Hi, I'm migrating a java class that connects through JDBC with an oracle 8.1.5 DB from JVM 1.1.6 to 1.2. I got the above error when trying to connect to DB. I changed the files classes111.zip to classes12.zip. I saw some tips about using a thin driver. I'll try to use this, but I would like to still use the oci driver. This is urgent!!! Thanks in advance!
