JRViewer: limit offered save formats

[3rwin]

I am using JasperReports in a Java application and I'm using the JRViewer to view the reports.

 

How can I limit the offered formats in the JRViewer save dialog?

Maybe not the best way to do this but ...

 

Remove all the formats:

Code:

JRViewer viewer = new JRViewer(jasperPrint);
JRSaveContributor[] save = viewer.getSaveContributors();
for (int i=0; i<save.length; i++) {
  viewer.removeSaveContributor(save);
}

 

Add the ones you need (taken from the initSaveContributors in the JRViewer class):

Code:

[code] final String[] DEFAULT_CONTRIBUTORS = { "net.sf.jasperreports.view.save.JRPrintSaveContributor", "net.sf.jasperreports.view.save.JRPdfSaveContributor", "net.sf.jasperreports.view.save.JRRtfSaveContributor", "net.sf.jasperreports.view.save.JRHtmlSaveContributor", "net.sf.jasperreports.view.save.JRSingleSheetXlsSaveContributor", "net.sf.jasperreports.view.save.JRMultipleSheetsXlsSaveContributor", "net.sf.jasperreports.view.save.JRCsvSaveContributor", "net.sf.jasperreports.view.save.JRXmlSaveContributor", "net.sf.jasperreports.view.save.JREmbeddedImagesXmlSaveContributor" }; for(int i = 0; i < DEFAULT_CONTRIBUTORS.length; i++) { try { Class saveContribClass = JRClassLoader.loadClassForName(DEFAULT_CONTRIBUTORS); Method method = saveContribClass.getMethod("getInstance",(Class[])null); JRSaveContributor saveContrib = (JRSaveContributor)method.invoke(null,(Object[])null); viewer.addSaveContributor(saveContrib); } catch (Exception e) { } }

 

Remove the ones you don't need from the DEFAULT_CONTRIBUTORS.

I've limited the save formats as described in the example in the previous posting.

Everything worked fine the for several months.

I had to update to a newer version of JasperReports (from jasperreports-1.3.3.jar to jasperreports-3.1.2.jar)

and now i'm getting an Exception:

java.lang.NoSuchMethodException: net.sf.jasperreports.view.save.JRPdfSaveContributor.getInstance()

This code is working after JR 3.0
