BatchInsertSQL - nvarchar2 - (17004) Invalid column type. ERROR

Hi All,

I am using BatchInsertSQL to insert values to oracle table which is having nvarchar2 fields.

nvarchar2 fields are NOT NULL fields.

While inserting data into table, i am getting the following error.
(17004) Invalid column type.


As I referred advantage site http://advantage.webmethods.com/article/?id=SR-1-64518051, suggested to
install patch JDBC_6-0-3_Fix15 or JDBC_6-0-3_FP1_Fix10.


Trying to install this patch in our server, we are getting version conflict error.
“Error: The version of the existing package does not match the version of the package to be installed. Installation fails”


Server Details : 6.1
Updates Installed:
WmPRT_6-1_SP2_Fix4
IS_6-1_SP2


WmJDBCAdapter package version : 6.0.3.1
(Still now there is no bug fix installed for This package)


Do you have any suggestion to solve this issue? Thanks!
