[java] applet read file on server

mr2071 · 2002-06-06T01:30:17

I''m getting this error in my applet: Exception: java.security.AccessControlExeption: access denied (java.io.FilePermission ..\maps read) I''ve tried putting in the full path to the directory and it still doesn''t work. Also, I put in a public static void main(String args[]) that uses the readDir method and it worked perfectly so I don''t think it has anything to do with the actual file system but rather the applet itself. I thought maybe the applet was trying to access a file on the users computer but I''m not sure how to enforce it to read off the server. any ideas? Thanks for the help!

Are you using appletviewer or a browser? I think I remember that appletviewer failed on this.

reading a file from the server works fine now but can anyone help with writing to a file on server?

I tried to pretty much do the reverse but I get an exception.

  public String readFile(String fileName, String data)throws IOException{                URL serverUrl = new URL(fileName);                URLConnection urlc = serverUrl.openConnection();                BufferedWriter bw=new BufferedWriter (new OutputStreamWriter (urlc.getOutputStream()));                for(int k=0;k<data.length();k++){    bw.write(data.charAt(k));}bw.close();}

thanks

You can''t write over http (which is what you''re reading through). You need to have an ASP/PHP/JSP/Servlet/Perl script/etc. on the web server that can accept your data and store it for you.
