我是jasper报道的新手。我正在尝试使用List生成发票帐单。
我提到了this帖子以获得一些帮助，但我得到了这个JRException
我的碧玉填充代码
String [] prod = request.getParameterValues("prodn[]");
String [] pkgdate = request.getParameterValues("pkgdate[]");
String [] manufact = request.getParameterValues("manufact[]");
String [] exp = request.getParameterValues("exp[]");
String [] batch = request.getParameterValues("batch[]");
String [] unit = request.getParameterValues("unit[]");
String [] qty = request.getParameterValues("qty[]");
String [] subtot = request.getParameterValues("subtot[]");
Map<String, Object> param = new HashMap<String, Object>();
jasperPrint = JasperFillManager.fillReport(jasperReport, param, getDataSource(prod,pkgdate,manufact,exp,batch,unit,qty,subtot));
JasperViewer.viewReport(jasperPrint, false);
}
catch (Exception e) {
e.printStackTrace();
}
}
private static JRDataSource getDataSource(String[] prod, String[] pkgdate,
String[] manufact, String[] exp, String[] batch, String[] unit,
String[] qty, String[] subtot) {
// TODO Auto-generated method stub
Collection<DataBean> coll = new ArrayList<DataBean>();
DataBean bean = null;
for(int i=0;i<prod.length;i++)
{

coll.add(bean);
}
return new JRBeanCollectionDataSource(coll);
}

答案 0 :(得分：1)
您必须使用字段的名称作为bean中声明的字段。
因此，而不是<field name="pkgdatelist"...使用<field name="p_pkg"...等
