hi I was trying to connect to oracle Database using type 4 thin drivers on win98. I downloaded the driver from oracle site and also downloaded some more drivers from other sites.While connecting to data base I ran into problems I am working for about two days on this thing but couldn't succeed.
I get the following message: Connection refused ...........
The driver is succefully loaded but when it tries to connect using
conn = DriverManager.getConnection("jdbc racle:thin:@server:1521 rcl","userid","password"); it gives the above message.
now I think that I am giving the host name incorrect I couldn't find any way in oracle to figure out the host name.
I am giving "jdbc racle:thin:@127.0.0.1:1521 rcl" I have also tried other options for host name like localhost etc.but it didn't resolve.I think that the listener for oracle is not listening at the port 1521. I tried telnet to check that but it failed to connect at this port.I tried to do this with mysql to connect at port 3306 using telnet it succeeded.
Second thing is that I tried to create a service name in oracle using TCP/IP protocol giving the above mentioned host names at all the attempts it gave the error that it has performed an illegal operation . I think that there are some settings needed for oracle to listen at this port which I dont know or I am giving the host name wrong . I shall be extremely thankful if u help me to solve this problem.

If you are using Unix/Linux you could ping where your db is and get the path name that way. However, it looks like you may just have to add another : in the path you have. ....:1521:Orca.... for example.
