使用DynamicJasper API生成的html报表输出中没有图像

Question

I'm building a report with DynamicJasper API and I want to insert an image in a column.

I have:

FastReportBuilder drb = new FastReportBuilder();
drb.addImageColumn("Image", "image", "java.awt.Image", 500,false, ImageScaleMode.NO_RESIZE, detailStyle);

And the property for "image" is built from an URL:

Image image = ImageIO.read(new URL(pathToImage));

The problem I'm having is the image displays in PDF output but not in HTML output. Inspecting the generated source, I see the following:

<img src="nullimg_0_0_16" style="height: 50px" alt="">

Answer 1

Thank you Alex K but that didn't work for HTML output.

One needs to use jasper's ImageServlet. The solution is documented here:
