Grails 3 unable to resolve class oracle.sql - oracle

Question

Trying to run a grails 3 application with jdbc6 dependency. I'm trying to import the below libraries in my groovy service that is supposed to connect to an Oracle database to call a stored procedure.
import oracle.sql.ARRAY
import oracle.sql.ArrayDescriptor
import oracle.jdbc.OracleCallableStatement
import java.sql.Connection
import groovy.sql.Sql
import org.apache.poi.ss.usermodel.Workbook
import org.apache.poi.ss.usermodel.WorkbookFactory
import org.apache.poi.ss.usermodel.Sheet
import org.apache.poi.ss.usermodel.Cell
import org.apache.poi.ss.usermodel.Row
import org.apache.poi.ss.usermodel.DataFormatter
import com.wwt.itemuploadapi.rectypes.Rectype
import java.sql.SQLException
class ExcelService {
def dataSource
private static final FILE_HEADERS = [
'First Name': 'firstName',
'Last Name': 'lastName'
]
def callApi(List<Rectype> rectype) {
OracleCallableStatement callableStmt = null
try {
def conn = dataSource.getConnection()
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("TBLTYPE", conn.unwrap(oracle.jdbc.OracleConnection.class))
ARRAY dataElementsArray = new ARRAY(descriptor, conn.unwrap(oracle.jdbc.OracleConnection.class), (Object[])rectype.toArray())
Map map = conn.getTypeMap()
map.put("REC_TYPE", Rectype.class)
callableStmt = (OracleCallableStatement)conn.prepareCall("{call package.procedure_name(?)}")
callableStmt.setArray(1, dataElementsArray);
callableStmt.execute()
}
catch (SQLException ex) {
println(ex)
}
}
I get the below three errors upon starting up. But I have these classes under my Gradle: com.oracle:ojdbc6:11.2.0.3 library. So I'm not sure why it can't recognize them.
`unable to resolve class oracle.sql.ARRAY`
`unable to resolve class oracle.sql.ArrayDescriptor`
`unable to resolve class oracle.jdbc.OracleCallableStatement`
Any suggestions why these classes can't be found?

Answer 1

oracle.jdbc.OracleCallableStatement
is not the correct class to use anymore for the ojdbc dependency version you are using.
That should be updated to this import and class:
import java.sql.CallableStatement
CallableStatement callableStmt = null
Here is a link which will show you what you need to do to replace the other deprecated classes (oracle.sql.ARRAY and oracle.sql.ArrayDescriptor) you are trying to use:
