Can you give some more detail on how you are generating it?
Are you using your own servlet or using the webviewer?

Hi Jason,
These are the details below:
1) I am using My own servlet
2)The enivironment is linux
3)Open jdk version 1.6.x
4)I am rendering the response on the servlet.
5)Birt version I am using is 2.6.0
below is the code of the report rendering,
ReportEngine engine = null;
IReportRunnable report = null;
engine = BIRTEngineFactory.getReportEngine("C:\birt-runtime-2_6_0\birt-runtime-2_6_0\ReportEngine ");
report = engine.openReportDesign("C:\MyReport.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask( report );
RenderOption options = new RenderOption( );
options.setOption(IPDFRenderOption.PAGE_OVERFLOW,
IPDFRenderOption.OUTPUT_TO_MULTIPLE_PAGES);
options.setOutputStream(os);
task.setRenderOption( options );
try{
//System.out.println("beforeeeeeeeee run");
task.run();
//System.out.println("aftreeeeeeee run");
}catch ( EngineException e1 )
{
e1.printStackTrace();
System.err.println( "Report " + name + " run failed.\n" );
//System.err.println( e1.toString( ) );
}
regards,
Srikanth

Do you set the supported image formats in the servlet?
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat("html");
options.setImageDirectory(sc.getRealPath("/Images"));
options.setBaseImageURL(request.getContextPath()+"/Images");
options.setSupportedImageFormats("JPG;PNG;BMP;SVG");
Look at the generated html and look for the img src tag. Verify the
image gets created.

Are you getting anything in the log?
Can you try html and see if it is creating the images?

Can you post what the img src tag is showing? Do you get anything in
the log file?

Also as a test can you deploy the web viewer and see if html and pdf
show the report?

What version of BIRT are you using?
If you are using one of the newer versions 2.3-2.6
Replace the HTMLRenderContext code with just this:
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML) ;
options.setOutputStream(resp.getOutputStream());
options.setEmbeddable(true);
options.setImageHandler(new HTMLServerImageHandler());
options.setBaseImageURL(req.getContextPath()+"/images");
options.setImageDirectory(sc.getRealPath("/images"));
create the images directory at the top level of your web app.
req and resp are the request and response objects.

I am not certain what is happening. If you use the viewer and export to
pdf on linux does it work?

If you are using the Chart Engine this can be done, but with the BIRT
report engine I do not know of a way. You could look at the
IHTMLImageHandler interface, but most of the methods return strings.
This is the interface that the HTMLServerImageHandler class implements.
When the engine runs it creates the file and sets up an image map to
handle interactivity which works with the img src tag in HTML. Could
you write a shell script to cleanup the files periodically?

Not sure what you need here, but you could add a jsp to the viewer that
is called before going to the viewer. The JSP could check the format
and then forward to either the viewer or another servlet which uses the
engine.
