is it possible to store the PrimeFaces exported data programmatically?

Question

I need to store the exported data into some file as string or as excel format and I want to send that file using email.

my current export statement is

 <p:dataExporter  type="xls" target="tableWbTicketold" fileName="TicketOldReport" />

Answer 1

you have two alternatives:

1. use postProcessor: <p:dataExporter type="xls" target="tbl" fileName="cars" postProcessor="#{tableBean.postProcessXLS}"/>. you can email the WorkBook inside tableBean.postProcessXLS, but this will not prevent the normal flow (file download dialog)

2. write your own DataExporter custom component extending PF classes and overriding: DataExporter.processAction, ExcelExporter.export

UPDATE

this way:

public void postProcessXLS(Object document)
{
    try
    {
        Workbook wb = (Workbook) document;

        File file = File.createTempFile("exporter-", ".xls");

        FileOutputStream out = new FileOutputStream(file);
        wb.write(out); // or write in mail body
        out.close();

        // do what you need with file

        file.delete();
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }
}
