I'm doing a registration form in Japer Report, when I call them from java and I run the generation of the document I get the following error:

java.io.FileNotFoundException: \WebCampeonatoDeportivo\src\net\cibertec\campeonatoDeportivo\documentos\ficha_inscripcion.jasper (El sistema no puede encontrar la ruta especificada)

This is the code that generated the document:

@SuppressWarnings({ "static-access", "deprecation" })
public void GenerarFichaInscripcion() throws Exception{
    SqlDBConexion cn = new SqlDBConexion();
    JasperReport jr = null;
    ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
    ServletContext context = (ServletContext) externalContext.getContext();
    jr = (JasperReport) JRLoader.loadObjectFromFile(context.getRealPath("/WEB-INF/docs/ficha_inscripcion.jasper"));
    try {
        JasperPrint jasperPrint;
        jasperPrint = JasperFillManager.fillReport(jr, null,cn.getConexion());
        JasperViewer jv=new JasperViewer(jasperPrint,false);
        jv.show();
        System.out.println("Visualizando el reporte en Desktop");
        System.out.println("Agregado exitosamente");
    } 
    catch (Exception e) {
        System.out.println("Error"+e.getMessage());
        //e.printStackTrace();
    }
}

It is an application made in Java Web with primefaces and Jasper Report.

The problem indicates that you can not find your file ficha_inscripcion.jasper

If the file is inside your web project you have to do the following:

ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
            ServletContext context = (ServletContext) externalContext.getContext();
            JasperReport desing = (JasperReport) JRLoader.loadObjectFromFile(context.getRealPath("/WEB-INF/docs/nombreReporte.jasper"));

In this example I have my file inside the folder WEB-INF there is a folder called docs and inside this folder is my file nameReport.jasper

Usually ExternalContext , it offers access to specific artifacts of Servlets or Portlets that JSF currently uses " under the covers. " For example, when running in a Servlet container, the HTTP servlet request, the HTTP servlet response, the HTTP session and the Servlet context and inherently all its artifacts as well.

Here you can find a example.
