unable to read file from war file

[Jigar Naik]

hi,

i'm trying to display report created using jasper report.

following is the code of my jsp which contains one button on click of that button my servlet is getting called

  
<form name="reportfrom" method="post" action="/SimpleJasper/report.do">
<input type="submit" name="submit" value="Show Report" />
</form>

My Servlet code which will call the static method of java class

  if (req.getRequestURI().equalsIgnoreCase("/SimpleJasper/report.do")){
System.out.println("Inside report.do servlet................................................");
ContactUtils.runReport();
}  

and following is my java class's method which is being called from servlet

  
 
public static Connection connectDB() {
        Connection jdbcConnection = null;
        try{
            Class.forName("com.mysql.jdbc.Driver");
            jdbcConnection = (Connection)DriverManager.getConnection("jdbc:mysql://localhost:3306/utility?user=root&password=root");
        }catch(Exception ex) {
            String connectMsg = "Could not connect to the database: " + ex.getMessage() + " " + ex.getLocalizedMessage();
            System.out.println(connectMsg);
        }
        return jdbcConnection;
    }
    public static void runReport() {
        try{
[B]        String reportFile = "report/contactReport.jrxml";
            JasperDesign jasperDesign = JRXmlLoader.load(reportFile);[/B]
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            Class.forName("com.mysql.jdbc.Driver");
            Connection jdbcConnection = (Connection)DriverManager.getConnection("jdbc:mysql://localhost:3306/utility?user=root&password=root");
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, jdbcConnection);
            JasperViewer.viewReport(jasperPrint);
        }catch(Exception ex) {
            String connectMsg = "Could not create the report " + ex.getMessage() + " " + ex.getLocalizedMessage();
            System.out.println(connectMsg);
        }
    }  

ERROR on console

  
15:10:57,895 INFO  [STDOUT] Inside report.do servlet................................................
15:10:57,895 INFO  [STDOUT] Could not create the report java.io.FileNotFoundException: report\contactReport.jrxml (The system cannot find the path specified) java.io.FileNotFoundException: report\contactReport.jrxml (The system cannot find the path specified)
  

however i'm also packaging jrxml file in report folder

so my war file folder structure is as follows.

WAR file/report/*.jrxml files....

but i am still getting the IO error... any perticular reason begind it ???

You can not do normal disk I/O from applications that are running from packed war files.

You'll need to either figure out how to get your container to unpack the war file on deployment or use ServletContext.getResourceAsStream and figure out how to pass a stream to JasperReports instead of a file path.
