Question

I’m developing a project with Maven. In a class to send e-mails, in run and dev modes, I get the following error: Caused by: java.io.FileNotFoundException: jQuery/images/logo.png (Ficheiro ou directoria inexistente) ==> translation = File or directory not found.

I’ve tryed lots of paths, like “./jQuery/images/logo.png”, “/jQuery/images/logo.png” and others. The full relative path is: “src/main/webapp/jQuery/images/logo.png”.

In “target” folder, the path is “project-1.0-SNAPSHOT/jQuery/images/logo.png”.
Inside war file, is “jQuery/images/logo.png”.

I don’t think it’s important, but I’m using NetBeans 7.1.1 as IDE.

I found that the absolute path returned in runtime is “/home/user/apache-tomcat-7.0.22/bin/jQuery/images/logo.png”!… It’s not the project path!

How can I get a file in webapp folder and descendents from a Java class, in a Maven project?

The code is:

MimeBodyPart attachmentPart = null;
        FileDataSource fileDataSource = null;
        for (File a : attachments) {
            System.out.println(a.getAbsolutePath());

            attachmentPart = new MimeBodyPart();
            fileDataSource = new FileDataSource(a) {

                @Override
                public String getContentType() {
                    return "application/octet-stream";
                }
            };
            attachmentPart.setDataHandler(new DataHandler(fileDataSource));
            attachmentPart.setFileName(fileDataSource.getName());

            multipart.addBodyPart(attachmentPart);
        }

        msg.setContent(multipart);
        msg.saveChanges();

        Transport transport = session.getTransport("smtp");
        transport.connect(host, from, "password");
        transport.sendMessage(msg, msg.getAllRecipients());

The path .../apache-tomcat-7.0.22/bin/jQuery/... is really odd. bin contains scripts for Tomcat, it should not contain any code nor any resources related to your application. Even if you deploy your app in the context /bin, the resources would end up under `.../apache-tomcat-7.0.22/webapps/bin/...

This looks like a mistake made in an earlier deployment.

Now back to your question. To get the path of resource of your web app, use this code:

String absolutePath = getServletContext().getRealPath("/jQuery/images/logo.png");
