Set the isLazy flag for the image and use a string expression. If the flag is set, the JR engine would not try to load the image and the Html export would refer directly the image location.

 

HTH,

Are you sure it doesn't work? Maybe you got the html page from the browser's cache?

 

Try to run the "images" sample in the demo/samples folder of the JR distribution and see whether the image having isLazy set produces an img element in the resulted html with the right source URL.

Hi,

 

i used a anather method. and it work.

look that:

 

if(formatRapport.equals("web"))

{

JRHtmlExporter exporter = new JRHtmlExporter();

exporter.setParameter(JRHtmlExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRHtmlExporterParameter.OUTPUT_STREAM, outStr);

 

//permet notamment de voir apparaître les accents

exporter.setParameter(JRHtmlExporterParameter.CHARACTER_ENCODING, "iso-8859-1");

exporter.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);

 

//false:supprime les images, true: essaye d'afficher les images

exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, Boolean.FALSE);

//déclare où on doit récupérer les images

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, reportSrcPath+"imagesJasper/");

//déclare où doivent être stocké les images

exporter.setParameter(JRHtmlExporterParameter.IMAGES_DIR_NAME, reportSrcPath+"imagesJasper/");

//déclare que les images doivent être sauvegardé sur la base

exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR , Boolean.TRUE);

exporter.exportReport();

}

 

with that, i can use the picture in my reports. I point out that it work in my browser IE but not with mozilla.
