Not really. However, you can write a servlet to run on the server that will negotiate with the applet for operations to be undertaken locally to the server.Basically applets have the same access to the server that the browser does, and have the same limitations for the same

That makes sense.

Could I create a servlet to write the whole program?

I am looking to create a program that will allow people to edit files on the server via a webpage. When connecting the servlet would load a file on the server to a text field, the user could edit it then save. On saving the servlet would save the changes to the file on the server.

Sure. Depends how user friendly you want to be really, but it's certainly possible.It all depends upon your own skills and the tools available to the audience you're targetting.D.

Many thanks, please accept this Duke star as a token of my appreciation :)I have no servlet skills, but I am putting a "Servlet and JSP" book on to my O'Reilly bookshelf to see what I could do...

This isn't too bad.

If you've a bit of Java you shouldn't find it too hard to get a basic JSP up and running. Frankly they're quite a bit easier to write than applets, although the configuration hoops can be painful to clamber through.

I see that you do not need to any applet at all.

you can make an clean html form contains the fields you need and has an action which points to your Servlet, at submitting your form you can read any request parameters in your servet, then edit any file on server-side.

that's all.

Thanks.

Ahmad, I don't think that was necessarily a very helpful reply. Please make sure that you've read the whole thread before responding.
