Tooltips when the report is exported as image

[njrfrens]

I'm displaying a bar chart in my jasper report.

In the chart, I'm customizing the tooltips with my own expression for each group.

When I view the report in the JRViewer through IReport, I could see the tooltips properly.

 

I'm exporting this report as an image and showing it in my webpage using JRGraphics2DExporter.

That time, I couldn't see the tooltips.

Below is the code I'm using for exporting the chart as image...

Code:

JasperPrint jasperPrint = getJasperPrint();JRGraphics2DExporter exporter = new JRGraphics2DExporter();exporter.setParameter (JRExporterParameter.JASPER_PRINT, jasperPrint);exporter.setParameter (JRGraphics2DExporterParameter.GRAPHICS_2D, pageImage.getGraphics ());				Map imagesMap = new HashMap();HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(false);session.setAttribute("IMAGES_MAP", imagesMap);exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR, Boolean.FALSE);exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap);exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, FacesContext.getCurrentInstance().getExternalContext()+"/images?image=");exporter.setParameter(JRExporterParameter.PAGE_INDEX, new Integer(0));exporter.exportReport ();

Can any one please inform if there is any solution for it...?

There is no built-in code that would export a report to a image with tooltips.

Exporting the report to an image in order to show it in a web application is a rather unusual thing to do.  Displaying the report in an applet or using the HTML exporter are the standard ways of using reports in web applications.
