I have a OC4J application running in oracle application server 10g. It currently connects to an 11Gr2 database using an oracle thin jdbc connection. I'm trying to connect the same app to a 12CR2 database again using the thin jdbc connection with no success. this is the error:
Unable to establish connection for one or more OC4J instances in the group. Below are the results for each OC4J instance.
"my OC4J: on "my site" - Failed due to error: "Exception occurred testing connection. Exception: java.sql.SQLException: Io exception: Got minus one from a read call."
I'm assuming it's due to a jdbc version issue. I can connect via sqldeveloper to both dbs. Any thoughts with updating the jdbc on the application server side would be appreciated.
thanks
