Socket Exception Error

[balaji rangan]

Dear All,

Issue:- When applet sends POST data via browser, the server does not receive the same.
On checking the Java Console, the following error is displayed.
"java.net.SocketException: Unexpected end of file from server"

O.S :- Win XP, Service Pack 2
Browser:- I.E 6, Service Pack 2
Applet :- Signed Applet
VM :- Sun VM (1.4.2_06)

Note:- When MS VM is used, there is no issue, this is only happening with SUN VM.

Java Console details given below.

Appreciate if somebody could let me know why this is happening.

Hello dear friend java programmer. I think so that you applet need have a port number or socket number specifically to this server that you are describing please tell me more details what is the name server your . I will recompile this again with applet and the html post server to see something different

Ok. My Great Alfonso

Hello Alfonso,

I have the following scenarios,
1. The connection seems to have been dropped by the server.
2. A non-suuported HTTP version or format was used.
- HTTP 1.0 does not issue Status Lines that begin with "HTTP/1.1", so
if you expect a different version and it is not there, then this would
be an Exception (to the rule).
3. Packets are being dropped without retransmission from the server.
4. Non-Implemented Method (GET, HEAD, POST, TRACE, DELETE, PUT), if you
expect to get a POST and in reality get a TRACE, then the line will be different
and could possibly cause an error (but an exception?).
5. A timeout or connection was reset.

But i have not been able to get to the root cause.
Would be great if you could suggest.
