I am trying to connect to an Oracle database using a tomcat server through JDBC.
1. Do I need to enter the ip or host name of the tomcat server somewhere in oracle?

2. I am using both oracle 8.1.7 and 9i editions, are the drivers from Oracle backward compatable.

3. I keep getting the following error:
Java.sql.SQLException: Io exception: Connection

refused(DESCRIPTION=(TMP=)(VSNNUM=135294976)(ERR=1 2505)(ERROR_STACK=(ERROR=(CODE=12

505)(EMFI=4)))) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBE rror.java:168)
Any ideas on how to fix this?

Any help would be greatly appreciated.
Thanks you in advance.
