I got stucked to read a file which is at the server, i used this code :

String ipaddr="";
int ch;
try
     fis=new java.io.FileInputStream("server.ini");
     while((ch=fis.read())!=-1)
          ipaddr=ipaddr+(char)ch;

Hello hikiran.
The server.ini file should reside in your application working directory. If it's not there, then the JVM won't find it. Otherwise you could specify an absolute path to the file, but your application will be less portable. Another choice you have is to define an environment variable which tells your app where the server.ini file resides, with the command
  java -Dmyapp.ServerIni=C\SomeFolder\server.ini myappThen you retrieve the pathname with:
   String path = System.getProperty("myapp.ServerIni");This way your app does not depend on the filesystem on which it's been installed to, because changing the command line that starts your app will be enough to have it working.
Note: if you have to read a text file consider using the java.io.BufferedReader class which lets you to get rid of the different text file formats problems you find when you move to a unix like platform (newline characters are different).
