Good news: I am able to import the "WrappedCallableStatement" file. The issue was due to the conflict between the same files at two different locations. Now I am having exception at the following line (Above code): cstmt.registerIndexTableOutParameter(1,maxTablLen,OracleTypes.VARCHAR,eleMaxLen); The exception is: "Unsupported feature".
