    Default Generating a Batch File - Static Method Error

    Hey guys, I'm clearly new here, scoured the internet for a solution to my problem but could not find one, so I figured I'd make a post on the first forum I found, which is this one! (congratulations).

    Anyways:

    import java.io.*;
     
    public class UpdateACL {
        private FileOutputStream fos;
        private DataOutputStream dos;
    	private static String projectName = "";
    	private static String projectPath = "xcopy C:\\st22615_SharedTools_mainline_intg\\vobs\\sharedtools\\src\\ClearCase\\triggers\\acl\\project\\" +
    						  projectName + "\\* \\0\\cm\\acl\\project\\" + projectName + "/y /r /s /i" + "pause";
     
     
        public void ChangeACL() throws FileNotFoundException, IOException {
     
            File file;
            file = new File("C:\\samplenote.bat");
            fos=new FileOutputStream(file);
            dos=new DataOutputStream(fos);
            dos.writeBytes(projectPath);
        }
     
    	public static void main(String args[]){
    	try{
    		System.out.print("Enter the project name:");
    		InputStreamReader converter = new InputStreamReader(System.in);
    		BufferedReader in = new BufferedReader(converter);
    		projectName = in.readLine();
     
    		ChangeACL(); //Calling this method gives non-static method call in static context error
     
    } catch (FileNotFoundException e) {
        System.err.println("FileNotFoundException: " + e.getMessage());
     
    } catch (IOException e) {
        System.err.println("Caught IOException: " + e.getMessage());
    }
    }
    }

    I'm basically trying to generate a batch file that will hold that string, that I can run immediately after it is generated...however I cannot call Change.ACL(), even though it is in the same class? Confusing...

    If anyone could provide insight on this that would be great.

    Cheers.

    I cannot call Change.ACL()
    Please post the full text of the compiler's error message.
    If you don't understand my answer, don't ignore it, ask a question.

    Change the code to be either:

    public static void ChangeACL() throws FileNotFoundException, IOException {

    (notice the static declaration) or

    UpdateACL updateACL = new UpdateACL();
     
    updateACL.ChangeACL();

    in your main() method.
