从代码访问war文件夹中的文件

Question

I am finding it hard to access a file inside my war folder from a code in my java web project.

This is my file structure

the java code I am using is inside the package com.abl.tf.dao .

I am trying to access the the file testreport.jrxml which is inside the war->reports folder.

This is what I have tried and this gives me the exception file not found .

net.sf.jasperreports.engine.design.JasperDesign design = JRXmlLoader.load(
                    new LegacyJasperInputStream(new FileInputStream("/TFProject/reports/testreport.jrxml"))
                    );

could you please help me to access that file from the code.

Thanks in advance!

Answer 1

You need to access the file as a resource. You do it like so:

net.sf.jasperreports.engine.design.JasperDesign design = JRXmlLoader.load(new LegacyJasperInputStream(getServletContext().getResourceAsStream("/reports/testreport.jrxml"));
