Integrating Birt Reports into OpenJacob is quite straightforward but note that (at the time of this writing) you need Birt Version 2.5 !

1. When creating the report’s datasource you have to use the same name you use in your jACOB application. Otherwise jACOB will not be able to use your Report.
2. Create your report and specify the required parameters.
3. When having finished your report, upload the .rptdesign file to a document field in your application. (e.g. a config table)
4. The following code opens the report, hands over a parameter and returns a .pdf

	BirtReport rpt = new BirtReport(cnfrec.getDocumentValue("report"));
	rpt.setParameterValue("mypar", currentRecord.getStringValue("pkey"));
	byte[] barr = rpt.createPDF();
	context.createDocumentDialog(null, "doc.pdf", barr).show();

For some reason it may happen in Ubuntu Lucid (10.04) that your USB storage devices aren’t detected anymore.

The indeed _very_ strange solution is to turn off LEGACY FLOPPY SUPPORT in the BIOS setup. If you don’t have such a setting (i.e like my Dell Precision T3400) and don’t have any floppy drive either then try deactivating everything that refers to floppy drives in the BIOS setup.
