I am using BIRT RE API to generate a html report with chart. I am running birt in my custom web application on a tomcat server, and i have a apache web server in front.

I have problems getting my heading around how to show the chart. What is the easiest/best practive way to show the chart image in the report ?

cant understand how to use and set base image url and imagedirectory on htmlrenderoption?

this example code under shows the report but not the chart....is there any documentation or easy example ?

IReportRunnable runnable = reportEngine.openReportDesign(rptdesign);
IRunAndRenderTask runAndRenderTask = reportEngine.createRunAndRenderTask(runnable);
runAndRenderTask.setParameterValues(discoverAndSetParameters(runnable, request, reportEngine));

HTMLRenderOption htmlRenderOption = new HTMLRenderOption();
htmlRenderOption.setOutputFormat(format);
htmlRenderOption.setOutputStream(response.getOutputStream());
htmlRenderOption.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");
//htmlRenderOption.setImageHandler(new HTMLServerImageHandler());
//htmlRenderOption.setBaseImageURL(request.getContextPath() + "/images");
//htmlRenderOption.setImageDirectory(sc.getRealPath("/images"));

Have a look at this devshare it has quite a few examples using the BIRT API. There should be one in there that shows how to display a chart in a webapp.

Where do you define sc? Do you have this above in your code?

ServletContext sc = request.getSession().getServletContext();

If so, that looks right. You could always test with a static location for the image directory, like:

options.setBaseImageURL("images");
options.setImageDirectory("E:/JBoss/jboss-as-7.1.1.Final/standalone/deployments/JSF_JBoss.war/images");
