I tried a loop in the servlet but it doesn't work. I get the IOException
class servlet not found. I thought that putting a loop around your query
would make logical sense because the query itself works but looping it
doesn't. Do you think because I'm using JDBC and a loop there's some
interference somewhere?
Hi willard,
I think instead of continuously making queries from applet to servlet, it
will
be better if u put a loop in servlet to execute same query for updated data
in
some time intervals & start this loop when user first see this page. Then
servlet will continuously go on sending data to applet & applet will just
read
the data. servlet will stop this loop if user wish to stop & send that
request
to servlet.
We can do it using URL & URLConnection class.
1. Make a conenction to ur servlet using URL & URLConnection.
2. Get date & time of the content or u can use getLastModified().
3. See that the content is modified & then using getInputStream() method
read
the data from the URL COnnection.
4. Make servlet send the data to this URLConnection.
Thanks,
Vijay
