hi all

i want to access remote oracle database server 10g from jsp/servlet program

for this i followed this training

htt ps://ww w.jav a4s.co m/ja va-servlet-tu torials/ho w-to-connect- servlet-to-the-database-with-examp le/

and downloaded all the required files and taking care to consider the parameters of the non-local database

after that,i started tomcat server and executed the jsp/servlet program

but i am gettting the following error (maybe the configuration was not done properly)

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

Google the error message. I suspect this has nothing to do with Eclipse.

I solved the problem ORA-12505, TNS: listener does not currently know SID given in connect descriptor

now I get the problem ORA-01017: invalid username / password; logon denied

however my jdbc URL and my credentials are correct

jdbc url: Connection con=DriverManager.getConnection("jdbc:oracle:thin:@remote_db_ip:1521:apex","username","password");

if any one know,please explain me ....
thanks
