Jasper报路径问题，在App server上运行时找不到.jasper文件

Question

When running in Tomcat (out of Eclipse w/debugger), how are you supposed to get a.jasper file (say as an InputStream) for JasperFillManager.fillReport() to use? Currently our.jasper files are within /WEB-INF/jasper .

I need a solution that doesn't break based on where you happen to be running the report from. If it's being debugged while running Tomcat from Eclipse, System.getProperty("user.dir") returns C:/Eclipse... but obviously, that path will be different when it's deployed to a server.

How do you get around this?

Answer 1

If you do not plan to replace the.jasper file after it was created then you could use the resources and getResourcesAsStream .

Answer 2

I believe you can use the application object (assuming you're using JSPs rather than servlets - I've not been using them)

InputStream input = new FileInputStream(new File(application.getRealPath("/WEB-INF/jasper")+"/report.jasper"));

Answer 3

I've managed to get this working running from tomcat/eclipse by changing the Tomcat launch configuration working directory from within Eclipse. This lets you just pass a relative path to fillReport() in the Java code. But I've yet to try testing from within websphere... (something tells me I'll be cursing IBM again soon).
