Hello,

i am trying to display charts in HTML reports. It works in eclipse, with
the birt viewer but in my web app I can not display any charts. It works
when I choose PDF output format.

When I look at the generated html page, it seems that the img tag (which
should display an image from a temporary image file) does not have any
source.

Here is the img tag when it works (with eclipse or the web app viewer):
<img src="/birtViewer/run?__imageID=custom6" style=" width: 400pt; height:
250pt;">

Here is the img tag when it doesn't work (with my web app):
<img style=" width: 400pt; height: 250pt;">

It seems that a new http post is done when the report is displayed to get
the temporary image file. I can not figure out how can i do in my web app.

thanks for your help

Hi jauze,

I had the same problem. You have to add the imageDirectory and the
baseURL. Then it works.

Greetings

Hi Thomas,

thanks for your answer.

Do you use the PlatformServletContext class in the EngineConfig ?

something like that:
config.setEngineHome( "" );
IPlatformContext context = new PlatformServletContext( servletContext, url
);
config.setEngineContext( context );

thanks

Hi jauze,

if you use the example given on the birt website you have to add following
lines.

HTMLRenderContext context= new HTMLRenderContext();

context.setImageDirectory("E:\\Entwicklung\\JBoss4\\server\\default\\deploy\\test.war ");

context.setBaseImageURL("http://localhost:8080/test");

Hope it helps.
