Integration in JBoss app possible? [message #249077]

Is it possible to integrate the BIRT Engine API into an application
deployed on JBoss?

I have installed the BIRT 2.2.0 "platform" files (copied from the BIRT
Viewer) in a directory outside of a JBoss controlled directory. I
configured IRT following:

http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.p hp

My code:

private static EngineConfig config = null;

public void create(String filepath, OutputStream outputStream, String
format, Map<String, String> params){
try{
if(config == null) {
config = new EngineConfig();
config.setEngineHome("C:\\var\\itsolut\\birt\\platform");
// config.setEngineHome("/var/itsolut/birt/platform");
config.setLogConfig(".", Level.FINEST);

IPlatformContext context = new PlatformFileContext(config);

config.setPlatformContext(context);

try {
Platform.startup(config);
}
catch (BirtException e) {
throw new RuntimeException("Could not start the platform",
e);
}
}

IReportEngineFactory factory = (IReportEngineFactory)
Platform.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
IReportEngine engine = factory.createReportEngine( config );
engine.changeLogLevel( Level.WARNING );

InputStream stream = new FileInputStream(filepath);

IReportRunnable design = engine.openReportDesign(stream);

// here is where the exception (below) is thrown

</snip>

I am getting the following exception:

Chris,

Can you try to deploy the viewer as a test?
Take a look at the JBoss notes here
http://www.eclipse.org/birt/phoenix/deploy/viewerSetup.php

Jason,

Thanks for the reply.

I didn't try to deploy the viewer; but I did get the BIRT Engine to run in
my application so I can generate reports (only tried the PDF version for
now).

When I deployed just on Tomcat, I had to include 3 jars in my app:
coreapi.jar
engineapi.jar
modelapi.jar

In addition to these three, JBOSS ear files need two more files:
com.ibm.icu.jar
js.jar

Once I included these in the ear (not the war contained in the ear)
proper, everything now works.

Altough, I'm not sure why I need these two additional jars? I would have
thought the classes that need these jars would be in the platform only and
accessed via the OSGI mechanism used to deploy BIRT.

Chris....

BIRT makes use of all the jars in the ReportEngine/lib directory.
For example js.jar is used for scripting in BIRT.

ok - that makes sense. I was hoping that the number of libraries that I
had to include directly in my application would be smaller. Right now it
looks like it is going to come out to 9MB.

I was hoping more of those would have been included in the "platform"
directory which is a 1 time upload and configuration per JBoss instance
whereas the other libraries must be included in every application.

Thanks for the info.
