Hi

I am facing a problem while generating reports that contains Chart &
images using the BIRT report engine.I am creating the report
templates with the eclipse BIRT plugin.These templates i am giving as
an input to BIRT engine which is a part of my web application.
This successfully
generate(HTML format) the report but when i open the report,the
images & charts are not displayed.

In the BIRT site they r saying that we have to set the image handler
i,e CompleteHTMLImageHandler or ServerHTMLImageHandler.
I have used both the options but of no use.

Can anyone help me in setting the configuration for the BIRT to
support images & charts.
Thanks in advance

Vikas,

You have to set the image directory and base image URL right like this
below:

HTMLRenderContext renderContext = new HTMLRenderContext( );
renderContext.setImageDirectory( EngineAccessor.ImageDirectory );
renderContext.setBaseImageURL( request.getContextPath( ) +
EngineAccessor.ImageBaseUrl );

The image base url will be used to construct the URL of your embedded
image/chart in the report. The image directory is the physical location
engine uses to store generated image/chart. You have to make sure the
image can be loaded by the url constructed from that base image url.

For example in Birt viewer, we define image dir as "/report/images", base
image url to be "/report/images" too. Also make sure the "/report/images"
is available in your web app's doc root. This is a very simple and quick
solution and you can develop more advanced one.
