Hi,
I'm trying to implement the runtime engine into our company framework.
And now have the result of a report embedded into a JSP. The report
contains links to other reports, so called drill-down, but the links are
NOT displayed in my embedding. How do I set up the engine so it
generated the right links to the other reports? Do I have to use
IHTMLActionHandler or something like that and can you provide me with an
example? Thanks in advance.
Regards, Jan.

Well, I did use the example code for generating report from Java code,
so you can just view that code from the BIRT website, at least it used
to be there:
public void run(OutputStream outputStream) {
EngineConfig config = new EngineConfig();
config.setEngineHome(engineHome);
if (tempDir != null) {
config.setTempDir(tempDir);
}
String format = HTMLRenderOption.OUTPUT_FORMAT_HTML;
if(formatType.equalsIgnoreCase("PDF")) {
format = HTMLRenderOption.OUTPUT_FORMAT_PDF;
}
HTMLEmitterConfig hc = new HTMLEmitterConfig();
HTMLCompleteImageHandler imageHandler
= new HTMLCompleteImageHandler();
hc.setImageHandler(imageHandler);
config.setEmitterConfiguration(
format
, hc);
ReportEngine engine = new ReportEngine(config);
IReportRunnable report = null;
try {
report = engine.openReportDesign(input);
} catch (EngineException e) {
System.err.println("Report not found!\n");
engine.destroy();
return;
}
if (format != null) {
parseParams(engine, report, parameters);
IRunAndRenderTask task =
engine.createRunAndRenderTask(report);
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(format);
options.setOutputStream(outputStream);
options.setEmbeddable(embeddable);
task.setRenderOption(options);
task.setParameterValues(parameters);
// Run the report.
try {
task.run();
} catch (EngineException e1) {
System.err.println("Report run failed.\n");
System.err.println(e1.toString());
}
}
engine.destroy();
}
Good luck with the integration, it works fine here now:) Besides the
drill-down linking.
Regards, Jan.
