hi mukul -
this list is not actively monitored by sun. put another
way, if you post a message to the list from an address
which is subsribed to the list then your message will
get posted to the list. we require posters to be registered
to minimize the "spam" type messages.
regarding content for this list, in general, anything
which pertains to the combination of the above is fair
game in my book:
servlet
http
cgi
design discussions (eg connecting to a db)
session management
servlet engines (and specification compliance)
html
jsp (core jsp questions should go to
[EMAIL PROTECTED])
form processing
javaScript and/or servlets
the boundaries are by definition broad and can finger into
many disciplines at which point the discussion should possibly
not continue on this list. we look to the members to help
monitor the "signal to noise" ratio here.
as to why you didn't see your email posting, there could
be a number of reasons:
you posted from an address not registerd
on the list. it is quite common for any one
person to have 3 or more addresses.
your registration is configured such that you
will not receive copies of your posts. you
can administer your account at:
http://archives.java.sun.com/archives/servlet-interest.html
the list server could be a bit sluggish.
hope this helps,
- james
