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.

Dorj, Seems that you've tried everything. Nope , there's one thing u could do to be sure that the listener is currently listening: go to the command prompt and type : lsnrctl or lsnrctl80 which ever one that will work. after that type in : start then type: quit then try your code. ------------------ KaReEm [This message has been edited by Kareem Gad (edited August 06, 2001).]

Write this one (jdbcracle:thin:@127.0.0.1:1521 rcl",props); // this is Connection function public Connection getConnection() throws SQLException { try{ Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); } catch (ClassNotFoundException cnfe) { throw new SQLException(cnfe.getMessage()); } catch (IllegalAccessException iae) { throw new SQLException(iae.getMessage()); } catch (InstantiationException ie) { throw new SQLException(ie.getMessage()); } System.out.println("OracleDriver loaded Successfully....\n"); Connection con = null; Properties props = new Properties(); props.put("user","scott"); props.put("password","tiger"); try { con = DriverManager.getConnection("jdbc racle:thin:@127.0.0.1:1521 rcl",props); return con; } catch (Exception e) { System.out.println("Exception :::"+e.getMessage()); throw new SQLException (e.getMessage()); } }

I have tried that code but the problem is that the code is perfectly alright driver is also perfect but the problem is with the data base it is not listening on the port 1521. I have tried to connect with it at host 127.0.0.1 at port 1521 using telnet but it gives a window error message . On the other hand i tried to connect with mysql at port 3306 using localhost it succeeded. My idea is that the oracle supports such an activity on winnt or win2k.Thanx for ur help.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
