    Hi,

    While trying to get a connection in JDBC I am getting the error: java.sql.SQLException: Protocol violation.

    I don't have any problem with JDBC connection with another Oracle instance on the same machine.

    I am using using Servlets in iPlanet web server. The code was working earlier but somehow it is not working now. I suspect it may be something to do with the Oracle db.

    Anyone knows why I am getting the Protocol violation error and how it can be resolved?
    Regards,
    Jack

    How is your JDBC connection implemented? Do you use ODBC or Oracle thin or oci JDBC?

    Guys,

    I managed to solve the problem (with Oracle metalink help). When I use Oracle9i JDBC driver, there is no problem. But my db is Oracle8.1.7. JDBC drivers are backward compatible.
