Integrate BIRT in a spring service

Hello !

After several searches (and hours) i cant figure out how integrate BIRT report engine in my spring service.

What I have :

- Spring service that use a BirtManager class to generate pdf
- BirtManager, a class to init report engine and run&render (+ start,stop Platform)

The Birt manager reference an absolute BIRT engine location.

All works nice but...

If the service is deployed elsewhere my machine the engine doesn't work any more, obviously...

How can I integrate the Birt Engine (absolute path?) in my service ?

Any help/suggestion is welcome.

Can you post the code you are using to startup the engine? Are you using a PlatformFileContext or a PlatformServletContext. PlatformFileContent looks for a hard location.

Hello Jason,

thank you for the fast answer.

I'm not using PlatformFileContext or PlatformServletContext,
I only set the Birt home to point ReportEngine path.

public void startReportEngine() throws DocumentGenerationException {
getRuntimeResource(); // DO NOTHING
if (reportEngine == null) {
try {
// create engine config
EngineConfig config = new EngineConfig();
config.setLogConfig(null, Level.SEVERE);
config.setBIRTHome(BIRT_ENGINE_LOCATION);
// start the paltform
Platform.startup(config);
// get the report factory
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
// create the report engine
reportEngine = factory.createReportEngine(config);
} catch (BirtException e) {

LOGGER.error("Unable to start the report engine!", e);
throw new DocumentGenerationException("Unable to start the report engine!");
}
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("Birt Report Engine started successfully.");
}
} else {
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("Birt Report Engine already started.");
}
}
}

The default is PlatformFileContext. If you have set BIRT_HOME to a hard location the framework should be starting up. What error are you getting?

I try to explain better:

I have a jar with inside a Spring service.
This service generate a pdf.
Uses Birt Report Engine localized in src/main/resources of the same project
In unittest all works fine.

When I deploy this jar on a server the report engine doesn't start,I think because report engine location is missing:
org.eclipse.birt.core.exception.BirtException: Cant startup the OSGI framework
at org.eclipse.birt.core.framework.Platform.startup(Platform.java:91)
BIRT 2.5.2

maybe is just a missing context.

You most likely need a PlatformServletContext:

Take a look at this blog that references other spring exmaples:
