Java Programming question

I've made an simple applet which stores a mail address inputted fron the user. Then it writes the address to a file "maillist.txt", this goes perfectly when I use the random access method on my local machine, but as this is a applet, I should use an URL to save the information.
Then the problem is there are no random access methods in the URL package. Are there any workarounds for this, other than reading the whole datafile into the applet?

One way to go about this is to have a servlet handle the writing to the maillist.txt file server-side. The servlet can use a random access method. Then you just communicate with the servlet and send the data. You can use a number of solutions for client-server-side communication including sockets in the java.net library, RMI, APIs like NSAPI and ISAPI (I believe) or a number of other tool based solutions. Your choice is dependent on whether or not their is going to be more functionality that might be hosted server-side in the future.

Another posibility is to set up a complete server application on the server. And follow up on weka's advise.

The use of a Server or a Servlet would depend on the ammount of trafic you are expecting to handle. For small loads, servlets work fine. For high trafic, full server apps are better since they don't have to be reloaded each time a request is processed.

One final alternative, albeit more work, is to use JDBC and a data base. You could then make the requests dirrectly from the client and avoid a server/servlet solution. But this would imply using a straight JDBC driver, not and ODBC bridge, since a bridge would imply installing an ODBC driver on the client box.
