在apache服务器上部署war文件时，jasper报告不起作用

Question

I have created jasper report and it woks perfectly on netbean but when i build war file and deploy it on apache server then it not works....

I Tried So hard on this problem spend whole day but didn't find any solution please help me out to solve this

Here is My Code

String loc = "C:\\Program Files\\report\\
public void CustBillPrint(String BillNo) {
        String path = loc + "customer-bill-1.jasper";
        Map param = new HashMap();
        param.put("billno", BillNo);
        try {
            JasperPrint jasperPrint = JasperFillManager.fillReport(path, param, con);
            JasperViewer.viewReport(jasperPrint, false);

        } catch (JRException e) {
            System.out.println(e);
        }
    }

I already tried many ways are as follows:

InputStream path = this.getClass().getResourceAsStream("report/farmpati-1.jasper");

InputStream path = new FileInputStream(new File("web/report/farmpati-1.jasper"));

InputStream path = new FileInputStream(new File("").getAbsolutePath() + "/reports/logReport.jrxml");

String path = System.getProperty("user.dir") + "\\report\\";

String path = new File(".").getCanonicalPath() + "/web/report/";

And All This Alternative Work in NetBan But not working on apache when deploy as war

Answer 1

Use ServletContext 's getResourceAsStream() method to read a resource in a jar file in any web application..

ServletContext context = getServletContext();
InputStream is = context.getResourceAsStream("/farmpati-1.jasper");

please have look into Reading files in jar

I have found a possible answer on community.jaspersoft.com: http://community.jaspersoft.com/questions/536218/resolved-problem-subreport-reference-after-exporting-ireport-jasperserver

"In the report that's working, the subreport isn't just in the repository as its own report on the same level as the main report. There is also a copy of that subreport in the Resources "folder" for the main report."

That topic contains more than 1 solution, one of them is a resolved topic here on Stackoverflow: JasperServer: Unable to locate the subreport exception (warning: this is a very long, but detailed, read)
