    Unanswered: Oracle 8i JDBC thin Driver problem.

    Hi ,

    I'm trying to access an Oracle 8.1.7 remotely from
    a Java Program on Win 2k. I have downloaded the for Oracle 8.1.7 for use with jdk 1.1.x
    on Win NT from the Oracle technet site and placed it
    in my classpath. The java program compiles too absolutely
    fine. But I get the following error at run time.

    java.lang.IncompatibleClassChangeError: Unimplemented interface method
    at oracle.jdbc.driver.OracleDriver.getConnectionInsta nce(OracleDriver.ja
    at oracle.jdbc.driver.OracleDriver.connect(OracleDriv
    at java.sql.DriverManager.getConnection(Compiled Code)
    at java.sql.DriverManager.getConnection(DriverManager .java:163)

    Any body has come across this ? Any help on this would be really really

    Hi ,

    I think there is a version mismatch problem.So it is better to use
    JDK1.3 which is free at Sun site.I have been using it for quite some time.I think you need to place in the classpath as it contains the driver.I dont remember you can do is just unzip the file and see if it contains the oracle driver or not.Otherwise put in the class path which comes with oracle8.1.7 If the problem still persists put and in the classpath also.First run a simple program to connect to oracle and get one resultset from any table firing a query.

    For further query please feel free to mail at
