How to call stored procedure with IN-OUT parameters in batch?

Hi All,
Urgent!!
I am badly stuck in one issue. I want to call oracle stored procedure in loop. Store procedure has IN and OUT parameter. i can’t replace store procedure with any other thing as my requirement is like that only.
1. I know how to extend StoreProcedure class but in that approaches i will end up in calling execute method in loop which i think is not good approach.
2. I tried to use jdbcTemplate.batchUpate but in that case when I am trying to override setValue method of BatchPreparedStatementSetter class I am not able to set out parameters as it use prepared statement object. Even I tried to type cast prepared statement to callable statement but it throwing me below error as I am using JNDI datasource of IBM WEBSERVER.

java.lang.ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcPreparedStatement incompatible with java.sql.CallableStatement

Your help is highly appreciated.
