In a program I'm making the following statement:
Connection conn = DriverManager.getConnection("jdbc:oracle:oci8:@amdd","s00xxxx","amdd");
On my old PC this statement works. I've migrated to a new PC and now the statement fails as follows:
java.lang.NullPointerException
at oracle.jdbc.oci8.OCIDBAccess.check_error(OCIDBAccess.java:1581)
at oracle.jdbc.oci8.OCIDBAccess.logon(OCIDBAccess.java:354)
at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:249)
at oracle.jdbc.driver.OracleDriver.getConnectionInstance(OracleDriver.java:365)
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:260)
at java.sql.DriverManager.getConnection(DriverManager.java:512)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
at Database.main(Database.java:49)
I have both 8i and 8 components installed on both PCs.
I've checked the tnsnames.ora, sqlnet.ora, and registry entries (for homes) and the settings are the same (same locations and the same contents). The client works the same from both machines. What could I be missing (from a configuration standpoint)? Does OCI have some more specific configuration file(s) or registry entries?
Thanks in advance for your help,
--Chris

I resolved the issue by using a different classes12.zip in my classpath. It seems there was a conflict with the one I had moved from one environment into the next with my deployment package. I changed my classpath to use the existing one in the oracle installation on my machine and it worked. You could try using the new classes12.zip in the installation of oracle on your machine.
