I have tried adding httpclient-4.3.3.jar to the buildpath as well as commons-io-2.5.jar but neither has fixed the issue, I have checked documentation but doesn't say I need any other libraries to run Unirest

BIRT : How to generate and save a report in PDF format using RE API

I am working on a project to generate BIRT reports in PDF format. The application is not meant to be a web application. I tried to follow the Report Engine API example on this link http://wiki.eclipse.org/Simple_Execute_(BIRT)_2.1 but I get an error when I run (Run as -> Java Application) the code. My code is as below.
My code is as follows:
package birt.classicmodels.offices;
import java.util.logging.Level;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.EngineException;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportEngineFactory;
import org.eclipse.birt.report.engine.api.IReportRunnable;
import org.eclipse.birt.report.engine.api.IRunAndRenderTask;
import org.eclipse.birt.report.engine.api.PDFRenderOption;
public class ExecuteReport {
public static void main(String[] args) {
ExecuteReport er = new ExecuteReport();
try {
er.executeReport();
} catch(Exception ex) {
System.out.println(ex.toString());
}
}
public void executeReport() throws EngineException {
IReportEngine engine = null;
EngineConfig config = null;
IReportEngineFactory factory = null;
Object factoryObj = null;
try {
config = new EngineConfig();
config.setBIRTHome("C:\\birt-runtime-4.6.0-20160607\\ReportEngine");
config.setLogConfig("C:\\temp\\test", Level.FINEST);
Platform.startup(config);
factoryObj = Platform.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
factory = (IReportEngineFactory) factoryObj;
engine = factory.createReportEngine(config);
// Open the report design
IReportRunnable design = null;
String designPath = "C:\\birt-runtime-4.6.0-20160607\\ReportEngine\\samples\\hello_world.rptdesign";
design = engine.openReportDesign(designPath);
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
PDFRenderOption PDF_OPTIONS = new PDFRenderOption();
PDF_OPTIONS.setOutputFileName("C:\\temp\\test.pdf");
PDF_OPTIONS.setOutputFormat("pdf");
task.setRenderOption(PDF_OPTIONS);
task.run();
task.close();
engine.destroy();
} catch(final Exception ex) {
ex.printStackTrace();
} finally {
Platform.shutdown();
}
}
}
SETUP:
I installed the BIRT designer using the complete BIRT designer download.
I added all the .jars under the libs folder of the BIRT runtime folder to my build path.
The main method was not part of the example I added it with the intention of getting the report saved to my file system.
The design template I'm referencing is the design example that comes with the BIRT engine.
ISSUES:
When I run the code (Run as -> Java Application) I get the following errors:
A pop up dialog with the message:
Java Virtual Machine Launcher
Error: A JNI error has occured, please check your installation and try again
After I click OK on the message dialog, the console is populated with the following error:

I think you are missing following dependency

<groupId>org.eclipse.birt.runtime</groupId>
<artifactId>org.eclipse.birt.runtime</artifactId>
<version>4.6.0-20160607</version>

i got dis code from https://github.com/sagioto/LipReading/blob/master/lipreading-core/src/main/java/edu/lipreading/WebFeatureExtractor.java..
can anyone help me plz..

java.lang.VerifyError can happen if you're running against a different version of a library than the code was compiled against.
Looking in the github repository, I see the files are dated 25 April 2013. Apparently, Jetty has received an update during these last 10 months. Find the version of Jetty that was current on that date and try again.

You may need to add the latest release of this library (ConcurrentLinkedHashMap for Java):
http://concurrentlinkedhashmap.googlecode.com/files/concurrentlinkedhashmap-lru-1.3.1.jar

The code you shared works fine. I think the problem is with your import statements. They should be like this:
import java.util.HashMap;
import java.util.Map;
import org.neo4j.cypher.javacompat.ExecutionEngine;
import org.neo4j.cypher.javacompat.ExecutionResult;
import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Transaction;
import org.neo4j.kernel.EmbeddedGraphDatabase;

It looks like a library error. Perhaps you have imported the wrong version of something?
Just in case, I should point out that you are meant to use the GDB factory for building an embedded instance:
graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);
Not sure that it will make any difference.
