Java EE 8 Design Patterns and Best Practices

Bean sent on the event

FileEvent is a bean that is sent to the event—the observers will receive this:

import java.io.File;public class FileEvent {    private File file;    private String mimeType;    public FileEvent(){}    public FileEvent(File file, String mimeType){        this.file = file;        this.mimeType = mimeType;    }    public File getFile() {        return file;    }    public void setFile(File file) {        this.file = file;    }    public String getMimeType() {        return mimeType;    }    public void setMimeType(String mimeType) {        this.mimeType = mimeType;    }}
