Migrating a table with BLOB field from SQL-Server to Oracle.

Question

Hi All,
I'm trying to create a Class to migrate data from SQL-Server to Oracle, this table has a BLOB field.
The Code:
package br.com.infox;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
public class Migrador {
     public static void main(String[] args){
          try {
               // Conex�o com o SQL Server
               Class.forName("net.sourceforge.jtds.jdbc.Driver");
               Connection conSQL = DriverManager.getConnection ("jdbc:jtds:sqlserver://10.10.2.9/protocolo","prot","suinf2002");
               // Conex�o com o Oracle
               Class.forName("oracle.jdbc.driver.OracleDriver");
               Connection conORA = DriverManager.getConnection ("jdbc:oracle:thin:@10.10.2.2:1521:des","protocolo","protocolo");
               Statement stSQL = conSQL.createStatement();
               String querySQL = "SELECT * FROM DOC_INCORPORADO";
               ResultSet rsSQL = stSQL.executeQuery(querySQL);
               String queryORA = "INSERT INTO PROT_VITALICIAMENTO (NU_PROCESSO, ANO_PROCESSO, CD_USUARIO, DT_ENVIO," +
                         "DE_COMPLEMENTO, NM_ARQUIVO, ARQUIVO, NU_SEQ, CD_TIPO_ARQUIVO, MES, ANO) VALUES (?,?,?,?,?,?,?,?,?,?,?)";
               PreparedStatement psORA = conORA.prepareStatement(queryORA);
               while (rsSQL.next()){
                    System.out.println("Linha: " + rsSQL.getRow());
                    psORA.setInt(1, rsSQL.getInt("nu_processo"));
                    psORA.setInt(2, rsSQL.getInt("ano_processo"));
                    psORA.setInt(3, rsSQL.getInt("cd_usuario"));
                    psORA.setDate(4, rsSQL.getDate("dt_incorporacao"));
                    psORA.setString(5, rsSQL.getString("complemento"));
                    psORA.setString(6, rsSQL.getString("nm_arquivo"));
                    psORA.setBinaryStream(7, rsSQL.getBinaryStream("arquivo"), (int)rsSQL.getBlob("arquivo").length());
                    psORA.setInt(8, rsSQL.getInt("num_seq"));
                    psORA.setInt(9, rsSQL.getInt("cd_tipo_arquivo"));
                    psORA.setInt(10, rsSQL.getInt("mes"));
                    psORA.setInt(11, rsSQL.getInt("ano"));
                    psORA.executeUpdate();
               stSQL.close();
               psORA.close();
               conORA.close();
               conSQL.close();
          } catch (Exception e){
               e.printStackTrace();
The ERROR:
java.sql.SQLException: Exce��o de E/S: Connection reset
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:334)
     at oracle.jdbc.ttc7.TTC7Protocol.handleIOException(TTC7Protocol.java:3668)
     at oracle.jdbc.ttc7.TTC7Protocol.doOall7(TTC7Protocol.java:1986)

     at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:658)
     at br.com.infox.Migrador.main(Migrador.java:41)
What's the problem of these Class?
Thank's.

Depending on the version of the database you have, you could use transportable tablespaces.
