| How to modify, run and render a Report? [message #157065] |

I would like to modify a report prior to sending it the the
report engine to be rendered.
I therefore combined the example to use the DE API and the code
from ReportRunner to solve the task.
The problem i now face is that i cannot include the model.jar in
the classpath since this creates an error when using the report engine.
As i understand it an initalization of the plugin is neccessary for
the engine to be able to run (which is done by the framework).
How can I use the DesignEngine without putting it in the classpath -
or put it another way, how must I load the model plugin correctly?
Thanks for your help

Peter,
What version of BIRT are you using?
I did an example with 2.0.1.
I combined the two as well and all I had to do was add the Jars in the
Report Engine folder to my classpath. Attached is the code. Note that I
did not save to a file. I used Buffered Streams, which isn't memory
efficient. Pipes are probably better.

Peter,
The example I posted will not work it RC1a. It should work in RC2 when it
is available.
I am attaching an example of the executing a report that should work with
RC1a, but the DEAPI code is not in it.

Peter,
I am not certain this is the same problem. Your app if it is an ODA should
have a runtime reliance on ODA anyways. I just tried executing a report
using the REAPI with a flatfile datasource and didnt have to include
anything related to ODA at design time, just the libs in the RE lib
directory. All I had to do is make sure OSGI loaded up my plugins, by using
the factory to create the engine.
IPlatformContext context = new PlatformFileContext( );
Platform.startup( context );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
Try this with your example. Note this is 2.1 rc1a and make sure your ODA is
in the plugins directory. Let me know how it goes.

Jason, I tried the new version (RC2) and using the flatfile plugin now
works
when using the design engine and the report engine.
But my own plugin can no longer be found. When trying to run a report with
my own datasource it fails with the exception below.

From the OSGI-framework I first got the error that the MANIFEST.MF file for
the plugin could not be found. I then created the file with the following
content listed below.
Could you give me a hint on what the problem could be?
Thanks
