Migrating from Oracle 9i to 10g

My java application is using Oracle 9i, Now we need to migrate to oracle 10G
I am using WSAD 5.1.1
I have made following changes in server configuration to migrate to 10g

Variables Section:
I have changed in 'Variable' section of server configuration settings 'ORACLE_JDBC_DRIVER_PATH' to the location where my Oracle client is installed
for example
D:\oracle\product\10.2.0\client_2\jdbc\lib to have classes12.zip path

JDBC Provider:
I am using 'Oracle JDBC oci8 Driver' as a JDBC Provider

I have changed my connection URL to jdbcracleci8:username/password@ora10g

Now when I am starting my server i am getting following error

java.sql.SQLException: DSRA9002E: ResourceException with error code null: javax.resource.spi.ResourceAllocationException
