Hi All,

The setenv.bat has the following variables set:-
set DRIVER_CLASSPATH=C:\Jdeveloper\oc4j\jdbc\lib\ojdbc14dms.jar;C:\Jdeveloper\oc4j\jdbc\lib\ocrs12.jar;C:\Jdeveloper\oc4j\jdbc\lib\orai18n.jar;C:\Jdeveloper\jdbc\lib\ojdbc14.jar;
set JAVA_HOME=C:\Jdeveloper\jdk
Please could somebody help me with this error?
Thanks.

Answer 1

Got this problem fixed. Forgot to include dms.jar in the DRIVER_CLASSPATH environment variable in the setenv.cmd file of top link
So changed it to include the dms.jar file as follows:-
set DRIVER_CLASSPATH=C:\Jdeveloper\oc4j\jdbc\lib\ojdbc14dms.jar;C:\Jdeveloper\oc4j\jdbc\lib\ocrs12.jar;C:\Jdeveloper\oc4j\jdbc\lib\orai18n.jar;C:\Jdeveloper\jdbc\lib\ojdbc14.jar;C:\Jdeveloper\oc4j\lib\dms.jar;
and the toplink seemed to connect to the db.
Thanks.
