Why a servlet couldn't get jasper report path ?

Question

I am a new comer to web application development in java and I am using net beans for this .

I am created a web application to print a jasper report in client side.I used a servlet for this purpose. In here I gained above problem . I gave file path in different ways . But finally I have to put file path with the current working directory(partition) . But I want to give it with the path of the src folder .

Also I've gave this path with the project name . But I had gain following exception .

net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: Jasper\JasperReport\src\java\jasper\Report.jrxml (The system cannot find the path specified)

It would be easier to help you if you pasted fragment of your code. But I'll try anyway.

Method JasperCompileManager.compileReportToFile takes as an argument a path to jrxml file, either absoulute or relative to working directory. And I think you shouldn't use that method in this case.

In your case I think it would be better to use something like this:

InputStream jrxmlFileStream = getClass.getResourceAsStream("/path/to/file.jrxml");
// this path should be relative to src folder
JasperCompileManager.compileReportToStream(jrxmlFileStream, reportFileOutputStream);
// reportFileOutputStream - an OutputStream that writes to destination file

(I've omitted here any exception handling or resources closing)
