Hi. I am trying to load data from the file to oracle DB. When I use sesion.save(..) insert is successful, when I use session saveOrUpdate(..) I am getting error - org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.metlife.tmw.db.InstncLkup#123]. InstncLkup is just a POJO object

Here is my code:
Code:
String tableName = prepareReflectionObject((String)SessionManagement.getSessionScope("displayTableName"));
   Class<?> cls;
   try {
      session.beginTransaction();
      String classPath = "com.metlife.tmw.db." + tableName;
      cls = Class.forName(classPath);
         
         
      if(fileExt.equals("xls") || fileExt.equals("xlsx")){
         for(int i = 0; i< rows.size(); i++){
         Row row = (Row)rows.get(i);
         Object instance = cls.newInstance();
         for(int j = 0; j < alImportColumnInfo.size(); j++){
                      ColumnInfo ci = (ColumnInfo)alImportColumnInfo.get(j);
            String methodName = "set" + prepareReflectionObject(ci.getColumnName());
            if(ci.getDataType().equals("NUMBER")){
               method = ((Class<?>) instance).getDeclaredMethod (methodName, Double.class);
               method.invoke(instance, row.getCell(j).getNumericCellValue());
            }
            else if(ci.getDataType().equals("DATE")){
               Date colDate = importValidator.xlsCellToDate(row, j);
               method = ((Class<?>) instance).getDeclaredMethod (methodName, Date.class);
               method.invoke(instance, colDate);
            }
            else{
               if(row.getCell(j).getCellType() == Cell.CELL_TYPE_NUMERIC){
                  colValue = importValidator.xlsCellToString(row, j);
               }
               else{
                  colValue = row.getCell(j).getStringCellValue();
               }
               method = instance.getClass().getMethod(methodName, String.class);
               method.invoke(instance, colValue);
               
            }
         }
         method = instance.getClass().getMethod("setCreateTs", java.sql.Date.class);
         method.invoke(instance, new java.sql.Date(System.currentTimeMillis()));
                  
         method = instance.getClass().getMethod("setLstUpdtTs", java.sql.Date.class);
         method.invoke(instance, new java.sql.Date(System.currentTimeMillis()));
                  
         method = instance.getClass().getMethod("setLstUpdtUsr", String.class);
         method.invoke(instance, "bla");
         session.saveOrUpdate(instance);
      }
                }
      else{
               
      }
      session.getTransaction().commit();
      session.flush();
   } catch (Exception e) {
            logger.error("File Upload - loadValidRows");
            logger.error(e.getStackTrace());
            System.out.println(printStack(e));
            return "Problem importing the file";
         }


Here is xml file
<class name="com.metlife.tmw.db.InstncLkup" table="INSTNC_LKUP" schema="TFRMW" select-before-update="true">
<id name = "instncCd" column = "INSTNC_CD" type="java.lang.String">
<generator class="assigned"></generator>
</id>
<property name="instncDesc" column="INSTNC_DESC"/>
<property name="ftpSrvrNm" column="FTP_SRVR_NM"/>
<property name="ftpUsrIdTxt" column="FTP_USR_ID_TXT"/>
<property name="ftpPwTxt" column="FTP_PW_TXT"/>
<property name="ftpRmotDirTxt" column="FTP_RMOT_DIR_TXT"/>
<property name="activeInd" column="ACTIVE_IND"/>
<property name="createTs" column="CREATE_TS" />
<property name="lstUpdtTs" column="LST_UPDT_TS"/>
<property name="lstUpdtUsr" column="LST_UPDT_USR"/>
</class>

Here is stacktrace:
Hibernate: select instnclkup_.INSTNC_CD, instnclkup_.INSTNC_DESC as INSTNC2_0_, instnclkup_.FTP_SRVR_NM as FTP3_0_, instnclkup_.FTP_USR_ID_TXT as FTP4_0_, instnclkup_.FTP_PW_TXT as FTP5_0_, instnclkup_.FTP_RMOT_DIR_TXT as FTP6_0_, instnclkup_.ACTIVE_IND as ACTIVE7_0_, instnclkup_.CREATE_TS as CREATE8_0_, instnclkup_.LST_UPDT_TS as LST9_0_, instnclkup_.LST_UPDT_USR as LST10_0_ from TFRMW.INSTNC_LKUP instnclkup_ where instnclkup_.INSTNC_CD=?
