Below code shows the way to write CLOB fields to the database:

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

/**

 */
public class ClobTest {

 public static void main(String[] args) throws Exception{
 Connection con = null;
 CallableStatement stmt = null;
 
 try {
 
  Class.forName("oracle.jdbc.driver.OracleDriver");
  con = DriverManager.getConnection("jdbc:oracle:thin:@IPAddress:Port:Database",
    "username","password");
  stmt = con.prepareCall("{call CLOBTEST.saveClob(?)}");
  String xmlString = "1234567890";
  
  stmt.setAsciiStream(1,new ByteArrayInputStream(xmlString.getBytes()),
     xmlString.getBytes().length);
  
  stmt.execute();
  System.out.println("executed successfully");
  
 }catch(Exception e){
  e.printStackTrace();
 } finally {
  try{
   if(stmt != null){ 
    stmt.close();
   }
   if(con!= null){
    con.close();     
   }
  }catch (SQLException e) {
   e.printStackTrace();
  }
 }
