这是bean中的代码.
and here is the code in the bean .
try {
String reportPath = FacesContext.getCurrentInstance()
.getExternalContext().getRealPath("reports");
System.err.println(reportPath + "\\report1.jrxml");
JasperCompileManager
.compileReportToFile(
"C:\\reports\\report1.jrxml",
"C:\\reports\\report1.jasper");
System.err.println(reportPath);
JRBeanCollectionDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(
orders);
System.err.println(reportPath);
JasperPrint jasperPrint = JasperFillManager
.fillReport(
"C:\\Projects\\reports\\report1.jasper",
new HashMap<String, Object>(),
beanCollectionDataSource);
System.err.println("Check");
JasperExportManager
.exportReportToPdfFile(jasperPrint,
"C:\\Projects\\reports\\report1.pdf");
System.err.println("Check");
} catch (JRException e) {
System.out.println(e);
}
我正在使用jasperreports 4.1.3 .jar和itextpdf 5.4.5 .jar
I am using jasperreports 4.1.3 .jar and itextpdf 5.4.5 .jar
推荐答案
The
java.lang.NoSuchMethodError:
com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V
告诉您在类com.lowagie.text.pdf.PdfWriter中，您没有使用setRgbTransparencyBlending(Z)V方法.通常在使用不需要的jar版本时会发生这种情况.
is telling you that in the class com.lowagie.text.pdf.PdfWriter you are using no setRgbTransparencyBlending(Z)V method exist. Usually this happens when not required jar version is used.
在类com.lowagie.text.pdf.PdfWriter中找到包含方法setRgbTransparencyBlending(Z)V的jar的适当版本:我猜是itext-2.1.7.jar.
Find the appropriate version of the jar containing the method setRgbTransparencyBlending(Z)V in the class com.lowagie.text.pdf.PdfWriter: I guess itext-2.1.7.jar.
