NullPointerException Platform.createFactoryObject [message #778328]

Eclipse Java EE IDE for Web Developers.
Version: Indigo Service Release 1
Build id: 20110916-0149
Birt 3.7.1

I've got java.lang.NullPointerException on:

  engine = factory.createReportEngine( config );
//...and then second one at line:
 design = engine.openReportDesign("C:/Users/ms/Libs/BIRT/birt-runtime-3_7_1/ReportEngine/samples/hello_world.rptdesign");

I believe it's connected with:

IReportEngineFactory factory = (IReportEngineFactory) Platform
    .createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY ); //

I've commented

//  Platform.startup( config );

but it didn't help.
any ideas, please?

Leave the Platform.startup. Are you setting a birt home? If so remove
it. 3.7.1 does not use this variable.

Ok, I've found Your solution for that issue - I havent't linked all jars from Engine folder. I cannot give a link to that topic so I'll just said thanks a lot!

Do you have all the libs from the reportengine/lib directory in your
classpath? How are you running this? As a simple Java app?

I also have same problem.
I am using Linux-mint
I have set BIRT_HOME=/home/developer/Birt/birt-runtime-3_7_0/ReportEngine

public File generateReport(
final Map<String, String> reportParameters,
final int reportId, final String outputFormat) {
IReportRunnable design = null;
try {
if(null!=dao) {
design = reportEngine.openReportDesign(
reportDesignFolderResolver.getFolder().getAbsolutePath()+
File.separatorChar +
dao.get((long)reportId).getName());
} else {
return null;
}
}catch (Exception e) {
logger.error(e.getMessage(),e);

}
////..............///
return new File(outputFile);
}

I got this exception,

With 3.7 do not set BIRT_HOME. Just add the jars to your classpath and
do a platform startup. In 3.7.2 we will most likely offer a POJO
runtime and an OSGi runtime to allow you to choose the way you want to
run BIRT.

Thanks for the quick reply. I still have a few more doubts.
Please help me resolve them. I have been struggling with them for a while now.

On Linux-I added all jars in jvm/lib/ext folder it works as expected in eclipse, but if I run this through maven it gives same error again. I have set CLASSPATH=BIRT_HOME\lib\*.jar

and in windows-by adding jar's in classpath it neither works in eclipse nor in maven.

on my machine (windows) without adding jars in classpath code is working in eclipse as well with maven, I have set BIRT_HOME=E:\Programs\birt-runtime-3_7_0\ReportEngine only.
same I am trying on another windows machine gives same error.

What is platform startup?

Just a brief about how we installed BIRT.
We installed BIRT from Eclipse -> Install new software from the url download.eclipse.org/releases/galileo

then I downloaded the BIRT runtime 3.7.0 and copied this jar files in jvm/lib/ext

Please help me resolve the issue.

I would not copy the birt jars to jvm/lib/ext. Also with 3.7 runtime
download do not set a birt home. Just add the jars from the
reportengine/lib directory to the classpath.

Thanks for the response,
I copied all jars in classpath, it works in eclipse. Though my ultimate goal is to make it work in maven. I am not able to find maven dependency for birt report.
Please help me to resolve this. Also if you could tell me the link from where I can download all the dependencies.

Hi

I am new to BIRT. I am using BIRT 4.2

I am facing similar problem. I have a maven project. My BIRT dependency looks like this:

<dependency>
	<groupId>org.eclipse.birt.runtime</groupId>
	<artifactId>org.eclipse.birt.runtime</artifactId>
	<version>4.2.0</version>
</dependency>

And when I run my application through eclipse, it works fine.

But when I creat a jar with dependencies using maven-assembly-plugin and try to run it. The createFactoryObject returns null.

Any help ...?

Thanks
