Take a look at the JavaScript API (JSAPI). This will allow you to seemlessly embed the Actuate BIRT Viewer into your application. There are documented examples that you can browse to within the Information Console located in /Public/JSAPI Examples.

Additionally here is a link to the documentation:

thank you for your reply,

I work with a java application and I use the java client axis to communicate with my server,
I can download the report from the server to download class and stores it on my local machine but I can not display it in my application,
thank you for your help

Robs suggestion of using the JSAPI is really going to be the easiest and prefered way to go. But if your not using a web application, then you will need to use IDAPI calls directly (which it sounds like you are). You will need to make 2 calls, ExecuteReport or SubmitJob, which will run a report on iSErver, and SelectPage, which will make iServer render to an output format. With select page, you specify what type you want it rendered in (HTML, PDF, WORD, etc), and you will get back a binary string that you will need to decode and display.

Hello johnw ,

thank you for your answer is exactly what I did, but I'm running the report with the class ExecuteReport, and I get the result with download class and I can save back to disk, but displays the result in my java application that's what the problem wonder if you could explain to me how I can use the class SelectPage thank you in advance

johnw

DownloadReport will not download the final output, just the rptdocument or binary ERD report. SelectPage will take those binary reports and render them out. I posted an example here: http://www.birt-exchange.org/org/forum/index.php/topic/23359-how-to-get-report-content-via-actuate-web-services/page__fromsearch__1

hello Johnw, 
thank you for your answer, but I always problem to use the code that you have spent, 
Here's the code I execute the report for, unwanted and displays the report rated client.

and even a small thing is that I can not identify the "RunReportsAC10", 
thank you again.

hello, 
Here is the error that generates this code for me on this line bold: 
public ActuateSoapBindingStub proxy; 
GetPageCountResponse pageCount = proxy.getPageCount(getPageCount);

Do you have the Server Integration Technology package? This package includes several examples, including one to download report pages.

Here is the package:
http://www.birt-exchange.org/org/wiki/index.php?title=Server_Integration_Technology

Once installed, look in the following directory (assuming a default install)
C:\Program Files (x86)\Actuate11\ServerIntTech\Web Services\Examples\Axis Client\Source

johnw

Sorry, RunReportsAC10 is the main class. The WriteOutput method is literally just using an Output Stream (in the case of this example, it is outputting to a PDF file), so it is just wrapping a FileOutputStream and using the byte array returned from SelectPage.

mama

hello everyone,
thank you for your answer, is what you can tell me if I have an error in my code the above,because it generate me an error that posted above,It gives me this error line "GetPageCountResponse pageCount = proxy.getPageCount(getPageCount);"
I'm really stuck on this topic,help me please

mama

Hello johnw
if you like it ,if you can send me the comple code to use the SelectPage class, thank you in advance
