Question

I’m getting the stacktrace below printed to my log/console. I’m using Tomcat 6.0 and BIRT 2.6.2. It’s not stopping the viewer from displaying reports, but it is taking up precious space in the log.

I found someone having a similar problem here, but there’s no clear indication as to what the resolution was. Like the poster in that link, I am in the middle of upgrading to a new version of BIRT (2.6.2).

Let me know if you need any more information about my setup. I’m fairly new to BIRT. Any help is welcome, even if you can suggest a place to look.

Answer 1

This is from entering the background image property in the style of a report design.

In CSS, the backgroundImage property requires url('path/to/image.jpg').

body {
    background-image:url('path/to/image.jpg');
}

However BIRT appears to be rendering the following for the style:

body {
    background-image:'path/to/image.jpg';
}

In order to get around this I entered the following in the initialize script for every report design that uses the backgroundImage style:

reportContext.getDesignHandle().findStyle("blueresultsetheaderrow").backgroundImage = "url('images/BlueSortTitleBar.gif')";

I suspect that this is a bug, so I logged this one.
