Hi ,
Thanks for the quick reply. Sorry. I should have stated my problem in a better way.
I am trying to deploy a sample multimedia application given in the NokiaSeries40 book codes, using NetBeans. The client end needs to submit a photo, an audio file and a message at the server end. I was not able to generate the .war file successfully as the webroot, file root concept was not clear.
I have uploaded the server end code of the application at the URL -(
http://sites.google.com/site/cuteteddy02/file-cabinet)
From the source code files, here is the entire servlet code which is using webroot and fileroot .
public class BlogServlet extends HttpServlet {
private static int NO_OBJECT = 0;
private static int PHOTO_ONLY = 1;
private static int AUDIO_ONLY = 2;
private static int PHOTO_AUDIO = 3;
private static int SUCCESS = 1;
private static int FAILURE = 2;
private static
String fileroot = null;
private static String webroot = null;
public void init() throws ServletException {
InputStream in =
getClass().getResourceAsStream("/conf.prop");
Properties prop = new Properties ();
try {
prop.load (in);
fileroot = prop.getProperty("Fileroot");
webroot = prop.getProperty("Webroot");
} catch (Exception e) {
e.printStackTrace ();
fileroot ="/Users/juntao/Java/tomcat/jakarta-tomcat-4.1.24/webapps/BlogServer/content/";
webroot = "/BlogServer/content/";
}
}
