Loading java files via HTTP

[Xmen]

Hi
I have created a small application and I need to load some files via HTTP protocol. I know this can be done in java, but I do no know the exact class and package to use. The files which I am trying to load are on my local computer (not an URL). I read the java API documentation, but was not successful. Can any one help.

This is how you can do it. Take a look on the example below.

try
{
   java.net.URL url = new java.net.URL("http://www.mywebsite.com/someplace/test.txt");

   InputStreamReader inStream = new InputStreamReader(url.openStream());
   BufferedReader in = new BufferedReader(inStream);

   String line = in.readLine();
   while(line!=null)
   {
      System.out.println(line);
      line = in.readLine();
   }
   inStream.close();
}
catch(Exception e)
{
   e.printStackTrace();
}

I think this is what you were asking for. If not, please do post back.

Thank you Praetor. This is exactly what I was looking for. I have questions in my mind, first will it work if the URL mentioned is on the local PC like "c:\test\ex.txt" and second will it be HTTP loading the files. Thanks for the help.

The following line does this through HTTP

java.net.URL url = new java.net.URL("file:///c:/test/ex.txt");

Any more queries feel free to post.

Note that solution is good for text files. This will work with binary files.

try {
URL url = new URL(urlParam);
InputStream is = url.openStream();
fos = new FileOutputStream(file);

byte[] buffer = new byte[1000];

int count = 0;
while((count = is.read(buffer)) > -1) {
fos.write(buffer, 0, count);
}
}
catch (IOException e) {
System.out.println("Error retrieving file: " + e.getMessage));
}
finally {
if (fos != null) {
try {
fos.close();
}
catch (IOException e) {
}
}
}
