Question

I have a function where I am trying to load a file to a URL object, because the example project said so.

public class SecureFTP {

    public static void main(String[] args) throws IOException , ClassNotFoundException, SQLException , JSchException, SftpException{
        File file = new File("/home/xxxxx/.ssh/authorized_keys");
        URL keyFileURL = this.getClass().getClassLoader().getResource(file);

I tried using SecureFTP.class.getResource, but it still could not compile it.

I am fairly new to Java, so I know I am doing something wrong.

Answer 1

It can’t compile because getResource takes a resource name (a String, and not a File) as parameter, in order to load a resource using the class loading mechanism (from the classpath). Using it with a File makes no sense. If you want to open a file, just use a FileInputStream or a FileReader.

See http://docs.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource%28java.lang.String%29, and include the compiler error message next time you have such a question.
