Exception at Connect to Sybase / TCP_NODELAY

[Karlheinz Meyer]

Hello,

I am new to JDBC and I have a problem connecting to Sysbase ASA 6.0 by
Jconnect 4.2 on WinNT 4 SP6.
A Stack Trace is below ( + IP Config). If the Client (Jdk 1.1.2, Jdk 1.2.2)
is on WinNT 4 SP6, I get the Exception.
If I compile and run the Client on Linux (Jdk 1.1.8), the connection works.
Does anybody know the problem? Docs of Sybase just talk of bad
TCP-Configuration, but not more.
