Hi all,

I started to try out Birt in favor of Itext.

I made a report and connected it to my running hsqldb

Connection test was: OK

Now i made a test report, just printing some lines from a table in my db.

Te result was wat I expected and was the same as in the preview !

But i still get some sever exception when i run my code :

engine = factory.createReportEngine(config);

IReportRunnable design = null;
design = engine
.openReportDesign("src/test/java/birt/reports/secondTry.rptdesign ");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);

PDFRenderOption options = new PDFRenderOption();
options
.setOutputFileName("c:/Users/javadev/Desktop/tempbirt/test2.pdf ");

options.setOutputFormat("pdf");

task.setRenderOption(options);
task.run();
task.close();
engine.destroy();
} catch (Exception ex) {
System.out.println("Error in executeReport : ");
ex.printStackTrace();
} finally {
Platform.shutdown();
}
}

You might notice it's the example code from the wiki.

So i don't know what i'm doing wrong, since there were no errors making the preview and the result is fine, because i get a pdf file with the data :s

Could someone please help.

This error:
DriverClassLoader failed to load class: org.hsqldb.jdbcDriver

indicates that the driver jar is not in the
birt-runtime-2_5_1\ReportEngine\plugins\org.eclipse.birt.rep ort.data.oda.jdbc_2.5.1.v20090821\drivers

directory. Can you copy it there? You can also alter your code to pass in the path like:

config.getAppContext().put("OdaJDBCDriverClassPath", "c:/birt/mysql/mysql-connector-java-5.0.4-bin.jar");

Thank you Jason. I also encountered the same problem but using Oracle 10g XE (for learning). I had added the following to my classpath when running my stand alone Java app:

C:\software\birtruntime\birt-runtime-2_6_2\ReportEngine\lib\ *.jar

C:\software\oracle10gExpressEdition\app\oracle\product\10.2. 0\server\jdbc\lib\ojdbc14.jar

My stand alone app did generate the pdf file but got the same error:

DriverClassLoader failed to load class: oracle.jdbc.OracleDriver

I then proceeded to add the following to the java code, as you suggested in your post:

config.getAppContext().put("OdaJDBCDriverClassPath", " C:\\software\\oracle10gExpressEdition\\app\\oracle\\product\ \10.2.0\\server\\jdbc\\lib\\ojdbc14.jar ");

The errors are gone too!

Thanks again!

If you are using the RE API add it when you create the engine config.

eg

EngineConfig config = new EngineConfig();
config.getAppContext()......

If you are using the viewer you can add it to either the beforeFactory
script or the beforeOpen of the datasource. Just put it in like:

reportContext.getAppContext().put("OdaJDBCDriverClassPath",
"C:\\software\\oracle10gExpressEdition\\app\\oracle\\product\
\10.2.0\\server\\jdbc\\lib\\ojdbc14.jar");
