I made a report template with a bar chart, by Eclipse 3.0.1 and
birt-report-framework 2.0.1 . It shows no problem when rendered in
Eclipse's preview window or when deployed to the Web Viewer Example of
birt-runtime-2.0.1 on JBoss 4.0.3.
But when I try to use the Report Engine API (also from birt-runtime-2.0.1)
to write my own webapp, I could generate the report but could not generate
the chart image in it. No Exception is thrown in the server log.
Did I missed some methods to call?
Below is my Servlet code:
OutputStream out = resp.getOutputStream();
String reportName = "barchart.rptdesign";
try
{
EngineConfig config = new EngineConfig();
config.setEngineHome(this.getServletContext().getRealPath("/WEB-INF/lib "));
// Create the emitter configuration.
HTMLEmitterConfig hc = new HTMLEmitterConfig( );
// Use the "HTML complete" image handler to write the files to disk.
HTMLServerImageHandler imageHandler = new HTMLServerImageHandler( );
hc.setImageHandler( imageHandler );
// Associate the configuration with the HTML output format.
config.setEmitterConfiguration( HTMLRenderOption.OUTPUT_FORMAT_HTML, hc );
engine = new ReportEngine(config);
IReportRunnable report =
engine.openReportDesign(reportReposPath+"/"+reportName);
//Create task to run the report and render the report
IRunAndRenderTask task = engine.createRunAndRenderTask(report);
//Set Render context to handle url and image locataions
HTMLRenderContext renderContext = new HTMLRenderContext();
renderContext.setImageDirectory("image");
HashMap contextMap = new HashMap();
contextMap.put( EngineConstants.APPCONTEXT_HTML_RENDER_CONTEXT,
renderContext );
task.setAppContext( contextMap );
//Set rendering options - such as file or stream output,
//output format, whether it is embeddable, etc
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputStream(out);
//options.setOutputFileName("/example.html");
options.setOutputFormat("html");
task.setRenderOption(options);
task.run();
engine.destroy();
out.flush();
}catch(Exception e)
{
log(e);
}

Hi,
Can you file a viewer bug in bugzilla? This sounds like a problem, there is
no reason it would work with one url and not the other, particularly in that
place of the code.
Thanks,
David

Henry,
I think you have to create that image directory yourself. It should be under
ReportEngine I believe. Make sure the web-app process has rights to write
there.
Thanks,
David

Sorry that I have been busy in last week.
I created the "image" folder in %BIRT_ENGINE% and many other locations
that I bet BIRT might use. But none of them is used. When I render the
report as HTML, the chart (the .png file) seems not even generated.
BIRT, as a process of JBoss, has full privilege to write file in any
folder path of my PC. So I guess BIRT just don't know the right path to
handle image. But I don't see any exception being thrown.

Did you try to get the webviewer example available for download and deploy
it? I am pretty sure it should work with JBoss. then you would be able to
see what's the difference in your code and the example.
Thanks,

Yes, as said in the first post, the chart is successfully generated when
using the webviewer example deployed to JBoss. It is generated in
eportimages.
rt-viewer.war
ok, I will try to dig into those code to see what's the difference.

I decompiled some classes of the webviewer example to compare with my
webapp, and found out what's wrong.
First of all, I didn't set the BaseImageURL. It must be set and should be
a relative path:
renderContext.setBaseImageURL("report/images");
Secondly, I set the ImageDirectory to be a relative path, while that it
should be an absolute path:
renderContext.setImageDirectory(this.getServletContext().get RealPath( "/report/images"));
