Table View Sorting Problem

Hi SDN,

I am developing a Java iView with table view

I am getting Data from R/3 using JCA connectivity

and can able to display IRecordSet in table view

now i want the data to be sorted in multiple columns

can any one provide me how to proceed further , thank you in advance

please find the attached code below

public void getInitialData(){

IPortalComponentRequest request = (IPortalComponentRequest)getRequest();

String BAPI_InitialData = request.getComponentContext().getProfile().getProperty("BAPI_InitialData");

String ADD_ON_APPLICATION = request.getComponentContext().getProfile().getProperty("ADD_ON_APPLICATION");

String PLAN_VERSION = request.getComponentContext().getProfile().getProperty("PLAN_VERSION");

String userid = request.getUser().getUniqueName();

this.getConnection();

try{

IInteraction interaction = connection.createInteractionEx();

IInteractionSpec interactionSpec = interaction.getInteractionSpec();

interactionSpec.setPropertyValue("Name", BAPI_InitialData);

RecordFactory recordFactory = interaction.getRecordFactory();

MappedRecord input = recordFactory.createMappedRecord("input");

input.put("ADD_ON_APPLICATION",ADD_ON_APPLICATION) ;

input.put("PLAN_VERSION",PLAN_VERSION) ;

input.put("USER_NAME",userid) ;

MappedRecord exportParams = (MappedRecord) interaction.execute(interactionSpec, input);

IRecordSet templatetable = (IRecordSet)exportParams.get("T_TEMPLATES");

myBean.setTemplates(templatetable);

myBean.createNewTable(templatetable);

String default_template = (String)exportParams.get("DEFAULT_TEMPLATE");

myBean.setDTemplate(default_template);

Date begda = (Date)exportParams.get("FROM_DATE");

myBean.setBegda(begda);

//myBean.setBegda(begda.toLocaleString());

Date endda = (Date)exportParams.get("TO_DATE");

myBean.setEndda(endda);

connection.close();
