hello gwen,
it should be at Applet calling the Servlet & not vice-versa as Applets, by
themselves, cannot talk to the server. they do so with the help of Streams.
you have to first make an applet. in the applet, specify an object of the URL
class, the URLConnection class & of course, the DataInputStream class. the
URLConnection class will make the connection b/w the applet & servlet.
well, you must go by the following steps:
1. create an applet calling the servlet.
2. create a servlet performing yr jdbc tasks.
3. create an html page calling the applet.
4. if u r using Java Web Server 2.0, compile the applet file & the servlet
file.
5. copy the applet.class file & the html page in the "public_html" folder.
6. copy the servlet.class file in the "servlets" folder.
7. in yr browser, call "http://hostname:port/html.html", the html page that u
created & copied in the pubic_html folder.
but, u must remember to use response.setContentTYpe("text/plain") in yr
servlets file. this is b'coz applets communication is in simple ASCII format.
well, i hope to have clarified some of yr doubts. any suggestions on this will
be appreciated.
best regards,
amit bhatia.
