Hi all,

 

I add the following code to see if it works, but I get the exception:

JExcelApiExporter exporter = new JExcelApiExporter();

 

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, file.toString() + ".xls");

exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.TRUE);

 

exporter.exportReport();

 

//I also try to use JExcelApiExporterParameter, but I still get the exception

//exporter.setParameter(JExcelApiExporterParameter.JASPER_PRINT, jasperPrint);

//exporter.setParameter(JExcelApiExporterParameter.OUTPUT_FILE_NAME,file.toString());

//exporter.exportReport();

 

Here is the exception:

java.lang.NoSuchFieldError: IHDR

at com.keypoint.PngEncoderB.writeHeader(PngEncoderB.java:260)

at com.keypoint.PngEncoderB.pngEncode(PngEncoderB.java:185)

Would you mind to help me out.

 

Thanks in advance.

You seem to have conflicting versions of com.keypoint.PngEncoderA and com.keypoint.PngEncoderB on your classpath. If you have a jar named png-encoder-* on your classpath, move it at the beginning of the classpath. Otherwise, inspect all the jars on the classpath and see which contains these classes.

 

HTH,
