JDBC connection

[mgl70]

Hi,

I got a problem with oracle9i connection through JDBC. Everyday I am able to connect to the oracle database and manipulating the data through JDBC connection and sql prompt. Today, I am getting the sql prompt but while connecting to the oracle database through JDBC , I am having this kind of error.

java.sql.Exception: IO exception: The network adoptor could n't establish the connection.


I did not change any code or files in oracle or java.
database and listener are started fine.

What could be the problem.
thanks,

I don't know, whether you need a network-connection to get the sql-prompt, but 'network-adaptor' sounds like network-problem.

Did you ping the ora-server?
May someone else have changed some settings?

This is a DNS error, or failure to resolve the host you are connecting to.
