java.io.IOException: Content is not allowed in prolog. [message #646350]

Hi,

I'm upgrading from BIRT 2.3.1 to BIRT 2.6.1.

Most of my reports appear to work OK but all give this error in my tomcat log:

I didn't get this error in BIRT 2.3.1

Can someone please give me some guidance on how I go about fixing this?

Many thanks for your time.

Do these reports contain charts?
Can you reproduce the issue with the sample db?

Thanks for your answer.
No charts.

Through trial and error I have found that this probably has something to do with the way images are specified.

In previous versions it was OK to specify "images/red_gradient.jpg" for a background image in a style.

In this new 2.6.1 version I have found that this syntax gives that "Content is not allowed in prolog" error.

It's quite strange as although you get a big exception it does actually find and use the background image in the report that's produced.

In the end I replaced this image with a solid colour which isn't as pretty but I couldn't find a way of specifying the image so that it was found by BIRT and didn't give me the "Content is not allowed in prolog" exception.

I tried url("images/red_gradient.jpg") which avoided the exception but using this syntax BIRT wasn't able to find the image.

When you use images/red_gradient.jpg is the images folder in the
resource folder?

Yes... indeed BIRT finds the image ok and uses it in the report... it's just that you get the big exception which I needed to avoid.

Thanks for your time & help.

Well, the error can be reproduced.

I also upgraded from BIRT 2.5.1 to 2.6.1

if you use images in a report which are located in images/someimage.jpg, you'll always get tons of this messages in your catalina.out

if you use an image which is embedded in a library, the error messages do not occur.

Maybe it has something to do with using images in themes... i am using a BIRT 2.3 Library with 2.6.1 reportdesign files. If I don't use images in styles (like background images for table headers) the error does not occur. Still other images can be used in the report without any errors.

I'm getting this same error upgrading to 2.6.2 from I don't know which version. Was there any resolution to it? Thanks!
