doc = execContext.getReportDocument();
if (doc != null) {
var pageCount = doc. getPageCount();
reportContext.setGlobalVariable("totalPageCount", pageCount);
}
So now you can use the totalPageCount variable anywhere in the Render phase. So keep in mind, you can’t add this to a report because the report element are created during run time, this is only used to affect Render operations. You could create a report item extension to display it, and to demonstrate that, I dropped a chart since charts are created at render time. The chart will display the text “Page Count” on the X Axis, and the bars will go up to the actual page count.

That will only work if you are doing a RunAndRender operation. If you are doing Run then Render to build your report, you should use
setPersistentGlobalVariable
Probably best to always use persistent unless there is a specific reason for wanting different behavior in render then run.
It will work with either the Run And Render or the Run Then Render methods. The global variable is set in the beforeRender event, so it will be available throughout the entire render phase regardless of which task is used. If it were being set in the beforeFactory event, this would be true, but the report document reader is not instantiated during the run phase. It was tested with both.
can't use java reflection with birt 2.2.2 or 2.3.2. Is there something special to do ?
thanks
Nope. The above example was tested with BIRT 2.3.2, 2.3.2.2, and 2.5.
I confirm with 2.5, this solution works only in Run + Render. ReportDocument exists only after a IRunTask.
public class TSCReportEventAdapter extends ReportEventAdapter {
public void initialize(IReportContext context) throws ScriptException {
super.initialize(context);
}
private ExecutionContext execContext;
@SuppressWarnings("unchecked")
public void beforeRender(IReportContext context) throws ScriptException {
super.beforeRender(context);
Class rciClass = context.getClass();
Field contextField;
try {
contextField = rciClass.getDeclaredField("context");
contextField.setAccessible(true);
execContext = (ExecutionContext) contextField
.get(context);
// Now, we have the exeuctionContext. We can get the currently rendering
// report documents location
IReportDocument doc = execContext.getReportDocument();
if (doc != null) {
long pageCount = doc.getPageCount();
context.setGlobalVariable("totalPageCount", String.valueOf(pageCount));
}
} catch (SecurityException e) {
throw new RuntimeException(e);
} catch (NoSuchFieldException e) {
throw new RuntimeException(e);
} catch (IllegalArgumentException e) {
throw new RuntimeException(e);
} catch (IllegalAccessException e) {
throw new RuntimeException(e);
}
}
}
Is this working for birt 2.1.2???
I need page re-numbering feature for my report, since I dont want my 1st page have a page number on it. But the page number and the total page must exist for the next page and the rest.
Therefor if I have 3 pages, page number 1 exist in 2nd page and the total page should be 2 not 3.
How can I make this??
I am not sure that is possible in BIRT 2.1.2. In later versions, it is possible to just create a simple script that will hide the page number by putting something in the onRender event. So it would be something like:
onRender:
//pageNumber is a variable available at render time
if (pageNumber == 1)
{
//not the exact syntax
this.getStyle().hidden = true;
}
Then you would create a simple master page footer with pageNumber - 1;
