Hi,
This is a great article, and worked like a charm in a very first attempt. Even though I dont have a lot of experience in Applet am able to write to file succesfully.

I do have one further request, Can you please let me know if this applet can be called with out the AppletViewer (i mean directly from html). I am currently able to load WriteFile.html, but the write request did'twork(though it did not give any error).

Currently the AppletViewer is taking care of associating the policy file, and I dont know how I can associate the WriteFile.policy with the applet call.

Thanks

Hi,

This is a great tutorial. I know this work in an applet viewer, but I am trying to get it to work TRHOUGH a web browser. Your READ an applet works fine through a broswer, but this write one does not seem too.

Any ideas how I can write to a file, but using the applet through a web browser?

Thanks!

Hi there!

Is it possible to write a file from applet using Url connection as we can see at reading?
I have tried the folowing lines:

URL url = new URL(getCodeBase(), "name.txt");
URLConnection urlConn = url.openConnection();
urlConn.setDoOutput(true);
urlConn.setUseCaches(false);
OutputStream out = urlConn.getOutputStream();

The problem is the getOutputStream().
It is throws UnknownServiceException: protocol doesn't support output

Do you have any idea to handle this exception?

Thank you for your help in advance.

I am looking forward your answer.

Best Regards,
Szabolcs
